You've sent a block for a single CIC, you've received an CGA for 32 CICs. If that's 'fine' by your standards, then it's fine allright.

If you have a single span in the linkset l1, or you have less then 42 CICs assigned to that linkset, then everything is allright here. Don't be fooled bu the do_group_circuit_block_unblock message - the real mask sent is not what it says it is. Connect your protocol analyzer to that link, monitor it for a while. See what really gets sent there. I think it's a known bug in chan_ss7 it sends the CGB/CGUs wrong (the range is always 32 there). That's why you see the CGA with range=32 in the first example, despite trying to send ithe CGB with range=1. The problem should have come out during the interconnect testing procedure though... -- Jakub Klausa | j.klausa at ss7.pl | http://www.ss7.pl/ | http://www.ngpbx.pl/ Dane rejestrowe -> http://kontakt.ss7.pl -------------- next part -------------- A non-text attachment was scrubbed...
