Another mystery for the list, hopefully someone has ideas on a fix... :) I've got an Asterisk 1.8.12.0 system connected to a CAS T1 (ESF/B8ZS, fractional 1-8). Outbound dialing works correctly, but while the call is in progress, there is no 'ringing' heard by the end user. So, on a SIP phone connected to this system, I dial a number, that call goes out DAHDI via the CAS T1, and the remote side is actually ringing (my cell phone for example), but the SIP phone remains silent. If I answer my cell phone, full 2-way audio is present.
The telco has already enabled ringback on the circuit but that has not had any effect on the operation. Any thoughts on how to proceed? Here are the pertinent parts of the debug log showing the events on the circuit when dialing: [Jul 27 11:31:20] VERBOSE[14199] app_dial.c: -- Called DAHDI/g1/XXXYYYY [Jul 27 11:31:20] DEBUG[14149] devicestate.c: No provider found, checking channel drivers for DAHDI - 1 [Jul 27 11:31:20] DEBUG[14149] devicestate.c: Changing state for DAHDI/1 - state 2 (In use) [Jul 27 11:31:20] DEBUG[14149] devicestate.c: device 'DAHDI/1' state '2' [Jul 27 11:31:20] DEBUG[14190] app_queue.c: Device 'DAHDI/1' changed to state '2' (In use) but we don't care because they're not a member of any queue.
