Two weeks ago, RADVISION hosted the IMTC SuperOp! 2008 event. The most obvious conclusion from this event is that multimedia conferencing (or should I say Unified Communications) is getting better – at least in terms of interoperability. Without exceptions, all companies successfully connected video sessions with one another. The IMTC SuperOp! event is the main interoperability event of the IMTC. In this event multiple activity groups, each dealing with a different multimedia communications technology, gather in a single room to

It has been rumored that the new 3G iPhone features a front facing camera. Assuming this is true, the camera will be used for video calling. An important question is what protocol will be used for the video calls? I have written a guest post at Smith on VoIP blog regarding the difference between 3G-324M and SIP regarding mobile video telephony. In that post I explained that currently mobile video telephony (on handsets) is made possible using 3G-324M. SIP, on

[The ITU have started working on a standard called the Advanced Multimedia System, or AMS. It is a communications protocol intended to solve some of the issues that plague today’s protocols and also enable functionality that is not easily achievable with current systems. I have asked Paul Jones, the rapporteur for the AMS expert group to provide some of his insights on this “standard under construction.”]One of the exciting things about the technology industry is that technology is constantly changing

Once a year, RADVISION’s TBU division holds a road-show in Asia Pacific. In these events, we travel between different countries, meeting clients and holding seminars. Our road-show for 2008 starts today. Seminar in Taipei during the 2007 road-show Now, that the IMTC SuperOp 2008 event is over, it is time to look forward on what will happen in the next two weeks. The road-show is a very exhausting event - it spans four different countries, usually in less than two weeks. In each country, besides the frantic runs from one meeting to another there is a seminar. During the seminar we present the various market needs of the industry along with our solutions - all this is “seasoned” with live demonstrations. This year’s theme is “Development for innovative multimedia application for IMS/NGN”, in which we cover market trends, relevant protocol stacks, client and server frameworks and testing tools. The seminar is relevant for companies who are developing VoIP communication products. In the next two weeks, we will be traveling around Asia, with countries such as Japan, China, Korea and Taiwan on our tour this time. If you are around, you are hereby invited. Just drop me a message.

Security is always overlooked when it comes to VoIP. There are those who feel that security is essential and others who think security is overrated. The truth lies somewhere in the middle. If we need security, we need to decide against what.Here are 4 of the biggest threats in the world of VoIP where it comes to security - this is why we really need to take a good hard look at how we deploy our networks. 1.

[The IP based services such as VoIP (with or without IMS) run over open IP networks. As such, they are susceptible to security threats similar to those in the Internet. As VoIP communications becomes widely used, the security level on it becomes essential. In this guest post, Rasa Siegberg a Senior Systems Engineer from SafeNet provides his insights to VoIP and security.] The Great IP Migration The venerable voice communications industry is undergoing one of the most significant evolutionary steps

A lot of reviews have been done on Office 2007 - this is not going to be one of them. I just had the questionable opportunity of working with Microsoft Office 2007. It can be a very frustrating experience to anyone used to previous Office versions. Office 2007 can serve as a great lesson on how to plan new versions - especially when the customers are engineers. Our company has just migrated to Office 2007 this week. It has

The IMTC’s SuperOp! event is just across the corner, and this time, I am proud to say that RADVISION will be hosting it (pdf). Companies coming to this event will be testing their products for interoperability. There are parts of the market though, that are ignoring interoperability. From my own experience, they pay dearly for it in due time. Interoperability can be viewed as a process where you hurtle your product against a product of a different vendor and
