asterisk users - Nov 2008 - How to get correct dial result for outgoing calls thru ISDN?

Hi everyone,

Currectly I'm having some troubles to get correct status of my calls throug
ISDN lines, when outbound calls don't get its destination I always receive
NO ANSWER as ${DIALSTATUS}  despite the fact I know the target number
doesn't exists or is busy at that time.

Maybe there is something I must change in my zaptel.conf or zapata.conf,
current configs follows:

#### *zaptel.conf*
# Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER)
span=1,1,0,ccs,hdb3
# termtype: te
bchan=1-15,17-31
dchan=16

#### *zapata.conf*
 [channels]
language=en
context=default
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=no
threewaycalling=yes
transfer=yes
canpark=no
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
rxgain=0.5
txgain=0.0
immediate=yes
busydetect=yes
busycount=4
busypattern=500,500
answeronpolarityswitch=yes
hanguponpolarityswitch=yes

;*groups*
group=2
context=incoming
immediate=no
switchtype=euroisdn
signalling=pri_cpe
channel=32-46,48-62

#### *extensions.conf*

exten => _9.,n,Dial(Zap/g2/${EXTEN:1})

Asterisk version is: 1.4.21.1 and I'm using a Digium TE420P card to connect
to ISDN.

Thanks in advance,

Use ${HANGUPCAUSE} which provides a Q.931 hangup cause.  chan_sip and 
chan_iax (maybe other channels) translate the protocol specific causes 
to a Q.931 hangup cause.

I would recommend you check the doc directory in the Asterisk source 
code for channelvariables.txt, but for some reason that I can't figure 
out most of those docs where translated into TeX format in 1.6.  Maybe 
the Wiki has a text version.
