[Freeswitch-users] Call Waiting + FIFO

Tue Jul 29 02:53:13 MSD 2014

Michael, after talking with bkw in the chat, it seems FIFO does not support
call waiting.  However he mentioned setting the LAG to a lower value, with
a LAG set to 1, and a member timeout set to 60, when i call in, and answer
the first call, then call in with a 2nd call waiting in the queue, if i
hangup the first call, it waits the entire 60 seconds of the member timeout
before ringing me again.
