If I understood correctly what you described, the calls to 3 different DIDs which will be directed to 3 Inbound Routes, need to be routed to different Outbound Routes.
If the above is correct, let me start by saying that if the Caller-ID shows up properly on the Call Monitor, then it is feasible to use a single DID to direct all the inbound calls.
Setup 3 Inbound routes one per DID, or 3 Inbound Routes for the same trunk (DID) using the Inbound Caller-ID to differentiate between them. Place the Caller-ID number in the "Caller ID Number" of the Inbound Route and direct it to a CallThru PIN.
Create 3 Outbound Routes and restrict who uses them by placing in their Extension field the Caller-ID as it is shown on the Call Monitor.
That should achieve what you are looking for, hopefully.
