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.

In the communications industry, smartphones have evolved into an invaluable device that blurs the line between business and personal processes. Many of the features necessary on these gadgets elevated the status of these devices from merely a trend to an inexpensive ubiquity. With SMS functions, e-mail connectivity, internet browsing, and voice over the internet protocol applications; smart handsets are now key examples of how mobile unified communications translate to a more successful enterprise.

Unified Communications in the Mobile Age

The concept is no longer an innovation or a ground-breaking thought. A 2011 research by Information Week stated that almost 36% of enterprises have been implementing unified communication systems. Back then, almost one in five business technology experts said that deployments of unified communication strategies are under-way. O2 conducted a similar study this year, which showed that 88% of senior IT leaders said that a consolidation of their data, voice, and mobile networks will occur in the next two years. Unified communication is the perfect contingency plan.

There seems to be one reason why so many deem this enterprise concept as a standard. As  ‘smart’ technologies grew in number, innovations related to the communication realm are both inevitable and optimal. The industry enjoys the continually improving technology of VoIP and live video, which equates to web conferencing being the norm on many enterprises. Instant messaging and social networking has largely affected the business way of thinking.

Unified messaging is a concept that allows a single space to become the gate to many different communication portals. All of these technologies are made simple, portable, and hassle-free mobile technologies – smartphones, tablets, and everything in between.

Vital Role in a Business’s Success

Its aim is to address the many common errors committed through traditional business communication models. These communication problems often stem from misunderstandings, Chron said. More often than not, these misunderstandings come from the vagueness of language. Either way, digital unified communication strategies are employed to lessen the risk of these crucial flaws.

A well-planned strategy, zeroing on the mobile platform, can prove to be beneficial to many enterprises through the following advantages:

  •  Maximize productivity – It allows a better exchange between managers and workers, minimizing time wasted through unnecessary back and forth e-mails or calls. Working at home is now a possibility that is open to most desk jobs that previously required office spaces and devices.
  • Minimize costs – It is admittedly not the least expensive resource out there, but it is definitely a guaranteed investment that pays off over time. Also, the initial cost may be reduced depending on the current tech and communication infrastructure of the company and thus, can be modified for cheaper solutions. Additionally, the cost of travel can be minimized (or even totally eliminated) through many features of UC. 

Social Media and Unified Communication

Social media has undergone many advances in its field that is largely due to unified communications. For example, the increase in popularity of social networking site LinkedIn tells us that there is more to social media than ‘liking pages’ and ‘becoming a fan’. This interestingly blurring of professional and personal realms is credited to UC concepts such as network cultivation through contacts. Mark Straton, senior VP of Marketing, Voice and App Solutions of Siemens Enterprise Communications Group, echoed this sentiment. “Social media tools have rapidly moved from being the preferred communication method of millennials,” Straton said.

The main goal of UC is to reduce what is called communication latency. Thus it’s touted better than the multitude of avenues by which we communicate as people, workers, or businesses. This has been adapted extremely well in the most recent phases of social media through sharing of Tweets and automatic posting on Facebook’s wall from many other places like Flickr, Instagram or Ask.Fm.

Summary

It is no surprise that the enterprise unified communication market is rising. In this age of mobile usage, businesses acknowledge the necessity of an equally mobile enterprise to increase yield without much wasting of resources.

Introduction to Session Border Controllers

High definition video conferencing is a standard right now. If it will change, it will only change to an ever higher definition such as Ultra HD (involving 4K and 8K). Virtual workplaces, telecommuting and working from home becomes more and more easy and so organisations go expanding, sometimes forgetting about network requirements ending up with new capacity limits or reduced quality of their video communication solution.

A Session Border Controller can help with many problems there might be, but it is not a remedy for every issue ever to occur on your video conferencing network. I wrote this article to give you some more insight into what a Session Border Controller is, what it does and how it can help your corporate communication.

What is a Session Border Controller?

A Session Border Controller is a network component designed to safely link networks with a different security requirement and setup. They are mostly utilised for VoIP and video conferencing networks to establish secure connection sessions. The Session Border Controller therefore allows control of signaling and transfer of media data in a secure way.

What can I do with a Session Border Controller?

Session management allows service providers to control the session routing, establish interoperability across environments with differentiating standards, enforce bandwidth policies or create an interface to a third party application. To keep it short and simple: A Session Border Controller optimizes solution performance and overall service quality, it allows a rapid service deployment or growth and it protects infrastructure from malicious attacks.

Who develops Session Border Controllers?

Based on Gartner’s Magic Quadrant for Session Border Controllers from October 2012, Acme Packet (recently acquired by Oracle) excels in execution as well as vision scope, making them the leader of the magic quadrant (see graphic). Other competitors are Huawei, Sonus, Genband, Metaswitch Networks, Dialogic, ZTE and Technicolor.

Magic Quadrant for Session Border Controllers by Gartner Research

Acme Packet is very interesting due to their focus on unified communications networks and even offering solutions especially designed for video conference networks of manufacturers such as Alcatel-Lucent, Avaya / Radvision, Cisco (including former Codian / Tandberg technologies), LifeSize, Polycom and Vidyo. Supporting and enabling interworking these technologies the Acme Packet solution avoids potential for vendor lock-in, protecting the investment made in video conferencing infrastructure and endpoints.

What are the technical functions of a Session Border Controller?

The functional scope of a Session Border Controller can vary, depending on what the individual device is designed to do. However to reflect a maximum of capability information, we would like to list the following functions that can be found in Session Border Controllers:

Connectivity

  • IPv4 / IPv6 interworking
  • SIP manipulation
  • NAT traversal
  • VPN connectivity
  • H.323 / SIP interworking

Quality of Service (QoS)

  • Traffic policies
  • Call admission control
  • ToS / DSCP bit setting
  • Resource allocation
  • Rate limiting

Security

  • Defense against DoS attacks
  • Can prevent toll fraud
  • No topology hiding possible
  • Malformed packet protection

  • Business Intelligence, reporting, management information, source for billing information

Summary

Even though not a mandatory part for VoIP or video conferencing networks, Session Border Controllers have a great potential to add value to the communication services of organisations. The relevance increases for service providers companies as the functions described above can significantly increase the quality and performance of a serviced network.

Telepresence Technology Connect Remote Employees

The benefits of working in a home office and using telepresence from the perspective of the employee.

Seven years ago, I was pregnant with my son when my husband decided that it was imperative for me to find a job. At the time, I couldn’t imagine leaving my baby to go to work, and so I decided that even if it made my job search an arduous one, I would hold out for the opportunity to work from home.

I was lucky, and within a month or so, I was offered a web content writing position with a tiny, semi-local internet marketing firm. The manager wanted me to come in for weekly meetings, but preferred for me to do the rest of my work from a home office. The company was only occupying a small space at the time, and finding a place for me to work there would have been a difficult feat, so I was able to sign on for the remote work I wanted without inconveniencing my new employer. I was thrilled.

When this …

The Early Stages

In the beginning, I had a lot of questions, and finding useful ways to stay in touch with my supervisor led me to investigate affordable video conferencing options. Often, I felt as though it would be easier for me to do my job if I could still see and interact with my co-workers as if they were right there in my home. We tried Skype and other free services, but eventually I began doing more work with clients, the company grew, and our sales team expanded. At that point, it became worthwhile to research and employ more advanced telepresence solutions both at home and in the office.

When my employer presented me with what seemed like a giant monitor and camera set up, I was initially uncomfortable. It wasn’t life-sized, but it was much more intimidating than popping up on his 13” laptop screen when we needed to work on a project. Still, the possibilities for collaboration were endless.

Afterwards

I used multipoint video conferencing from my home on the East Coast to present information to clients in California. When a new customer was having trouble understanding our service, I set up my HD video conferencing equipment, and used a white board and my computer screen to walk them through the process. Technology connected me to meetings, sales events, and significant opportunities, all from the comfort of my own home. It was an ideal way to work, especially with young children in the house.

As more and more companies begin seeking out talented employees while paying less mind to their location, the video conferencing industry has taken massive steps forward in connectivity, user-friendly operations, mobility, definition, and more. Remote workers are signing in from tablets, mobile phones, and advanced equipment alike, all in an attempt to stay close and connected while doing their jobs from afar. Some, like myself, are parents who need to be at home for their children. Others are simply located at a great distance from the businesses that can most benefit from their services. Many are freelancers, but many more are doing full-time work for large and small corporations.

The Future has Arrived

Telepresence solutions are increasing in affordability and quality as well, and as they do, I predict that more offices will shut down. Start-ups and small businesses will cut costs by eliminating monthly rent and allowing their employees to connect from home. This is the sort of technology that, when used correctly, can attract a wider base of clients and pull staff from the widest possible pool of talented individuals. Video conferencing isn’t just a high tech toy these days – it’s a real solution that can help businesses grow their bottom lines while also contributing to employee satisfaction, and it’s just another indication that the future we dreamed about years ago is finally here!
