I suspect that is caused by asterisk not knowing about your video codecs
(I have never done video over IP myself, so just a guess).

If your devices talk to each other,
#   device <=> device
they can use all the codecs both of them know

As soon as asterisk is involved,
#   device <=> asterisk <=> device
the codec negotiation goes through asterisk. So asterisk must at least
_know_ the codec that those devices want to use.

I think I saw some info about that in the www.voip-wiki.org
