Everything that I've read indicates that a "no audio" problem with SS7 generally indicates misaligned CICs but according to the operator they are reported to be aligned ok. Alignment on link does not mean that - you start counting CICs from "1" and your partner does the same (one is one on both sides, some telco switches count 1st CIC as 0, or even 2). > CIC: 1 > ;Sangoma A102 port 1 [slot:4 bus:12 span:1] <wanpipe1> So - it should be 1st CIC > ;First E1 > sigchan=16 > cicbeginswith=1 > channel=1-15 Here you say, that first available channel has logical number one, and you try to make 1st call on CIC 1, so it looks good. Maybe simply - you should try to disable one E1 link? Simply comment out - the second E1 and see if it's not mis-cabling ? If the same "no audio" happen on the only one digital link (one E1) - it's in 99.999% - mis numbered CIC - have you access to any passive "recording" equipment ? Another Sangoma card with at least 2 ports could allow for listening if audio is being put on any timeslot (CIC, timeslot, Bchannel - call it as you wish).
