[Freeswitch-users] FreeSwitch and Yealink

[Paul]

Hi guys,

Has anyone had any issues using FreeSwitch with Yealink phones? My 
phones connect to FS via openvpn tunnel. All incoming calls work no 
problem, call comes through phones ring everyone can hear each other no 
issues, having a very strange issue though on the outgoing calls. As 
soon as the destination party picks up (this external calls) the call 
hangs up.

short FS LOG:

switch_ivr_bridge.c:475 Channel [sofia/internal/105 at 10.0.0.34] has been 
answered
sofia.c:6528 Hangup sofia/internal/105 at 10.0.0.34 [CS_EXECUTE] 
[ORIGINATOR_CANCEL]
switch_ivr_bridge.c:721 Hangup sofia/external/2503004900 
[CS_EXCHANGE_MEDIA] [NORMAL_CLEARING] 

So FS thinks the phone sent a BYE packet (which I can see with 
siptrace) but the phone's timer keeps going as if it thinks the call is 
supposed to keep going.

Internal extension to extension works fine (even if the extensions are 
at a different physical location and subnet).

I setup a second account to one of my asterisk servers and 
outgoing/incoming work just fine, so it seems this strange combination 
of FS and Yealink ... does it on 2 models T32G and T38G (only phones I 
have).

I have updated firwmare to their latest version (which in the comments 
say freeswitch ready)

Wondering if anyone else had any experience with these, or has some 
thoughts?

Thanks

Paul
