[Freeswitch-users] FreeSWITCH Voicemail - silence detection

[Michael Collins]

Yes, you can control this. The threshold value is described here:
http://wiki.freeswitch.org/wiki/Mod_voicemail#record-silence-threshold

The silence hits is described here:
http://wiki.freeswitch.org/wiki/Mod_voicemail#record-silence-hits

Both of those link to the docs for the wait_for_silence dialplan tool, which
discusses these values in more detail:
http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_wait_for_silence#Description

In a nutshell, if you lower the threshold value then that means the silence
needs to be "quieter" to be considered "silence." So, for a soft-spoken
voice you would want to lower the threshold. I would experiment with that.
Note that if you set the threshold too low then no silence will ever be
detected. As for the "hits" value, that just tweaks how much silence FS
needs to detect before it assumes there is silence on the line. The higher
the number of hits, the longer the silent period needs to be for FS to
assume it is "silence."
