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