asterisk users - Oct 2007 - Unable to dial out over Zap - span 1 got hangup, cause 44

Hi

I posted earlier about having issues connecting to Telewest's ISDN,
only to find out later Telewest had forgotten to turn it on -
hopefully I'm not having a similar silly problem.

My PRI span is now up and operational, but when I try to send a call
out over it, I just get congestion tones. Occasionally, I get about
one second of ring tones, only for it to cut out and play congestion.

Here's a bit of output (I've taken out the phone number)
    -- Executing [s at macro-dialexternal:6]
Dial("SIP/charlie59-082bc890", "Zap/<my phone
number>|3600") in new
stack
    -- Requested transfer capability: 0x00 - SPEECH
    -- Called g0/<my phone number>
    -- Channel 0/4, span 1 got hangup, cause 44
    -- Forcing restart of channel 0/4 on span 1 since channel reported in use
    -- Hungup 'Zap/4-1'
[Oct 25 17:35:22] NOTICE[20503]: cdr.c:434 ast_cdr_free: CDR on
channel 'Zap/4-1' not posted
  == Everyone is busy/congested at this time (1:0/0/1)

Additionally, once a zap channel has been used like this, it seems to
end up in stuck in this state:
PRI Flags: Resetting

Previously, someone mentioned that the TE110P card installed had a few
issues and I should be using a TE120P instead - could that be the
cause?

Thanks

Dave

If your span is up ok, and you are actually getting a valid cause code 
back (as you mentioned) your card should be just fine.  It sounds like 
protocol related problems.  Are you sure you are sending the correct 
digit format out on the line?  PRIs can be very picky about it.  Some 
like the area code, some don't, and a number of other things.  Also, can 
you get an inbound call on the PRI?  That's usually the easiest first 
case to get working.

 From looking at the specs, it looks like 44 is cause "requested channel 
unavailable".  Maybe they haven't unbusied the channels yet or
something
like that.

Oh yeah, and could you also post a "pri debug span x" of the call as 
well?  That should tell a lot too.
