[Freeswitch-users] Delayed start of tone_detect

Tue Mar 22 22:53:30 MSK 2011

Ok, but this is not the solution for my initial problem: to delay the
tone_detect of 500mS after answer.
But I don't see any other way to do that (except modifying the
"switch_ivr_tone_detect_session" to ignore the first n samples).
