I am setting up a Partner ACS (R7) behind a Definity PBX. There will be 7 CO Lines from the LEC and 2 Extensions from the Definity PBX. These 2 extensions will be plugged into the Line Ports of the Partner. When a Partner user wants to call an extension on the PBX, they can select one of these lines and dial directly. No problem so far. What I need to know is how do I transfer a call that has come in on one of the 7 CO Lines to an extension on the PBX (Trunk to Trunk Transfer)?
