[Asterisk-Users] Problem with integrating ISDN PBX using NT mode

[Alyed Tzompa]

 == Primary D-Channel on span 4 down for TEI 65
 == Primary D-Channel on span 4 down for TEI 64
 == Primary D-Channel on span 4 down for TEI 66 

This looks like a signaling problem, check out your configuration in zaptel.conf and the log messages you get at /var/log/messages
 You can also post them here if you continue experiencing problems.

Hi,
I'm just in the process of replacing a crappy Siemens PBX with a new and
shiny Asterisk system. To connect Legacy equipment I hooked up a small
ISDN PBX (DeTeWe OpenCom 36) to one port on a Junghanns.net quadBRI
card. That port is configured for NT Point to Multipoint
(Mehrgeraeteanschluss) mode. Now I can place calls from the ISDN PBX to
the other Asterisk extensions but the other way around does not work.
Whenever I call from the Asterisk server to one of the extensions
connected through the ISDN PBX that extension rings for a split second
and then the call is dropped. Here is what I get on the console:

 -- Executing Macro("SCCP/13-0000002f", "standard|Zap/g2/40") in new
 stack
 -- Executing Dial("SCCP/13-0000002f", "Zap/g2/40|20") in new stack
 -- Requested transfer capability: 0x00 - SPEECH
 -- Called g2/40
 == Primary D-Channel on span 4 up for TEI 64
 == Primary D-Channel on span 4 up for TEI 66
 -- Zap/10-1 is proceeding passing it to SCCP/13-0000002f
 -- Zap/10-1 is ringing
 -- Channel 0/1, span 4 got hangup request
 -- Hungup 'Zap/10-1'
 == No one is available to answer at this time (1:0/0/0)
 -- Executing Goto("SCCP/13-0000002f", "s-NOANSWER|1") in new stack
 -- Goto (macro-standard,s-NOANSWER,1)
 -- Executing VoiceMail("SCCP/13-0000002f", "u40") in new stack
 -- Executing Goto("SCCP/13-0000002f", "default|s|1") in new stack
 -- Goto (default,s,1)
 == Channel 'SCCP/13-0000002f' jumping out of macro 'standard'
 == Primary D-Channel on span 4 down for TEI 65
 == Primary D-Channel on span 4 down for TEI 64
 == Primary D-Channel on span 4 down for TEI 66

I think I properly configured the ISDN PBX (theres not much to configure
there). Can someone help me here? What's causing the hangup request? How
could I find out?
Below is the relevant configuration.

Thanks in advance,
Frederik Fix
