I've gone through my ser.cfg and actually REMOVED every single sl_send_reply in an attempt to figure out where I've got these stray ACK messages being sent a reply, but even with NO sl_send_reply commands in there, I get that cursed message in the logs -- usually when dealing with reinvites (which I appear to also be having some issues with atm).
Is there something ELSE... some module or some such that might be causing this error other than a straight sl_send_reply command?
