[Help] "Circuit-busy" problem

Asterisk Asterisk Support
1

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

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

signalling = bri_cpe_ptmp
context=isdn_pbx

group = 3

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.

3

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

4

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

Regards,
Mircea.

5

Yes, I tried that, no luck!

I got similar issue and started working once I enabled the correct outbound callerid in freepbx.
