[Freeswitch-users] Noise Detection

[Michael Collins]

You might want to check out using a conference. The mod_conference module
can emit a number of different events, including start talking and stop
talking events. I would recommend that you add the channel to a conference
room and then monitor the conference::maintenance events as sound is
received on the channel.

If it works then you might even be able to have multiple conference members
for different areas of the house. That could possibly let you narrow down
where in the house the noise is occurring by observing which conference
member is 'talking.'
