In a sense, you might say I did futz with mod_vmd ... to create mod_vad.
There appeared to be just no (easy) way to modify the internal VAD code in
the FreeSWITCH core (see switch_rtp.c) to identify the origins of voice
activity. And rather than build into mod_vmd, which is a special purpose
tool,
Kewl you can contribute via http://jira.freeswitch.org ;)

I think that's right. It just does the opposite - instead of looking
for differing power levels it looks for the same power level. In other
words it tries to detect distinctly

Hi,
mod_vmd is a bit more sophisticated than that. It looks for the signal
being narrowband energy. However, mod_vmd isn't very reliable, as it
takes a rather high SNR for its narrowband detector to work. So high
that a lossy codec like G.711 can barely manage it.

Using voice activity detection (VAD) in FreeSWITCH, how might I then
distinguish which side of a call any given TALK or NOTALK event
Does the freeswitch VAD is able to distinguish ring tone from human voice?
The scenario is to originate a call to a IVR system(don't connect the other
leg here yet) and dial DTMF to get to the designated extension number , once
someone picks up and say hello ( detected by VAD) now release to
Well, I knew it would be some future fantasy for now..
If not human detection. I guess will try to use Dialplan Tools wait for
silence to wait till the ring tone is finished ,then connect the other leg.

ignore_early_media=true is not going to do the trick since once the IVR
picks up the call on leg A, the ring tone is stopped and the IVR is going to
play pre-recorded voice menu. And the freeswtich is going to send DTMF to
reach a certain extension number say 101. Then the ring tone is going to
