7921 Wireless IP Phone UDP/TCP Port Usage

I'm planning a 7921 Wireless Deployment and wondered which ports are absolutely necessary to connect to CCM. I've seen several lists, but there seemed to be a large number of ports open, and wanted to check with someone who had actually depoyed before going that far.

See the following doc in regards to TCP/DUP port usage.

See the 7921G Deployment Guide for further info.

Yeah, I've read that ("Seen several lists"), but wondered if anyone had deployed and knew the bare minimum that one could get away with, considering the 7921 may not have the same needs. Thanks for the reply, regardless!
