On v14-SP2, we have 2x Patton 4114 PSTN Gateways setup with 7 lines coming in. Toll Free 1 forwards to Line 1 (local). Line 1 through Line 6 are a hunt group at provider level. Toll Free 2 forwards to Line 7 (local). Line 7 is it's own number. The client would like to have all lines route to the same queue - no problem. The client would also like something to differentiate calls made to Toll Free 1 and Toll Free 2. My thought was in inbound caller ID mask based on the number called in the TO header. I've looked through 3cx blog posts, YouTube videos and these forums. I've tried many different things, but have yet to achieve the desired results. Any ideas, or is this even possible?
