<p class="MsoNormal">hello Claudio Aznar!<br>
<br>
I guess you may feel luckier reading this post, as I was the one victim of the
same problem that you are currently in (problem: bringing the asterisk server
up on SS7 link with SIEMENS EWSD for successful calls, be it chan_ss7 or libss7).
I tried both & had the same results as you have for each one, I explained
& posted the same as you did rather more than that including exchange of
posts with Mathew Fredrickson. Then, in an effort of<span style=""> </span>leaving no stone unturned, the solution came
across & was lying in changing the CIC on EWSD side from 1 to 0 while
keeping firstcic=1 on asterisk (chan_ss7-0.8.4 or 0.9). doing this made every
thing working fine i.e. all channels became idle & started receiving calls.
Because the CIC mapping on the EWSD side starts from CIC = 0 & remains the
same for the whole trunk group i.e. E1, and for the next trunkGroup/E1 there is
another CIC, they represent it like this:<br><br>CIC=0-1<br>CIC=1-2<br>CIC=2-3<br>… <br></p>
<p class="MsoNormal" style="">Where
in CIC=0-1, the '0' specifies the CIC and the '1' is the trunkGroup/E1 number
and similarly in CIC=1-2, the '1' is CIC & '2' is E1 number and so on. So based
on my experience, I can guess with a high probability that your telco side has
set CIC=1-1 on their EWSD as they generally do it. If on EWSD you find it so, then
ask the EWSD ppl to change their CIC to '0' for the trunkGroup/E1 that is for your
asterisk server connectivity and keep your firstcic=1 & channels =>
1-15,17-31 in the link settings in ss7.conf <br></p>
<p class="MsoNormal" style="">I hope
it'll work for you too <br></p>
