[Help] "Circuit-busy" problem

Using Asterisk 1.2.7.1 (Asterisk@HOME 2.8), bristuff 0.3.0-PRE-1o and a Junghanns quadBRI ISDN card, I am trying to pass-through a call from Asterisk to PBX (and eventually to phone).

|ISDN NT| — |Asterisk@HOME| — |PBX| — |Phone|

When I dial, I keep getting the message:

Zap/7-1 is circuit-busy

Asterisk configuration is as follows:

/etc/zaptel.conf

defaultzone=gr

span=1,1,3,ccs,ami
bchan=1,2
dchan=3

span=3,0,3,ccs,ami
bchan=7,8
dchan=9

/etc/asterisk/zapata.conf

[channels]
switchtype = euroisdn

pridialplan = local

context=isdn_in

group = 1
; S/T port 1
channel => 1-2

signalling = bri_cpe_ptmp
context=isdn_pbx

group = 3
; S/T port 3
channel => 7-8

/etc/asterisk/extensions.conf

Any ideas what’s wrong?

Thanks for your time,

Hy,

Which PBX are you connecting with? I assume the connection with the PBX is through T0?!

Regards.

The PBX is an Auerswald COMpact 4410 USB. It is directly connected to Asterisk (quadBRI ISDN card).

Have you tried to use immediate=no in /etc/asterisk/zapata.conf?

Regards,
Mircea.

Yes, I tried that, no luck!
