[Asterisk-Users] Zap and call pickup -- it don't work.

[Andrew Kohlsmith]

The problem:   T100P connected to an Adit600.  Channel 1-16 are FXS, 17-24 
FXO.  I have Zap/24 in callgroup 3 and Zap/1-16 in pickupgroup 3.  When a 
call comes in on Zap/24 I cannot pick it up with *8 from Zap/1-16.

*CLI> show version
Asterisk CVS-04/27/04-23:48:08 built by root at tuck on a i686 running Linux

The zapata.conf and extensions.conf are located here:
http://lists.digium.com/pipermail/asterisk-users/2004-May/048527.html

(I've since changed channel 1-16's pickupgroup to just 3, it didn't help.)

What I see in *'s debug log:

Now you'll see the "No call pickup possible" -- that comes from both 
res_parking's ast_call_pickup() and also from chan_zap.  Basically you get 
that if the channel you're trying to pick up is NOT in AST_STATE_RING or 
AST_STATE_RINGING.

I modified chan_zap.c so that "zap show channels" gives me the state of the 
channel as well.

On to the main event: the CLI log when run as "asterisk -vvvvgc":

Asterisk Ready.

As you can see, Zap/24-1 is *clearly* in AST_STATE_RING.  The only weirdness I 
see is that the hookstate is "off hook" -- I did NOT Answer() the call, and 
my * box at home did not answer the call.  My extensions.conf file looks like 
this:

[in_1234567]
exten => s,1,NoOp(${DATETIME} ${CALLERID})
exten => s,2,System(/usr/bin/perl /usr/local/scripts/astbot.pl '${CALLERID}')
exten => s,3,Dial(IAX2/benshaw at ak_home/s,20,Ttr)
;exten => s,4,Dial(${FXOTRUNK}/${CELL},,Ttr)
exten => s,5,Hangup
exten => h,1,Hangup
exten => t,1,Hangup

I Dial() my home box, and it rings the FXS interfaces connected to it.  Since 
there's nobody home, there's nobody to answer.  My cat isn't that well 
trained yet.  :-)

Can anyone *please* help?  I'm tearing out my hair here, this *should* work!

Andrew
