Recording using SIP

For certain extensions I want to duplicate the audio streams and send them (mixed) to another SIP extension (SIP recording device).

I’ve found the monitor and recording options but they seem to support file output only, would it be possible to setup a 3 way conference for specific extentions/users by default so the recorder is dialed into the call automatically.

Then the SIP recorder can be part of calls and do realtime call analitics.
