well, they dont seem to be giving, (they think this problem has something to do with the asterisk+libss7 & they dont know abt these two), but in my guess there is something to do with the channels i.e. CICs, i m yet trying to get CICs somehow from them, from IAM thorough a protocol analyzer may be. besides this all, even i m not yet able to up the link with chan_ss7 as well, it works upto recieving IAM but possibly is not able to send back the ACM or ANM that is why no calls are received & the caller finds the line as busy (congestion). so what can you or anyone suggest me -------------- next part -------------- An HTML attachment was scrubbed...
