Video support not working



I am using CVS Head, I have two Innomedia video phones, if I get them to register to asterisk I have no video support. if I register to SER (on the same box) the video works fine.

I have the video support=yes in sip.cof
as well as the allow= h261 and allow=h263 for each video phone.

any ideas?


What model are the phones?


Innomedia MTA 3368
