[Freeswitch-users] Choppy sound with PCMU

[eaf]

Oh, looks like the timers are also used for streaming local data in
read_stream_thread(). Due to this there is always one timer active with 20ms
interval.

But wait a sec, why is freeswitch periodically trying to stream
/opt/freeswitch/sounds/music/8000/ponce-preludio-in-e-major.wav somewhere?
Every minute or so? Did I misconfigure it?
