The Elephant in the Video Conferencing Room

The fundamental challenge of running enterprise-wide video conferencing (VC) is keeping users happy. Happy users feel empowered, not foolish when confronted with the challenge of setting up or running a VC meeting. If you keep users happy you have most likely cut support costs while increasing utilisation – both metrics critical to any AV service manager come review time.

However for some inexplicable reason the VC industry as a whole has done a very poor job of keeping users happy. Regardless of what the respective vendor marketing departments say, most VC users consider the experience to be at best annoying, at worst completely off-putting. Integrators try to put lipstick on the vendor-grown pig, but inevitably only add cost and introduce unneeded complexity.

Top 5 Video Conference Self-Service Pointers

What you should take into account while introducing video conference self-services

The deployment of video conferencing booms in many companies. This way they can save costs and increase productivity. In earlier days video conferencing was reserved for top management but this has changed fundamentally. Today video conferences are used by all employees for their daily communication.

Today many companies own 500+ video conference rooms and 10thousands of desktop video conference users. The demand for professional video conferences is growing further and has been up to 30% a year.

The company’s structure used to be set up in a way to correspond to the needs of top management as a strictly controlled managed service. This strictly controlled managed services offers a high security standard for the company, however accounts for a big amount of the budget at the same time.

A remedy can be found in video conference self-services. The big advantage here is the high scalability and the reduced costs compared to the encompassing managed service. The video conference self-service should generally serve as an addition to the existing managed service structures.

Anyone thinking about implementing a video conference self-service should take note of the following five points:

1. User expectations

In case you use a high quality managed service already, it will not be an option to not use this service in the future. It is important to manage the user expectations and clearly state for which purposes the self-service is intended. A self-service should predominantly be accessible for all employees. The managed service still makes sense for important meetings of the top management, etc. It can be helpful to communicate the costs of the managed service transparently to the users – a measure which might change their mind rather quickly.

2. Video conference infrastructure

Be aware that existing video conference infrastructure often is not tailored to the needs of the video conference self-service. Ordinary video conference infrastructures only enable low scalability, which means that video conference ports are not unlimited. It might make sense to use a software based video conference structure. These allow for high scalability and low operation costs. Initially it might make sense to use a cloud video conference service.

3. Planning business as usual

Video conference self-service does not mean that normal business can be compromised and the solution automatically works – to the contrary! For high user satisfaction the video conference infrastructure has to be stable, questions of users have to be answered timely and competent and the administration of accounts and virtual video conference rooms has to be managed.

4. Offer trainings

If you offer a video conference self-service, you also have to educate the users in a way that they are able to use the service right. Training is important. That can be seminars, booklets, eLearning training videos and intranet pages.

5. Manage growth

The introduction of a video conference self-service can lead to an enormous demand. Some companies measured the double demand within a year. Pay attention to the impact on your network and on your video conference infrastructure as well as on the daily business. The budget planning should grow too, because financial resources are especially scarce during the year.

I hope these are some good pointers for all our readers considering to look into add a self-service to their portfolio. If you have made any experiences yet around this or just want to share your thoughts, please feel invited to do so in the comments box below. Many thanks!

What is “the Cloud”? And what is it not?

cloud-sky-photography-city-scape-sun-flare-skyline-blue-summer-light-cloudy

Clouds on summer sky (Photo: fastjel)

The Cloud – One of the hottest buzzwords and most abused in describing products or services recently. In this article I would like to mix facts with personal experiences I made, in order to assist everyone, who would like to find out what the cloud is and does and the things that is does not do (hence the title). Cloud has been buzzing around for a while now but when I witnessed both my parents talking about “the cloud” and how they use it in private I understood that this technology has arrived in mainstream and it is here for good.

Cloud??

So what is the cloud in few words? The cloud, or cloud computing is a technology design to enable users working with solutions independent from device, location and network. Of course there are specialisations with a larger or smaller focus on one or two subjects but in general this is it.

Origin of the Term

There are many theories on the origin of the term, yet there is no proven story. Feel free to check some good options on the Wikipedia article for cloud computing. My theory is that it developed from the use of cloud clip-arts and stencils in technical drawings or presentations, created to visualise a network setup. I am sure that even before the term became a buzzword, most of you have seen presentations with little black boxes, switches and routers in and around a large cloud to set a virtual border between realms.

Is the Cloud something new?

I am afraid it is not. The ideas and designs for such concepts have already been around since the 1950s but like with many breakthroughs in the user world, it required certain cultural and technological thresholds to be reached before the adoption could take place on wide-scale.

What is the Cloud?

  • Agility – The cloud is agile and therefore allows users to upscale or downscale their service based on business demand. Further the actual hardware, used to host a virtual machine, can be re-purposed if necessary. This is however not a cloud-only benefit, please read further down on infrastructure virtualisation.
  • Availability – Services have the technological possibility of being available independent from devices, network and location. This is of course relative to the design of each service along with its purpose but technically this is no limitation. For instance you can use cloud video conferencing services to join any enterprise-grade video conference call from your smartphone, notebook, office workstation, tablet or even from a private computer at your home or maybe somewhere else. Of course your conference partner needs to have their own environment set up to accept connections from outside in general. Cloud technology is not a wall-breaker and cannot bypass security of an organisation, if they don’t allow such connections by policy.
  • Business Continuity – Cloud services are set up with redundancy and failover automation in place. So that even if single devices would fail, users would not notice and can proceed using the service. Such reliability would traditionally cost a lot of money when investing in owned or dedicated infrastructure black-boxes.

What is the Cloud NOT?

  • Cloud = VirtualisationVirtualisation of infrastructure is a great way of deploying new solutions and upgrading your environment. But if you do this within your WAN this does not automatically mean you are using the “cloud”. You are just virtualising your infrastructure. Fair and square.
  • “No more hardware” – Well that’s a lie. Using software solutions or virtual infrastructure there will still always be servers and databases that require a physical body. Only the deployment and usage is changed but there will always be hardware. You might not own the hardware and you will most likely never see or touch it but it’s there, somewhere in a physical data centre.
  • Grid computing – No, grid computing is not the same as cloud computing in my opinion. Even though, it might be its scientific opposite. Where grid computing allows many computing units to work on a common target (e.g. movie rendering in render farms or Bitcoin mining), cloud computing allows a single user to utilise just any infrastructure in the pool offered by the cloud service provider to achieve their objective.
  • “Private Cloud” needs to be on-premises – No that’s not correct even though it seems to be a common assumption. A cloud service can be deployed dedicated for your organisation without anyone else having access to it, but the location of the physical hardware is irrelevant in order to provide that. In most cases the service provider will utilise hardware that is physically near to the user base in order to avoid performance issues that could occur on long “open internet” routes.

Challenges of Cloud Technology

  • Security – Any cloud service can be set up in secure manner if the solution and the environment of the clients allow it.
  • Privacy – Yes, privacy is a hot topic nowadays. But actually, it always were even in pre-internet age. Privacy is nothing impossible even in the cloud, even in the internet if you choose the right service provider. And if you are looking for good providers but affordability is a concern, make sure that your selected partner has a few good reference clients to show-case to you.
  • Compliance – When you are in phase 2 of the provider selection, bring in the techies of your organisation to make sure all offered functions and features are compliant to any active IT security policies that you need to consider.
  • Vendor Strategy – Cloud providers equal single vendor lock-in? Yes, it can be the case but if you want to avoid that, talk about this particular subject with your provider candidates. A few providers out there have established alliances and offer support to avoid any lock-ins.
  • Online works, offline it doesn’t – Depending on what your solution looks like make sure that your workforce  can use the solution when they are online and when they are offline. For instance when changing a file being on a flight, the data should update and synchronise itself in the cloud again when they are online. However there are some services which this does not apply to such as real-time communication (e.g. WebRTC, video conferencing, VoIP telephony, instant messaging).

Examples of Public Cloud Solutions

Summary

I hope this cleared some confusion around cloud terminology and technology. Further I hope it helped you through your process of picking a good service provider for your organisation if that was your objective. Further I would like to thank Simon Dudley of LifeSize and Phil Karcher of Forrester Research for hosting the webinar, which sparked the inspiration to write this article. LifeSize is often arranging interesting webinars and announces them on their social media platforms. Maybe I will see you on their next event – until then.

Software MCU Comparison – What does the market offer?

A Videoconference Multipoint Control Unit (MCU) is a crucial part of every serious Videoconference infrastructure. It’s a system used to connect multiple media streams into a single Videoconference, therefore very often the MCU is referred to as a “bridge”.

The traditional MCU is a DSP (digital signal processing) based hardware whose primary functionality is to decode all incoming media streams, compose a single stream for each far-end participant and finally re-encode that stream before sending it out, needless to say all this requires a huge amount of processing power. More over, hardware-based MCUs define scalability on a per-port basis, which means if we want to have more participants connected in a Videoconference at the same time, we need MCUs with more video ports i.e. more DSPs and DSP hardware does not come cheap.

LifeSize UVC Multipoint used on a Tablet

That is why a lot of companies are turning their attention towards a new type of product when it comes to multipoint Videconferences – the so-called “software MCU” or soft-MCU. A soft-MCU serves the same purpose as the hardware-based, except that all the transcoding and signal processing is done in the software which introduces big advantages in terms of cost, scalability and flexibility.

The soft-MCU eliminates the need for DSP hardware and can run on virtualized servers on private or public clouds, therefore it is significantly cheaper to deploy than the expensive hardware MCU. In terms of scalability, customers can often just purchase the number of ports they require at the time and then scale up or down easily as the need changes. Software MCUs offer also more flexible deployment, updates and feature enhancements are easy and more frequent, which gives them advantage in today’s fast evolving demands in the Videoconferencing world. Manufacturers can offer the soft-MCU for on-premise deployment on company’s internal servers (usually preferred by enterprises) but the lower end of the group video conferencing market will also benefit from the hosted services (cloud services) offered by providers.

Current market of Software MCU solutions

Although still in relatively early phase in terms of adoption, the market is all but short in offering soft-MCUs solutions for multipoint Videoconferencing. Some of them offered as pure software to be installed on industry-standard servers, some of them require some sort of hardware usually from the same provider which makes them a kind of  “hybrid” solution. I will just go briefly through some of the most talked about products out there at the moment:

 Avistar

Avistar offers the Avistar C3 Conference, a software-based MCU that runs on standard off-the-shelf hardware and operating system software, and on virtualized servers. It is mainly designed for on-premise deployment in enterprise environments, but service providers offering managed Videoconferencing services could also take advantage from it.

Each conference server can support up to 12 ports of simultaneous conferencing, video standards supported are H.263 and H.264 up to 1024 kbps call rate per endpoint with 30 fps.

 Polycom

The Polycom RealPresence Collaboration Server 800s, Virtual Edition is a multi-protocol, integrated, software-based multipoint MCU running on x86 servers. Mainly designed for mid-sized enterprises or to expand an existing RealPresence Collaboration Server (RMX) environment, it provides open standards scalable video coding (SVC) support and interoperability with systems that use advanced video coding (AVC). It can support up to 40 H.263 or H.264 video ports with 720p and 30 fps.

 Vidyo

Vidyo solution consists of Vidyo Router at its center, offered also as a virtual edition (VE), which performs transcoding-free packet switching using their patented Adaptive Video Layering (AVL) technology which introduces low-latency video-streams for endpoints over any IP network. It can be deployed on industry standard servers and is “VMware Ready” certified. Interoperability with legacy systems requires the use of VidyoGateway. The VidyoRouter VE comes in two models – VE 100 and VE 25 offering 100 and 25 concurrent HD connections respectively, supporting native rate and resolution matching per endpoint, up to 1440p at 60fps. Vidyo technology is available through service providers such as Videoconference24.

 Pexip

Pexip is a new start-up that offers pure-software based MCU called Infinity, which will be available from September. It can be deployed on industry-standard servers in a VMware virtualized environment and port capacity can be easily scaled up by adding more servers. It will support H.263 and H.264, SVC, VP8 video codecs as well as interoperability with WebRTC and Lync. We are yet to see how this product will perform in the real-world but it definitely looks promising with of supporting wide range of software clients and endpoints.

Acano

Acana Software MCU Example

Acano is also also a new player in the industry, offering software solution that unites “previously incompatible audio, video and web technologies” in “coSpaces” which are essentially cloud virtual meeting rooms. People can use whatever devices they have to call into a coSpace, including mobile phones, tablets, PCs, Microsoft Lync clients or video endpoints. Designed for the x86 architecture, it runs on their optimized hardware, standard servers, as well as in virtualized environments and can support thousands of users per server, with further scale and resilience provided by native clustering. Major video standards are supported including H.264 AVC, SVC, WebM / VP8, Microsoft RTVideo, and said to support H.265 as well.

 Vidtel

Vidtel is primarily a service provider; does not offer soft-MCU for on-premise enterprise deployment, but they do offer hosted cloud Videoconferencing solution, labeled MeetMe – it’s a cloud-based, “any-to-any” video conferencing service which supports interoperability between SIP, H.323, Google Talk, Skype, and WebRTC. It supports up to 20 video conferencing endpoints with 720p. The infrastructure for video conferencing is hosted on a Vidtel central cloud and each participant is given a private meeting room ID and a login PIN; they use this to join the Vidtel MeetMe meeting and start communicating and interacting almost as if they were in the same office.

 LifeSize

LifeSize UVC Multipoint is a software-MCU that can be installed on industry-standard servers. It supports H.263 and H.264, SVC video standards and interoperability with Lync (Microsoft RTVideo). Customers can purchase and scale one port at a time and administrators can selectively control the quality and capacity of each port, ranging from 360p for mobile users to 1080p for room-based environments (with the Enterprise edition) and maximum of 128 participants in a single conference.

 Cisco

Cisco became the undisputed king in Videoconferencing hardware, with the acquisition of Tandberg, but they do not offer software-MCU that can be deployed on-premise. They do however offer cloud Videoconferencing service called – Cisco WebEx Telepresence, which can support up to 12 participants per conference with 1080p. At the moment it’s only available in the U.S. and Canada.

 Blue Jeans Network

Blue Jeans – similar to Vidtel, Blue Jeans is a service provider offering hosted hosted video bridging with multi-vendor interoperability including Skype and Lync. Also they are the developers of their own solution and allow re-selling. It supports up to 25 participants per meeting with 720p at 30 fps  and offers easy web based management capabilities for administrators as well as reporting capabilities.

 Avaya / Radvision

Avaya / Radvision is offering the Elite 6000 Series – software-based hybrid multi-point control unit providing high port density up to 40 full 1080p HD ports (80 720p) on a single 1U system. All the major video standards are supported as well as interoperability with other vendors.

As we can see there are lots of different flavors and there are more solutions out there, opening new opportunities for those who could not own standalone MCU before. It’s hard to say what the future holds, certainly it’s too early to dismiss hardware-based MCUs in which companies have invested a lot of money. It’s clear that the two solutions will coexist for some time and it’s up to the customers to choose the best solution for their business based on their requirements in usage, cost and features.

Can Your Business Benefit From Cloud Computing?

cloud, computing, benefits, icon, business

Simply put, cloud computing is computing based on the Internet. So, instead of running programs or applications on a physical server, cloud computing allows you to access the same apps and software online, without needing to download or install them. Web applications, including but not limited to email, document sharing, instant messaging and more, are all designed to make it easier to collaborate and get work done no matter where you’re located.

From reducing costs to improving communication and collaboration to enhancing productivity, the benefits of cloud computing are countless.  Because of this, it’s important to understand the benefits of cloud computing and just why so many businesses are moving to the cloud.

 1. Reduced costs

Moving to the cloud will not only help you reduce costs on infrastructure and software but you’ll also be able to invest more money back into your business in research, marketing strategies, product innovation and anything else you need. Using the cost savings from cloud computing to free up resources will give your business a strong competitive advantage in the market.

With cloud, you only need to pay a small amount of money in return for a huge amount of storage space. Plus, cloud resources are easily scalable which means they can be altered to suit your exact needs as your business grows.

2. Disaster recovery

Did you know that 800,000 laptops are lost each year in airports alone? Although replacing the laptop may be costly, what do you do about everything you have saved on it? When you have everything stored in the cloud, you no longer have to worry about losing or not being able to access your data because it’s all in the cloud, safe and sound.

If you’re a business owner, cloud-based services will also help you solve issues faster in the event of a disaster. In fact, a recent survey conducted by the Aberdeen Group revealed mid-size businesses took almost half the time it took larger companies to recover after a disaster because of their commitment to the cloud. Furthermore, cloud-based disaster recovery services were able to get companies up and running again in 2.1 hours, compared to eight hours for those not using the cloud.

3. Automatic software updates

Using the cloud means you’ll no longer have to worry about purchasing, installing, downloading and updating software. Cloud computing suppliers take care of this for you – security updates included – thus freeing up your time so you can focus on other important aspects of your business.

Not only does this save you hassle, but it also means you don’t have to worry about hackers exploiting out of date software.

4. Increased collaboration

Cloud computing makes collaboration easy as all employees – no matter where they’re located – can access and work on shared documents at the same time and don’t need to keep sending them back and forth over email. This is a huge benefit of cloud computing as all files are stored in a central location which means employees can talk to each other while making changes to the central copy at the same time. The collaboration is simplified and it translates to business efficiency as no time is wasted on uploading and emailing files and waiting for updates.

5. Work from anywhere using the cloud

You can have employees working from anywhere in the world, so long as they have an Internet connection. In addition, the cloud has also become more accessible via smartphones and tablets, which means that you really can have access to your documents anytime and anywhere.

As you can see, the reduced costs, the flexibility and security provided by cloud computing can truly give a business leeway to focus in its core priorities.

Can you think of any other fantastic benefits of using cloud computing? Go ahead and share them with us in a comment below.

Deutsche Telekom discontinues VideoMeet

Deutsche Telekom, Logo, Telekom Logo, Magenta, T-Systems, T-Online, T-Mobile, VideoMeet, Video Conferencing, Cloud, Immersive Telepresence, WebRTC, Skype

Source: Wikipedia

The cloud video conferencing solution VideoMeet by Deutsche Telekom in corporation with Blue Jeans Network is now confirmed to be discontinued by end of the year. The decision was first published by the German  expert magazine “Telecom Handel” in an online article yesterday by Waltraud Ritzer.

What is VideoMeet?

The solution was designed to bring different types of video conferencing devices and software clients together with Blue Jeans cloud technology. The VideoMeet solution was first introduced in June 2011 and has seen strong marketing campaigns. In addition to the virtual MCU and the interop between systems of many different vendors, Blue Jeans technology was first to natively bridge Skype participants into professional video conferences. In 2012 more compatibility features were announces such as the integration into Microsoft Lync or using the service directly out of the Browser with WebRTC.

What’s next?

Starting from January current users can switch to a new model by Deutsche Telekom, which is yet to be announced, or get the service directly from Blue Jeans. Spokesperson Marion Kessing says that unlike the cloud solution VideoMeet, Immersive Telepresence and other video conferencing options of Deutsche Telekom will be extended.

Next to the user base this also hits redistribution partners as they will have to find an alternative cloud video conferencing solution for their clients and integrate it into their service portfolio before January. Seeing the increasing demand for cloud video conferencing a complete removal of the service is unlikely.

Cloud video conferencing alternatives?

Users and redistributors alike might now be interested in alternatives such as examples that can be found on our recent cloud video conferencing solution comparison. In addition to that of course like always we would love to hear your opinion and the experiences you have made.

How To Maintain Security With Teleworking

Padlock (Photo credit: Moyan_Brenn)

Advances in mobile technologies and networking have made it possible for more people to work in the convenience of their homes or outside the office, also known as teleworking. We can work anywhere – client offices, hotels, cafés, beach resorts, etc. This has made virtual companies possible and has made tapping talent from far away possible.

While it is convenient to work from different places, the devices you use are also vulnerable to malware and viruses. These things can also infiltrate your company network and these criminals can steal your company data. Smartphones and tablets are very susceptible to threats as they can easily be stolen. Your company may experience a lot of problems if your employees’ devices get comprised. Tighten your security with these tips.

Protect devices

Your first line of defence against cyber criminals are firewalls, antivirus software and strong passwords. In an ideal world, you should be able to bring your devices anywhere, connect to the Internet and do your work. That is just not the case in the real world as free Internet and public connections are very high risk. You also can’t prevent your employees from opening their personal mail and browsing the Internet especially if they are using their own devices.

Train your employees to regularly update their protective software or better yet, turn on auto-updates in the settings. Install encryption software in your devices too so you can prevent unauthorized people from accessing your data. You should also install a remote-wipe program in case the device gets stolen.

Use cloud applications

Cloud application providers have invested in robust security systems to keep your data protected. If you can’t invest in security software, use cloud applications instead. This is an affordable option for small businesses. If you need more specialized tasks, you can get them starting at $5. That’s not a bad investment especially if you can get peace of mind knowing that your data is safe. Remember to use strong passwords for your accounts.

Secure the company network

Your employees should be able to securely connect to your corporate network. The traditional system used is a Virtual Private Network or VPN that encrypts the employee’s internet traffic. It also has tools to make sure that remote computers have security patches. It can also monitor a machine for potential infections. There are different providers for this kind of security and you can surely get one that fits your budget.

Remote working gives both employees and the company a lot of benefits. The key is to be able to provide a secure working environment wherever your employees are.

How Unified Communications Can Improve Your Business Strategy

Unified Communications in Enterprises (photo by Victor1558)

More and more businesses are using advances in technology to further their reach and expand. A number of businesses are already familiar with Skype, and that tool has enabled businesses to contact clients and team members who may work from home at a seconds notice. Unified Communications have created a system that has all the benefits of Skype and incorporates other forms of communication too, making it the complete package.

What is Unified Communications?

Unification of communication systems can really give your business a competitive edge and enable you to keep all your forms of communication in one place, making it easy to maintain and man-manage on a day-to-day basis. It enables you to combine telephone and business data on one single network, and gives you the flexibility in your communication to combine and use voice, video and data in applications. You can also save and forward instant message streams, phone calls, faxes and emails, voicemail and video conference sessions as data files. This way, nobody is left out of the loop.

The data is encrypted to ensure that it cannot be obtained and fall into the wrong hands, giving you complete security when passing data across your network. If there is sensitive or important information being sent across, you can rest assured that it will stay in the appropriate circles, regardless of whether it is sent in the form of an email, voice call or video.

How Can Unified Communications Improve My Business Strategy?

The name of the game here is ease of use and a lack of complication. When you have ten plates spinning, there’s a good chance that any could become neglected and fall. Unified Communications allows you to keep everything in order and in one place, meaning that one person can take care of everything if need be, and without any confusion or frustration. The team member can use a single phone number or handset and a unified inbox for all the available communications too. An easier life for your team is the ultimately goal for everybody, and this system provides it.

Cost Saving

Every business strategy needs a budget in place, and every business needs to know what costs are going to be made and saved by the strategy they put into place. Unified Communications save businesses a great deal of money by having all of your communications related outgoings being billed as one item. This makes it a great deal easier for businesses to set a budget and fill out a profit-and-loss. If a business can budget easier, it makes it a lot less difficult to plan ahead.

The systems are pretty inexpensive too, meaning that more small businesses are turning to Unified Communications so that they can save on a variety of systems they would have to set up individually and just focus on the one system that unifies everything, from voice, to email, fax and SMS.

Time is a valuable commodity when putting together a business strategy, and with a unified communication system in place, you can save time and money on training team members on how to use a variety of systems. Once you have a team member trained to a high standard on a unified system, you would have covered all channels of communication, which in turn will help keep your customer service to a high standard and improve efficiency.

Improving Customer Service

Every business strategy has to include ensuring that the customers are taken care of and that their issues and queries are dealt with quickly and effectively. A number of customers will make their complaints heard via social media, email, fax and by telephone contact, so it is essential that all businesses have a clear strategy for taking care of these customer service issues the moment they arise. With a unified communication system, a query or complaint will be noticed immediately, and can be actioned right away. It also takes away the possibility that a complaint or query could be missed by a team member, as it will be right in front of you on the system. With customers demanding a quick service, this form of communication system can see your customer satisfaction stats skyrocket. A quick response can be the difference between a happy customer and a dissatisfied one, after all.

The key points here are: Speed, efficiency and ease of use. There really is small room for error with a Unified Communication system. Your business strategy is designed to help the company move forward, improve and exceed what it was delivering before. Unified Communications could be the key ingredient to your business doing just that.

What is WebRTC? – Overview for Busy People

webrtc, logo, chat, bubble, shapes, colours, colorsNo other topic is roaming the news and social media as much as WebRTC these days. But what is WebRTC and what should it mean to you?

Today I would like to give you an overview around this trend and where it came from. In this article I would like to try out the “For Busy People” article format by consolidating all hot topics into quick facts to add value to you without getting side-tracked. I know you busy people are busy and so you can just skip the parts of the article that you are not interested in.

What does WebRTC stand for?

WebRTC means Web Real-Time Communication, so we are talking about ways to communicate without any delay, based on a web-browser, without the use of software that needs to be installed beforehand.

What is WebRTC?

WebRTC is an open framework for placing real-time communication components on web-pages and is controlled by the World Wide Web Consortium (W3C), who are also taking care of other web-standards such as HTML, XML, CSS and others. WebRTC components could include methods such as VoIP, Instant Messaging (or just “chat”), video conferencing or a combination of these. Personally I would count WebRTC to the umbrella of Unified Communications, but the actual use of the WebRTC solutions depend on each enterprise.

Where does WebRTC come from?

WebRTC technology was first developed by Global IP Solutions (or GIPS), a company founded around 1999 in Sweden. In 2011 GIPS was acquired by Google and the W3C started to work on a standard for WebRTC. Since then Google and other major players in the web-browser market, such as Mozilla and Opera, have been showing great support for WebRTC.

How does WebRTC work?

The framework is based on HTML5 and JavaScript but does not utilise SIP or H.323 like other Unified Communication solutions. The signalling and transfer of data works over RTP and with an XMPP extension called “Jingle”. With the newly introduced JavaScript Session Establishment Protocol (JSEP) direct connections can be established without the need of a piece of hardware in the middle. Depending on the deployment audio, video and / or other data can now be exchanged to allow WebRTC to happen in your browser.

And for our firewall traversal specialists: WebRTC can do STUN, ICE, TURN, RTP-over-TCP and supports proxies. What else do you wish for?

What does WebRTC mean to me?

Imagine the impact of 1,000,000,000+ endpoints. Not bad! This is the potential amount of endpoints talking to each other and making VoIP calls or even video conferences. Even though Microsoft is strongly pushing Skype for desktop video conferencing, they are also making sure that their Internet Explorer is ready to take on the WebRTC challenge.

But the missing link right now is: Will there be interoperability between WebRTC and other Unified Communication solutions? I believe the first developers, making both worlds compatible to each other will have edge.

Examples for WebRTC?

The possibilities are impossible to count. Especially in the age of BYOD everyone has their smartphone always ready and beyond that every notebook and desktop PC could participate in WebRTC. Here are some examples I could think of:

  • Customer service via video conference (the end of the service hotline?)
  • Working together on documents via web (web-collaboration beyond firewalls)
  • Smart-TVs allow you do do video conferences without infrastructure or service running in the back (if there’s a browser – there’s a way!)
  • Not interested in video conferences? Have a video diary! (takes only cloud storage and WebRTC)
  • WebRTC might change the face of Social Media platforms like Facebook, LinkedIn and Twitter completely if implemented (why not quickly talk about it?)
  • Instead of displaying phone numbers to your common window-shopper, provide a QR-code or a NFC space, so users can reach directly to you with their smartphone or tablet (we got a camera, a mic, a speaker – so let’s use them!)

Is there a WebRTC presentation?

You are lucky! Google has recently released a web-based presentation with a lot of interesting slides. I have also added a video below, for your to get some more details on WebRTC, Let me know of your thoughts!

Personal Telepresence – Software Solution Comparison

Telepresence on your desk is a great enhancement to the benefits of video collaboration. It enables you to join meetings ad-hoc and (at least for me) replaced the need for doing a phone call. Even if hardware based endpoints are not available there are software solutions available for personal telepresence.

Throughout 2012 I have been using a hardware-based endpoint for quick communication via video and since January 2013 I switched to a software-based solution. I tried out a few and wanted to share the comparison with you.

In the personal telepresence solution comparison below, I listed several options on personal telepresence software clients or web conferencing solutions with video conferencing functions. You will also find links to each solution further down, in case you would like to get more details on the products.

My requirements

In the comparison we considered most features and functions but to keep it short and sweet, we published only the most popular and relevant ones. For myself I have a strong focus on security and encryption as well as the ability to call all other H.323 based endpoints and infrastructure devices. With the Videoconference24 client for example I am able to call any box no matter if it is from Huawei, LifeSize, Cisco, Radvision / Avaya, Polycom or similar manufacturers. As long a software-client supports standard SIP or H.323 calling those is also possible – you get the idea: I want to reach them all and I want my line secure even through public internet!

Beside that I enjoy the ability to invite for multipoint video conferences without reserving resources on a separate MCU. In most cases this would cost money yet again and like this I can completely cut both the invest in MCUs as well as starting a video call for right now, without booking nor calling anyone to prepare my conference. Of course video conferencing managed services do make sense in many occasions but just for a sudden meeting I don’t need someone on top of things.

Participants of comparison:

There are more solutions than that available and if you would like to add the solution you have good experiences in please feel welcome to let us know in the comment section below. As usually I am more than happy to update the comparison in collaboration with you.

Summary

I am now using the Videoconference24 solution provided by Global Media Services and don’t have a broken heart when I think back to my hardware-based endpoint from last year. Just one thing I would like to add is that when you are saving big-time money going to software-based solutions: Get high-end peripherals for it! You don’t want to be the VGA person in a HD call because you are using the old webcam back from the days. Recommended gear (in my books) comes from makers such as Logitech and Jabra.

What are you using? And … are you happy with it? I want to know your opinion!
