Wed Dec 6 00:15:29 MST 2006

ok i re-checked & installed every thing (zaptel-trunk, libss7-trunk &
asterisk-trunk), there is no
problem except for one i.e.

Asterisk Ready.

====================

moreover when i tried to restart the zap channels, the following happened:

====================
*CLI> zap restart
 Destroying channels and reloading zaptel configuration.
  == Parsing '/etc/asterisk/zapata.conf': Found
[Nov 25 02:39:52] ERROR[30884]: chan_zap.c:11347 linkset_addsigchan: Unable
to open SS7 sigchan 16 (Device or resource busy)
[Nov 25 02:39:52] WARNING[30884]: chan_zap.c:10661 zap_restart: Reload
channels from zap config failed!
Command 'zap restart' failed.
*CLI>
====================

it says that it is unable to open sigchan 16, but here i must tell u that
there is another server beside ours (that does'nt use asterisk), it runs all
fine on that system when we plug the same link into that system with the
signallin on 16th channel, confirming that there is no problem with the ss7
link

my new zapata.conf is :

=====zapata.conf======
[channels]
context=ss7
switchtype=5ess
usecallerid=yes
hidecallerid=no
echocancel=yes
echocancelwhenbridged=yes
musiconhold=default

signalling = ss7
ss7type = itu
linkset = 1
pointcode = 4872
adjpointcode = 4872
defaultdpc = 4872
networkindicator=national

;sigchan => 16
;channel=>1-15,17-31

sigchan => 16
cicbeginswith=1
channel=>1-15
cicbeginswith=17
channel=>17-31
===================

no call comes in & nothing occurs on the CLI ever (except for the
error messioned above), plz help
