asterisk users - Mar 2005 - Detect sound and continue, like BackgroundDetect() for voice

I'm looking for an application that can monitor a channel for voice
input and then proceed on.  The closest thing I've found is
BackgroundDetect, which expects DTMF.

Here's what I'm doing:
-Call file generated which calls someone and connects them to an
extension.
-Extension plays stuff, etc. etc. etc (not important)

With digital or VoIP termination, this works fine, because * knows when
the line is answered.  On analog POTS, it has no idea when the call is
actually answered, only when its dialed, so the playback starts right
after the line is dialed, not after the called party picks up.

The Dialogic IVR SDK monitors call termination status this way, so I'm
looking for something similar in *.  Anyone have any ideas on this one?
Or am I going about this the hard way and missing an obvious
alternative?

Thanks,
Daryl

Yes, you missed an obvious option - search the mailing list. This has 
come up an number of times.

Yes, I'm replying to my own post.

Roger Gulbranson suggested this:
http://www.voip-info.org/tiki-index.php?page=NVBackgroundDetect

As he's using it for FAX detect, and it has a "talk" option as
well.

If anyone is interested, I'll report back with my results.

Thanks Roger!

I searched both the Wiki, and the list.  But I obviously didn't come up
with the right search terms, or overlooked relevant results, which is
why I asked.

How about this: the next time I have a question to ask, I'll call you
first to ask for what search terms to use before posting.

What's your mobile number?

Thanks,
Daryl
