[Asterisk-Users] channel offset between Asterisk and PBX

[Roman Sidler]

Hi
We interfaced our ASCOTEL PBX  to Asterisk. by EuroISDN PRI , DSS1
It works fine on channels 1- 15, but on 17-31 the miststood each other.
Asterisk speaks in Timeslots, the PBX in B-channels

The signalling is ok, but the bridging is shifted. The first incoming 
connection is bridged to "nirwana" also no indication is hearable,
calling a second internal subcribes bridges them to the first.

The PBX sends a SETUP message with channel identification 30 and Asterisk 
bridges them to Zap-30, instead of Zap-31. 

The configuration
- Digium TE410p card, set for E1

________in zaptel.conf________
span=1,1,1,ccs,hdb3,crc4

bchan=1-15
dchan=16
bchan=17-31
________in zapata.conf________
signalling => pri_cpe
switchtype => euroisdn
context => pri1-in
pridialplan => unknown 
channel => 1-15
channel => 17-31


What's wrong? 
Thanks in advance

Roman
