[Freeswitch-users] FreeSwitch and Yealink

[Ivan]

You have to set the variable in the dialplan, before bridging. You can 
also set it directly in the bridge command.

More details at:

But the only way to really know what is going on is to enable siptrace 
on your sofia profile and see what is offered before your endpoint 
hangups (if you post your debug, please post on freeswitch's pastebin).
