[Freeswitch-users] Detecting the origin of voice activity using VAD

[Henry Huang]

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 connect the
other leg of the call. The point is to hold the first leg till a real person
picks up.

If it can't be done by VAD, how should I approach this function that I want
to achieve.

Thanks
