Hi. I built a small lab to test asterisk-ss7. Two boxes with quad-t1 cards, .. with two T1s on each box connected using a crossover T1 cable. BChan 1-23, SS7 Signaling=24 BChan 25-47, SS7 Signaling=48 If I specify sigchan=24, then sigchan=48 I'm not able to make calls if I unplug the T1 carrying sigchan=24 If I specify sigchan=48, then sigchan=24, I'm not able to make calls if I unplug the T1 carrying sigchan=48. When I unplug the first T1, I get.. [May 27 16:04:25] ERROR[23430]: chan_dahdi.c:11545 ss7_linkset: Alarm on link! [May 27 16:04:25] WARNING[23430]: chan_dahdi.c:11596 ss7_linkset: MTP2 link down (SLC 0) or, if I unplug the second T1, it says (SLC 1) What I would like to do, Is have two or more signaling channels over two or more T1s. I *should* be able to unplug one of the two signaling channels, and still have calls flow between boxes, but that doesn't seem to be happening. Any suggetions would be appreciated. FYI; I've tried. sigchan = 24 sigchan = 48 cicbeginswith = 1 channel = 1-23 cicbeginswith = 25 channel = 25-47 AND sigchan = 24 cicbeginswith = 1 channel = 1-23 sigchan = 48 cicbeginswith = 25 channel = 25-47 AND cicbeginswith = 1 channel = 1-23 sigchan = 24 cicbeginswith = 25 channel = 25-47 sigchan = 48 Lab is as follows.
