Hi,<br><br>I doubt ss7 starts transmitting audio because I can see asterisk does not actually include optional backward call inband information parameter, inband information parameter should be set to 1 for audio path to open before ANM. I believe some switches could be configured to force this behavior. You might want to record on a dahdi channel to make sure if audio is being transmitted after ACM<br>
