I?m not a chan_ss7 user, but I remember there was a bounty a couple of years ago. As far as I know, there wasn?t enough funds to sort it out. libss7, as well as chan_ss7, can receive CCR and make a loop in the channel at the incoming perspective, which is really trivial on the code. But at the other side, cannot send a CCR, send the tone and turn on the code receiver to listen if the tone is there. Maybe it?s time to propose a bounty on this. ?

My DAHDI is using channel numbers 1-31, 32-62, 63-93, 94-124 for first 4 spans. You are configuring your span4 with channels up to 127, but 125-127 are probably on span5. You have Red alarm on these channels, probably you don't have anything connected in span5 (no link). Try to correct channel numbers in /etc/dahdi/system.conf and also chan_dahdi.conf and use intervals which are listed above (but exclude channel used for signalling in span1). >> >> If your peer really use CIC numbering as he sent you, probably you will do something like this in /etc/asterisk/chan_dahdi.conf >> >> channel=17-31 >> cicbeginswith=33 >> channel=32-62 <<< changed >> cicbeginswith=65 >> channel=63-93 <<< changed >> cicbeginswith=97 >> channel=94-124 <<< changed >> >> >> M.R. >> >> > > > -- > _____________________________________________________________________ > -- Bandwidth and Colocation Provided by http://www.api-digital.com -- > > asterisk-ss7 mailing list > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-ss7
