[Freeswitch-dev] sleep()

[Anthony Minessale]

Just putting the channel in a loop calling switch_read_frame() is an ample
way to keep the channel idle.
That really is all switch_sleep does but you can't call it from some other
thread.  The session thread must call it.
You should never call any functions on a session from some other thread
unless it is not related to media and even then should be used sparingly.
