[Freeswitch-users] Delayed start of tone_detect

Tue Mar 22 20:59:37 MSK 2011

I cannot slow down the call rate, this is a real traffic and is not
generate but the session rate it's not a real problem because my session
rate is never more then 100cps with a medium value of 50cps so, when I
activate this sleep, Freeswitch calculate a wrong CPS value. It seems that
during sleep, FS freezes, as the sleep is performed synchronously.

Another effect is:

2011-03-22 09:17:57.551069 [ERR] mod_freetdm.c:2177 Session for channel
29:15 not found [UUID: N/A]

2011-03-22 09:18:07.797798 [ERR] mod_freetdm.c:2177 Session for channel

and many calls are dropped (I never seen these errors before).
Removing the sleep from dialplan, all revert to normal.
