Did you already sign up for GSMA world congress in Barcelona 15-18 February 2010? Let’s meet: http://www.mobileworldcongress.com

You may have noticed the special ONE site about the 3G-H324M module for Asterisk – sip.fontventa.com – shows an error message for a couple of days. Thanks to the good people at archive.org you can still access an 2008 version of sip.fontventa.com (as far as I know, nothing has changed since then) by using this link http://web.archive.org/web/20080324183826/http://sip.fontventa.com/

Does anybody has a link to the source code of the 3G-324M module for asterisk?

Video call set-up times are generally between 1 to 5 seconds (1-second call set-up when using MONA specified in H.324 Annex K.) independently of the IVVR (Interactive Voice & Video Response) application one is going to use, which is sometimes faster than the initialisation process of complex J2ME (Java 2 Micro Edition) applications. This makes quick on-the-go lookup or entry of information pleasant. However, what happens when the caller needs to interrupt a gaming session or the call is interrupted because of missing network coverage or exceeded battery life? Games should enable users to start and stop with breaks in between, since the time they have to spend may be brief. Mobile games are used especially to pass time for just a couple of minutes or even seconds when waiting for the bus, riding the subway, or to relieve boredom during TV commercials. Therefore, all mobile applications need to apply ways to interrupt a session and quickly resume to the last state as the user desires. This requirement also applies to IVVR applications. As application and user data of IVVR programs can be completely stored on the server-side, there are no limitations to auto-save program states or record the user

In desktop video conferencing, the video conferencing application is normally bundled to an Instant Messaging software that includes text chat capabilities. Users can appoint or prearrange a video conference using textual chat. In contrast, the current evolution of video telephony in UMTS (Universal Mobile Telecommunications System) networks based on the circuit-switched 3G-324M service does not seamlessly combine video conferencing with other communication channels. The notion of video telephony in the mobile environment is nearer to standard voice calling than in the stationary world. Therefore, it is more likely that somebody will place a video call without prior announcement. This leads to privacy and inconvenience concerns. The callee might not want to be seen during a conversation for a variety reasons: A video call

Even with a great deal of marketing, early attempts to convert users to the video telephony technology flopped (Jones and Marsden). In contrast, desktop video conferencing is incredibly popular for private person-to-person conversations and widely used for video conferencing in business environments such as telepresence for computer-supported cooperative work (CSCW).

In desktop video conferencing scenarios, typically a stationary computer is used. Camera and microphone are fixed and usually maintain the same distance from the person participating during the conversation. Moreover, lighting conditions are generally better than
