asterisk users - Dec 2012 - call recording via 3rd INVITE/SIP leg

I have a call recording (audio) requirement that isn't addressed by
local Monitor/Record features.

All signalling and media currently pass through the Asterisk servers,
so that won't be an issue.

Instead of locally recording audio, for certain calls I need to add
what is effectively a 3rd leg to the in progress 2-leg call.

This 3rd leg is a SIP dial to a URI and/or PSTN number.

I'm thinking I have to do this with a conference bridge config and add
a 3rd muted leg to the conference?

Suggestions?

If you don't want to incur the overhead of a full blown conference 
bridge you can use ChanSpy to spy on a channel. It will provide a mixed 
stream of the incoming and outgoing part of the channel. So essentially 
use Originate to call your 3rd leg and then have it execute ChanSpy with 
the correct criteria to get to the right leg.
