I have a "Cologne Chip Designs GmbH ISDN network controller" in my
asterisk box, and an ISDN line connected up to it. I downloaded the
bri-stuff 0.1.0-RC4a package from junghanns.net and used that to compile
asterisk using these instructions:
http://www.voip-info.org/tiki-index.php?page=Asterisk%20zaphfc%20install
When I try to call my asterisk box, my sip phone rings twice and then
the line is disconnected:
-- Going to extension s|1 because of immediate=yes
-- Accepting call from '21******' to 's' on channel 0/1, span 1
-- Executing Dial("Zap/1-1", "SIP/jamesdoherty") in new
stack
-- Called jamesdoherty
-- SIP/jamesdoherty-74a8 is ringing
Ri = 26098 TEI msg = 3 TEI = 7f
Ri = 25324 TEI msg = 3 TEI = 7f
== Primary D-Channel on span 1 down
Sep 30 03:48:35 WARNING[12300]: chan_zap.c:1942 pri_find_dchan: No
D-channels available! Using Primary on channel anyway 3!
== Spawn extension (default, s, 1) exited non-zero on 'Zap/1-1'
-- Hungup 'Zap/1-1'
"Ri = 25324 TEI msg = 3 TEI = 7f" <- these are rather disturbing. I
get
them regularly on the asterisk console.
When I try to call out from the asterisk box I get the following:
-- Executing Dial("SIP/jamesdoherty-3c5f",
"Zap/g1/0800225598") in new
stackSep 30 03:49:20 NOTICE[21521]: app_dial.c:727 dial_exec: Unable to
create channel of type 'Zap'
== Everyone is busy/congested at this time
-- Executing Congestion("SIP/jamesdoherty-3c5f", "") in new
stack
== Spawn extension (default, 0800225598, 2) exited non-zero on
'SIP/jamesdoherty-3c5f'
In my /etc/asterisk/extensions.conf I have TRUNK set to "Zap/g1"
(without the quotes) and an extension like the following:
exten => _0800.,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}})
exten => _0800.,2,Congestion
My /etc/zaptel.conf looks like this:
loadzone=nz
defaultzone=nz
span=1,1,3,ccs,ami
bchan=1-2
dchan=3
and my /etc/asterisk/zapata.conf looks like this:
[channels]
language=en
switchtype = euroisdn
signalling = bri_cpe_ptmp
pridialplan=local
echocancel=yes
immediate=yes
group = 1
context=default
channel => 1-2
Our provider tells us that the ISDN BRI units are in ptmp mode. The
zaptel and zaphfc modules *are* loaded and asterisk reports that I have
two channels:
zap show channels
Chan Extension Context Language MusicOnHold
pseudo default en
1 default en
2 default en
The card has its own IRQ:
12: 40452133 0 XT-PIC zaphfc
Any help would be appreciated to try and get this working :)
Thanks
