I have also updated from 1.6.2.7 to 1.6.2.8 but it haven't changed anything for me :-( The only way I have found to make it work is to make my callweaver pbx to generate the ringtones. So it is transmitted to my ss7 gateway as an rtp flow which is sent to my provider over the ss7 channel, which is not very optimal... Do you (or anybody in the list) know a way to capture the signalling + voice on a given CIC ? I have tried ss7 dump command but it only captures the signalling. I have also tried the dahdi_pcap patch (https://issues.asterisk.org/view.php?id=16831 ) but I get a ton of garbage as I have no way to filter over my point code. Thank you ! Regards, - vma .
