Answer 1: yes, this is possible.
Answer 2: Get yourself a Junghanns QuadBRI (8 audio
channels) or a OctoBRI (16 audio channels).
I haven't played with the OctoBRI, but the QuadBRI rox.
If your telco allows you to set your outgoing callerid to
one of the assigned MSN's your all set.
Stability and sound quality are very good on the QuadBRI in
the setup I put it in for production.

Just my experience.
