Hi All,
I have installed a Digium TE110P card on an Asterisk 1.2.1 system. Its connected
directly to the PSTN. But I am unable to make outbound calls on the zap
channels. The light on the card is green. Asterisk CLI shows all 24 channels
when I give the command 'zap show channels'. I also noticed that
Asterisk CLI shows an incoming call every few seconds on the 24th channel. This
must be some kind of a timing signal. This is he first time I am configuring a
T1 so I must have done something wrong I guess.
These are the commands I used to load the zap module:
modprobe zaptel
modprobe wcte11xp
ztcfg -vvv
---------------------------
my zaptel.conf is as follows:
span=1,1,0,esf,b8zs
e&m=1-24
loadzone = us
defaultzone=us
--------------------------
the zapata.conf is as follows:
[trunkgroups]
[channels]
group=1
language=en
signalling=em_w
usecallerid=yes
callerid=asreceived
context=default
echocancel=64
echocancelwhenbridged=yes
rxgain=1.0
txgain=1.0
channel => 1-2
group=2
language=en
signalling=em_w
usecallerid=yes
callerid=asreceived
context=default
echocancel=64
echocancelwhenbridged=yes
rxgain=1.0
txgain=1.0
channel => 3-24
----------------------------------
In extensions.conf i have specified the following line:
[default]
exten => _ZXXXXXXXXX,1,Dial(zap/g1/${EXTEN},15,tr)
----------------------
When I try to dial using the T1 line I get the following error :
Feb 24 06:56:53 NOTICE[5724]: app_dial.c:1010 dial_exec_full: Unable to create
channel of type 'Zap' (cause 0 - Unknown)
== Everyone is busy/congested at this time (1:0/0/1)
== Auto fallthrough, channel 'SIP/7180-a103' status is
'CHANUNAVAIL'
Any ideas guys?
Thanks and regards,
Nitin Joshi.

Also, I would strongly suggest moving to 1.2.4 Doug

How about zap show channel 1 in the CLI? -Brian -------------- next part -------------- An HTML attachment was scrubbed...

A PRI is a service that runs on top of a T1, that is, it uses all 24 channels, but it uses a specific channel (usually the 24th channel) for signaling. It sounds very much like Nitin has a PRI - the 24th channel is seeing lots of activity which is a pretty good sign of a PRI, but not always. It could be a regular incoming call on the 24th channel of a standard digital trunk, sometimes called a "supertrunk" by some carriers. Nitin, can you confirm with your telecom carrier that you do indeed have a PRI? You need to ask them if it is a PRI circuit or a standard 24-channel digital trunk. It looks like the framing and coding are correct: B8ZS and ESF, which are typical for both PRI's and digital trunks. Finally, if it is a PRI then you'll need to know what switch type they use: National, 4ess, 5ess, DMS100, etc. Some carriers call this the "protocol variant." Here's a sample of a zaptel.conf for my PRI here in California (Qwest): loadzone = us defaultzone = us span=1,1,0,esf,b8zs # My PRI line bchan=1-23 dchan=24 Here is a sample zapata.conf with PRI, where the switch type is 5ess: [channels] language=en context=from-pstn signalling=pri_cpe switchtype=5ess rxwink=300 ; Atlas seems to use long (250ms) winks callerid=asreceived usecallerid=yes hidecallerid=no callwaiting=yes usecallingpres=yes callwaitingcallerid=yes threewaycalling=yes transfer=yes cancallforward=yes callreturn=yes echocancel=yes echocancelwhenbridged=yes echotraining=400 rxgain=0.0 txgain=0.0 group=0 callgroup=1 pickupgroup=1 immediate=no channel => 1-23 Save your existing zaptel and zapata conf files and try playing with these settings. You might just figure it out without calling the telco, although if you spend more than 15 minutes tinkering you're probably in need of telco's assistance. -MC
