<P><FONT SIZE=2>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.<BR>
<BR>
Hope that helps.<BR>

Hi,<BR>
<BR>
RADVISION products all support H.264.<BR>
<BR>
<BR>
Even the older ones (ViaIP 400 - part no 55580-00001)?<BR>
<BR>
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.<BR>
<BR>
Might try with a newer phone that supports h.264 and see what I get.<BR>

We have done some work on ooh323 and H.264. We can add MPE4G support if<BR>
needed but this will be a paid work.<BR>
Still I do not understand the need: ig you go through a RADVISION 3G<BR>
gateway you will need only H.263 support that. No?<BR>
<BR>
<BR>
Yes that's right, but there is a reasonably significant improvement in video quality of you go MPEG-4<BR>
Of course h.264 (MPEG4 Level 10) would be the best, but Radvision (AFAIK) do not support that.<BR>
<BR>
<BR>
I know that H.324m makes the provision of using MPEG4 video as codec but<BR>
I have not seen a single terminal that support it.<BR>
<BR>
<BR>
Nokia 6110, Motorola Razor V-series, Nokia 6220 etc all support MPEG4.<BR>
In fact most of the newer (<3 years) video mobile phones do.<BR>

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