[asterisk-users] Asterisk not picking up (some) calls due to zaptel detecting and clearing alarms

[Gonzalo Servat]

Hi All,

For the most part, the PBX works as it should. Occasionally people complain
that they call and the PBX doesn't pick up. Other times it looks like the
call is answered by Asterisk but I still hear ringing and I start listening
to the IVR menu a few seconds into it.

As for Asterisk not picking up, I see the following in the logs:

[Mar 27 13:32:29] NOTICE[13197]: chan_zap.c:7071 ss_thread: Got event 18
(Ring Begin)...
[Mar 27 13:32:30] NOTICE[13197]: chan_zap.c:7071 ss_thread: Got event 2
(Ring/Answered)...
    -- Executing [s at incoming:1] Answer("Zap/2-1", "") in new stack
    -- Executing [s at incoming:2] Wait("Zap/2-1", "1") in new stack
[Mar 27 13:32:30] WARNING[13197]: chan_zap.c:4203 get_alarms: Unable to
determine alarm on channel 2
[Mar 27 13:32:30] WARNING[13197]: chan_zap.c:4424 zt_handle_event: Detected
alarm on channel 2: No Alarm
  == Spawn extension (incoming, s, 2) exited non-zero on 'Zap/2-1'
    -- Hungup 'Zap/2-1'
[Mar 27 13:32:31] NOTICE[13197]: chan_zap.c:7514 handle_init_event: Alarm
cleared on channel 2

The above messages repeat themselves a number of times as the ringing
continues and causes Asterisk to try and pick up the call again (and fails
with the alarm thrown which then gets cleared).

Any suggestions??

I'm using Asterisk 1.6.0-beta4 and Zaptel 1.4.9.2.

Thanks in advance!
Gonzalo
