[Freeswitch-users] Problems with RTP delay at around 300 concurrent calls

Fri Jun 27 23:09:21 MSD 2014

Hi Guillermo,

Short answer: I'm not sure.

Long answer: I think this timer is to detect if there is no rtp. Sometimes
you would want to know if there is no RTP and then hang up the call to
avoid possible ghost calls in your system. For instance if there is a call
between two sip phones and they both get disconnected without sending a
bye, the call could stay active in freeswitch even though both sides are
dead.

Another alternative to that, if you think your environment is prone to that
sort of scenario, is to user session timers to ping the devices in a call.

>From performance point of view, it makes a big difference.

Regards,
Ali Pey
