3G-324M can be found in over 450 million handsets worldwide. A software based protocol stack that is needed in every 3G handset, 3G-324M, however, has absolutely zero open source implementation? Because it is not IP based. Commercial value The open source model succeeds; not because people want to contribute and invest their time in free software; it is because corporations are finding a way to support such investments by getting their revenues indirectly - by selling maintenance, services, training, advertising

Last week, Paul Jones explained on VoIP Survivor the basic concepts behind AMS. The name might ring a bell to those familiar with IMS, but there is no real connection (besides the unfortunate use of a similar acronym). While IMS is an ongoing work, AMS is just beginning. There are many people out there engaged today in one way or another with IMS. They come from different companies and participate in various organizations

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

There are times when de-facto standards hinder the adoption and use of services. This is the case with 3G-324M and video ring-back servers. What’s 3G-324M? 3G video telephony uses a protocol called 3G-324M. This protocol in turn, uses another protocol called H.245 for call control - with H.245, handsets signal what features and capabilities they have and negotiate the media channels that will be used in the call. H.245 includes procedures and message that allow for the opening and closing

When you work with standards it is hard to differentiate. Take for example the browser market. Not all browsers are created equal. Taking a look at the 4 major browsers on the market today, and trying to summarize each one in a sentence, this is what you will get: Internet Explorer - Largest “customer base”, not adhering to standards Firefox - Full of plugins, liked by developers and

I read a while ago an opinion stating that there is no need anymore for standards - people choose their proprietary way of communication by installing a given application on their desktop or mobile device - be it Skype or one of the other services out there. I disagree with this view. Proprietary solutions definitely have room in our world. If you take telecommunication, the first thing that comes to mind is Skype. They are based on a proprietary protocol,
