I'll try also with this changes in Freeswitch:
--- a/src/switch_ivr_async.c
+++ b/src/switch_ivr_async.c
@@ -2681,6 +2681,12 @@ SWITCH_DECLARE(switch_status_t)
switch_ivr_tone_detect_session(switch_core_sessi
}
}
+ if ((var = switch_channel_get_variable(channel, "tone_detect_delay")))
{
+ int tmp = atoi(var);
+ if (tmp > 0) {
+ cont->list[cont->index].sleep = tmp;
+ }
+ }
if (zstr(flags)) {
bflags = SMBF_READ_REPLACE;
using the "tone_detect_delay" channel variable to set the initial delay of
tone detect.
