[Freeswitch-users] FreeSwitch and Yealink

[Paul]

I'm gonna try all of your guys' suggestions. 

Ivan, I do not think its codec related, I made /log 11 and siptrace on 
all profiles (internal/external) as well as pcap capture of the phone 
itself. For some strange reason the moment the PBX send a packe tot ye 
Yealink phone that the remote party picked up and the call should be 
bridges, the Yealink phone replies with a BYE packet, I'm thinking it 
might be a bug in the Yealink firmware, so needless to say I have 
gotten a hold of their support and opened a ticket, see if something 
comes of that, but meanwhile going to try some of the suggestions in 
this thread and see if I can get any close to work around.
