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.

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,
Andy
