[Freeswitch-users] FreeSwitch and Yealink

[Mario G]

I have had zero FreeSwitch problems with the T32 (18 months now) and new T46 but I don't use OpenVPN. Try Yealink tech support, they have been great and fast at fixing issues (rings, dimmer, etc.) for me, usually less than a week. BTW, the phone have great logging and pcap built in, I would test and send that to Yealink.

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.

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.
