I have a medical office that is moving out of their existing suite and into a new office across town. The management company would like to make their existing PBX (Non IP) tie into the phone system at the new office.

They are having a P2P T1 Installed.

I'm thinking :

(Existing PBX)-->(Adtran 850)-->(Adtran Router)<---P2P-->(Adtran Router)-->(Adtran 850)-->CO line ports on ESI Switch.


Any other product suggestions?
