[Asterisk-Users] FXO card still won't pick up...

[Matt Lawson]

I recently updated (fresh checkout) to the newest zaptel and Asterisk. 
 The one I was using before was a couple of months old.

After updating, my zap channels don't work.  They won't pick up incoming 
calls or dial out.  When I try to dial out I get:

    -- Executing Dial("SIP/3064-564c", "Zap/g1/ww954.......") in new stack
NOTICE[245776]: File app_dial.c, Line 698 (dial_exec): Unable to create 
channel of type 'Zap'
  == Everyone is busy at this time

When I try to call in, usually nothing happens.  One time it answered 
and Asterisk acted like it was going through the dial plan steps, but on 
the phone I never heard anything.  It just hung up immediately.  After a 
couple more seconds Asterisk noticed the hangup and stopped its dial plan.

chan_zap.so loads OK, and I can do this:

*CLI> zap show channels
Chan. Num. Extension  Context    Language   MusicOnH
  1            incoming31 en
  2            incoming31 en

Here's an exceprt from when Asterisk starts:

======================


Channel map:

Channel 01: FXS Kewlstart (Default) (Slaves: 01)
Channel 02: FXS Kewlstart (Default) (Slaves: 02)

2 channels configured.


Zaptel.conf is blank.  Zapata.conf follows.  These were the same way 
when the older version was working:

# cat zapata.conf
[channels]
echocancelwhenbridged=yes
echocancel=yes
stripmsd=1
callerid=asreceived
language=en
context=incoming3121
signalling=fxs_ks
rxgain=3.0
txgain=0.0
usecallerid=yes
group=1
channel=1


echocancelwhenbridged=yes
echocancel=yes
stripmsd=1
usecallerid=no
callwaiting=no
callerid="intercom" <9876543210>
context=incoming3130
language=en
signalling=fxs_ks
group=1
channel=2


So, I'm wondering.

1.  What other diagnostic steps can I do to narrow this down?
2.  What flags/switches in Asterisk or Zaptel could be causing this, 
particularly if they've changed recently?
3.  Is there a 'how to diagnose zap problems' guide anywhere?

Thanks.
