Can someone help me use Asterisk to provide SIP trunking to another PBX? I'd like to insert an Asterisk platform between a network PRI and an existing PBX. Incoming calls would (based on DNIS in a SQL table) go to PBX "A" on a PRI channel or PBX "B" as SIP. Outgoing calls from either PBX would select an available network PRI channel. --Don Don Kelly CT Magic 612 843-6060 888 Don Kell(y) 612 843-6061 fax
