Hi, 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 Regards, Anil PS : Its will be better if you start a new thread for this.
