I can check sound in line and find out if it's voice or not? or was
your vox recording based on just level of signal?

I only know how to use the signal level. But voice squelch
is probably a bandpass filter (for voice frequencies) before
the signal level is measured...I wish I knew.

is there open source algorithm which I'd be able to use(c,c++ or java)?

I don't know. But I did a google and saw some info about it.
You might be able to find somebody who submitted some code
to CodeProject.com or CodeGuru.com maybe.

I can help explain how mine works if you send an email to me
at the same address except the domain is davee.com. I use
c++ for my algorithms.
