Twice in the past few weeks we have had calls where the audio suddenly went "one way."
The first time it happened, it was about 30 minutes into the call. It happened again today, about 5 minutes into the call. The sipXtrace looks normal: Time: 2009-12-18T15:51:44.184000Z sipXbridge -> sipxecs Ringing Time: 2009-12-18T15:52:02.664000Z Remote -> sipXbridge OK Time: 2009-12-18T15:52:02.681000Z sipXbridge -> sipxecs OK Time: 2009-12-18T15:52:02.712000Z sipXecs -> sipXbridge ACK Time: 2009-12-18T15:52:02.717000Z sipXbridge -> Remote ACK ----- Audio went one way in here somewhere ---- Time: 2009-12-18T15:57:57.108000Z sipXecs -> sipXbridge BYE Time: 2009-12-18T15:57:57.113000Z sipXbridge -> sipXecs Trying Time: 2009-12-18T15:57:57.118000Z sipXbridge -> Remote BYE Time: 2009-12-18T15:57:57.137000Z Remote -> sipXbridge OK Time: 2009-12-18T15:57:57.142000Z sipXbridge -> sipXecs OK Given the very intermittent nature of the problem and the fact that nothing out of the ordinary shows up on the sipXtrace, does anyone have suggestions on how to try to reproduce the problem reliably and/or troubleshoot it? My only thought at the moment is to run tshark all day, every day, possibly stopping and restarting it every hour or so, if no problem occurs to keep the output from getting out of control.
