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.

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

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.

Meetings in the 4th Dimension


Shanghai, Frankfurt or Chicago: Global teams meet each other in person only occasionally. Many staff members work from different locations. To enable collaboration, remote solutions need to be used.

Meetings with dispersed participants can be challenging. Solutions that help meetings function as if all participants are in the same room, significantly determine how far you can avoid misunderstandings and achieve your business goals.

Companies are increasingly using audio and video conferencing for professional collaboration. Some of them even go one step further and share their desktops allowing the team to view PowerPoint, Excel and other files. Regardless of high-quality equipment, remote meetings can end up being more or less passive in nature. What’s the reason for this? There is something missing, which plays an essential role in traditional face-to-face meetings; the ability for everyone to be engaged in the process of developing ideas and content by collaborating and writing on one common surface.

SRS

This visual aspect to virtual meetings increases productivity and leads to better results.

Imagine if the Product Manager in Shanghai annotates on a document someone shared on a screen. He presents an idea and quickly drafts a chart. His peer from Frankfurt picks up the idea adds some remarks in hand writing and explains via video which barriers need to be overcome to successfully implement the idea. Without long explanations and sending files back and forth, everybody immediately understands the ideas their colleagues are presenting. The visually edited document can be sent with a single click and becomes a working file that reflects the team’s collaborative work.

In the fourth dimension of collaboration teams are surpassing what they would normally achieve in a dispersed collaboration environment. All participants experience being an integral part of the meeting, just as if they were all on-site. Interacting with ideas, strategies and concepts from no matter where you are highly encourages teamwork and reveals aspects which otherwise would not have become visible. This kind of active engagement and rich interactivity leads to effective meetings, that inspire a new level of collaboration.

How Video Conferencing Technology Can And Is Changing Marketing On The Internet

Video conferencing, once the domain of larger organizations with bigger budgets, has come down in price dramatically during the last decade and a half. At the same time, not only its quality but also its versatility and portability have increased exponentially. The end result (at least up to now) of these trends has been a dramatic explosion in how many people use video calling and the ways in which they do so.

Aside from the many coordination and communication benefits that have stemmed from the video calling revolution, another major bonus has also been discovered in the myriad ways by which this rapidly advancing technology can be used to serve as a marketing and promotional tool for not only large companies but also smaller business and even individuals following their own business or professional goals.

From personalizing customer relations in an effort to draw in more sales to using video calling for online sales pitches and demonstrations of products or services, video conferencing has become a powerful marketing tool that carries its own unique position in the online promotion landscape.

Here’s a look at some of the major innovations found in using video conference call technology when marketing to clients, buyers and anyone else.

More Face-to-Face Client / Seller Relations

The first and most obvious marketing innovation of video calling is the ability it has given marketers to engage their clients and buyers in face-to-face consultations or Q&A periods.

If someone is running a service or product business on the web, making sure to highlight the fact that their customers can interact with real people in real-time over any questions, doubts or issues they might have before or after buying is a big selling point to many potential clients, especially if their previous experience with customer service in a particular niche involves being ignored or unable to reach some solid customer support.

Whether you’re selling a product or a service, if you really want to enhance your customers experience and decision-making into something that’s memorable, be sure to do exactly this and underscore it in your marketing materials now that video conferencing offers you the ability to schedule actual life Q&A sessions with multiple people over interactive video media.

Interactive Long Distance Pitches

The long-used art of pitching a product, service or idea to potential buyers during a face-to-face meeting is a tried and true marketing tactic that numerous business owners use worldwide. With video conferencing, this very same strategy can reach into the digital world by allowing a marketer to lure clients or potential buyers toward a one on one consultation which is then in essence used as a sort of digital pitch that tries to create a purchase through interactive salesmanship.

Although this tactic might have some implementation difficulties that stem from problems with getting people to actually sit down for the sales meeting, if you’ve already built strong interest in your leads through a sales funnel and have motivated them with some sort of freebie into actually listening to your video call, you could really create a door-to-door sales level of interaction with a completely digital and much more targeted audience. Video call based pitching would be especially effective for high priced products or services that offset time costs even if your eventual sales closing numbers are low.

 Online Seminars through Video Conferencing

This is a really major and still largely unexplored region of the online marketing landscape that could benefit immensely from video conferencing. While physical sales seminars are a common thing in just about every hotel conference room you’ve ever passed through, and online video “webinars” where you can listen in but not participate are already completely established as part of online marketing strategy, a major and still very undeveloped leap would involve joining the two into a completely digital, massive video conference style seminar with full interactivity.

Thanks to the rapidly developing technology of video conferencing, the attendees can interact with the sales presenter just like they would be able to if they had physically gone to a real sales conference while enjoying the convenience of joining in from home as people do with classical online marketing webinars. On top of that there are many consumption based video conferencing software solutions that allow the use of the technology even with a smaller budget.

The marketing benefits this can potentially offer your business are considerable. For one thing, you as a marketer would save on the high costs of arranging for a sales seminar in an actual location where you’ll have to pay rent and present printed promotional materials. And furthermore, you could duplicate everything available at live sales seminars in an online environment while still being able to take questions and speak to leads in real-time. A somewhat heavier telepresence software bundle would be needed to pull off this kind of online marketing maneuver, but the potential benefit could be completely worthwhile.
