You could look at the txjitter and rxjitter values (and other values) stored in the CHANNEL() function, and those values you're looking for were previously known as RTPAUDIOQOS. Or is this not sufficient? I opened a request ticket to allow viewing of arbitrary CHANNEL() data on any active channel, but to my knowledge it has not been implemented. The RTP source of media has however been impelemented in the CHANNEL() structure. It may be possible to use chan_local to ascertain media data on the "other" leg of a call, but I have not experimented with that. http://bugs.digium.com/view.php?id=9620 JT _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
