[Freeswitch-users] FS to a Sonus SIP trunk

[Yehavi Bourvine]

Hello Micha,

  How much time does it take until the sound is choppy?
We have been connected to Sonus provider up to a week ago. Incoming calls
started being choppy after about 15 minutes (outgoing calls were ok). We
also had inconsistent problems with DTMF. We ended it by changing a
supplier...
