[asterisk-users] Can't get video on one server of 4

[Administrator TOOTAI]

Hi,

we have 4 asterisk, versions are 1.4.35 1.4.36 1.6.2.18 and 1.4.42 One 
GrandStream GXV3000 is used for the tests. He is registered to asterisk 
1.6.2.18 asa well as 1.4.35. Calling echo test is OK on both servers, 
get audio and video. Calling echo test from asterisk 1.4.36 bye a SIP 
trunk from both others servers is also working well.

What fail, is video on echo test from asterisk 1.4.42 using SIP trunks: 
we have audio but no videobeside the fact that video codec are 
negociated as shown below.

All servers are on public IP. Here is a debug from a call from server 
running 1.4.35 asterisk to the 1.4.42 one:

All trunks. are setted from the same manier:

[trunk]
;
type=peer
deny=0.0.0.0/0.0.0.0
permit=XXX.XXX.XXX.XXX
host=host.domain.com
context=from-trunk
disallow=all
allow=all

A "sip show peer <mypeer>" show that video is on.

What can be the problem, I start loose my hairs!

Thanks for any hint.
