Hi,
We're experiencing an issue with outgoing calls providing two ringing tones on outbound calls with one particular SIP Provider (Gamma Telecom). The connection is otherwise fine and once the destination phone is picked up, both rings silence. We have tried removing the "r" from dialplan options as explained in another post on here with similar symptoms, but this has no effect. Connections via sip to a Cisco ISDN gateway function fine on the same box for incoming/outgoing.
If anyone can offer any assistance with this, it would be much appreciated.
