[asterisk-users] Call not going through and failing because "never answered"

[Andy Beak]

Hi,

I'm trying to use Asterisk to place Automated Voice Calls.

A verbose log from Asterisk CLI taken when I place a call in the spool 
directory looks like this:

     -- Attempting call on SIP/MTN-NEW/my-number for application 
MP3Player(/myfile) (Retry 1)
   == Using SIP RTP CoS mark 5
 > Channel SIP/MTN-NEW-00000005 was never answered.
[Jul 20 10:52:11] NOTICE[14580]: pbx_spool.c:339 attempt_thread: Call 
failed to go through, reason (8) Congestion (circuits busy)

My sip.conf looks like this:

[MTN-NEW]
host=192.168.34.1
disallow=all
allow=ilbc
allow=gsm
allow=g729
allow=g723
allow=ulaw
allow=g729
type=peer

My SIP provider says that no traffic is picked up at their SBC or on the 
WAN gateway port assigned to us.

I've just done a fresh reinstall of Asterisk and am using sample 
configurations for all other conf files.  I am using an open source g729 
codec and have tried shuffling the gsm up above it in case it doesn't 
work properly (to no avail).

Can anybody help me on this?  My boss is breathing down my neck and I've 
never worked with Asterisk before.

Thanks,
  Andy
