I checked the wiring and have dialtone at the CID unit. I'll have to check the ring delay timer as you suggested Derrick. If the ring delay timer doesn't fix it, what do I do next?

If I move the line to a different port on the CID unit, do I also have to move the line to a different port on the phone system? IE, if I move the line to port 5 in the CID unit do I also have to move the line to port 5 of the phone system?
