I believe Steve U. has repeatedly commented on the need to have a very stable pstn interface, no missed interrupts, no frame sleeps, etc, etc. To me that translates into resolving well-discussed issues with the tdm04b card, etc. So, not likely you running into line noise, but rather missed interrupts,etc. (I have had the same proble with the spandsp here.) _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
