Analysis for missing SIP video

[jolouis]

Do a PCAP trace on the phone. Instructions are on the main sticky page of the forums under how to diagnose/report problems to Yealink.

Once you have a PCAP, you can use something like Wireshark to open up the file and observer the SIP packets being sent back and forth to see if the Invite includes video offerings.

Typically the two most common reasons for it not working are a) No PBX support (if you're using a PBX then usually it must be capable of passing/signalling to the two end points that they both support video and can talk to each other) or b) mismatched video codecs.
