The 'release' procedure is this: A REL is sent to the other side, and if a RLC is not received within T1 seconds the REL is retransmitted (and T1 restarted). This cycle continues until a RLC is received. If a RLC is still not received within T5 seconds, the timeout-interval is changed to T5. In chan_ss7, T1 is 30 seconds and T5 is 600 seconds. So chan_ss7 will end up, retransmitting the REL every 600 seconds - forever (if it doesn't receive a RLC) > I've strange issues with one of my telco's.

Well this is a little strange, since there is no timer in chan_ss7 which is setup for 3600 seconds (1 hour!). > Any help is highly appreciated! > ,"SS7/15","IAX2/axsoftsw1-16389","Hangup","","2006-04-21 23:04:54","2006-04-21 23:05:00","2006-04-22 00:04:59",3605,3599,"ANSWERED","DOCUMENTATION" > ,"SS7/19","IAX2/axsoftsw1-16392","Hangup","","2006-04-21 23:05:23","2006-04-21 23:05:29","2006-04-22 00:05:28",3605,3599,"ANSWERED","DOCUMENTATION" > ,"SS7/11","IAX2/axsoftsw1-16393","Hangup","","2006-04-21 23:46:00","2006-04-21 23:46:07","2006-04-22 00:46:07",3607,3600,"ANSWERED","DOCUMENTATION" > _______________________________________________ > --Bandwidth and Colocation provided by Easynews.com -- Can you try to dump the ss7 trafic and post it on this list ?
