<font face="Arial">Hi folks,<br>
<br>
I've made a video call from a SIP softphone to a PBX ACD queue
that was bridged by FS.<br>
I set the PBX(AASTRA) as a gateway in FS.<br>
Here is the scenario.<br>
Softphone --> FS --> PBX --> IVR<br>
|--->
Agent SIP phone<br>
The call can be established with no video.<br>
<br>
If I make the call bypass FS like this:<br>
Softphone --> PBX --> IVR<br>
|---> Agent SIP
phone <br>
<br>
The video call can be make successfully.<br>
<br>
All these device are all behind NAT.<br>
I set the parameters renegotiate-codec-on-reinvite=true,
inbound-late-negotiation=true and still no video.<br>
I can't figure out why the video missed.<br>
<br>
Here is the FS siptrace.<br>
