Device to connect PRI to old PBX & New?

Posted:Fri 12 of Jul, 2013 (22:57 UTC)
We have a full PRI T1 coming in from AT&T. Currently, it goes directly to our Mitel 3300 IP PBX. I'd like to begin implementing a new SIP (Asterisk/Trixbox) PBX. What product can I use to route only specific DID numbers to the new PBX, while keeping all other DID's routed to our current Mitel?
So, AT&T PRI T1 to (Digium G200?) to both current Mitel (over T1/PRI cable) and to new Asterisk PBX (over ethernet). Inbound calls routed to one or the other PBX, based on its DID number.
