Running Unity 3.1 (6) and Call Manager 3.3 (3). Transcoding sessions are hanging causing Unity to be flooded with ICMP traffic. This seems to be causing Unity to drop calls and messages that are being recorded to be very choppy. The areas that are causing the transcoding session to hang are remote sites running G.729. Any ideas as to why the transcoding sessions would hang and is this result expected? Thanks again for your help.
