[asterisk-users] DAHDI congestion problem

[Andy Howell]

I am unable to dial out over a Wildcard TDM400P. This was working previously, so must have 
messed up the config somehow. I'm running Asterisk 1.6.0.15, with FreePBX 2.5.2.2.

When I dial, I see:

   -- Executing [s at macro-dialout-trunk:19] Dial("DAHDI/1-1", "DAHDI/g0/9239220,300,") in 
new stack
   == Everyone is busy/congested at this time (1:0/1/0)

It looks like the group is valid:

dahdi show channels group g0
    Chan Extension  Context         Language   MOH Interpret        Blocked    State
       4            from-zaptel     en         default                         In Service


The only Warning or Error I see is when asterisk first starts a new call.

  logger.c:     -- Starting simple switch on 'DAHDI/1-1'
[Sep 27 15:55:50] WARNING[4199] chan_dahdi.c: Unable to enable echo cancellation on 
channel 1 (No such device)

On my TDM400P card, channel 1 is my analog phone, 2 my fax, and 4 the POTS line.

More config files etc below. Any ideas?

Thanks,

	Andy
