        We have done some work on ooh323 and H.264. We can add MPE4G support if 
        needed but this will be a paid work.
        Still I do not understand the need: ig you go through a RADVISION 3G 
        gateway  you will need only H.263 support that. No?
          

Yes that's right, but there is a reasonably significant improvement in video 
quality of you go MPEG-4
Of course h.264 (MPEG4 Level 10) would be the best, but Radvision (AFAIK) do 
not support that.


        I know that H.324m makes the provision of using MPEG4 video as codec 
but 
        I have not seen a single terminal that support it.
          

Nokia 6110, Motorola Razor V-series,  Nokia 6220 etc all support MPEG4.
In fact most of the newer (<3 years) video mobile phones do.

                Hi,
                
                I have built asterisk with video support and ooh323.
                
                Using a Radvision gateway, I can place a 3g call and play video 
using
                h.323 signaling with the h.263 video codec.
                
                ooh323 does not support the mpeg4 codec when it negotiates 
terminal
                endpoint capabilities.
                
                Does anyone know of a way to support the mpeg4 codec with 
asterisk using
                h.323 signaling?
                
                Thanks,
