[Freeswitch-users] Asynchronous PTIME

The switch is receiving audio frames larger than it should for the
negotiated codec, which causes it to analyze the timing of received frames
and correct the issue. To stop the switch from trying to fix the timing you
should be able to uncomment the rtp-autofix-timing line in your related
sofia profile, but I cant speak to whether that will fix your audio.

There is a logfile.conf.xml to alter any of the settings of how the switch
logs to file. For debugging SIP to log file you should do it outside of the
switch console, for instance with ngrep.
