We are currently unable to make outgoing calls on our ZAP Trunks. When a call is made it rings three times and the call drops. Incoming calls work well.
Outgoing and incoming calls work well on our SIP trunks.
I tried to turn on debugging and verbose logging but no information is received when the problem occurs.
Here are the versions of what we are running:
Linux 2.6.18 (407.el5)
Can someone help with resolving this?
