If connected behind the adapter, you don't have to worry about VoIP, just
use anything you'd use to record a regular analog phone conversation.

I'm expect that there is but I haven't used it. I'm no help there.

O.k., here goes...cancel the service if you can. Get a service which
doesn't lock you into their limited offerings. Then when you want to
do something interesting like this you won't have to work so darned
hard against your provider.

(I use Asterisk at home and I'm looking forward to adding lots of
recording features. I want records of business calls so that when
I'm told "Oh, no sir. We would never say that." I can play back the
earlier call.)

The latest version of ethereal can sniff the rtp packets and convert the
streams into a .au audio file. The only caveat is that the sniffer needs to
be on the same "wire" as the rtp packets. With high end switches this isn't
a problem because you can just span the ports. I don't think you can do this
with a residential router. You would have to use an old fashioned hub which
would drop you down to 10mbs/half duplex...not great for big file transfers
if you have more than 1 pc on your home lan.
