Eaxctly. Some of the older products like OnLan especially will never support 
H.264... OnLan is really 'Lost to the Sands of Time' anyway. The version ~3+ of 
ViaIP GWs and all current Scopia series GWs will support H.264 by default. 

Hope that helps.

        Hi,
        
        RADVISION products all support H.264.
        

Even the older ones (ViaIP 400 - part no 55580-00001)?

I did capture a trace of an h.323 call setup and only saw H.263 & MPEG4 being 
offered.... but then that's probably because the phone I was testing with only 
supported those 2 codecs.

Might try with a newer phone that supports h.264 and see what I get.

                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,
