I have a customer with a 7200 using a ITP-5121D phone. They currently have this phone in their office, connected to the same LAN as the 7200. If I set the phone to use the private IP of the 7200, everything works fine.
If I connect the 7200 to a Cisco RVS4000 router, which has a DMZ set up passing all traffic to the 7200 (router has a static public IP) and the router's firewall turned off, and then change the phone to use the public IP, I can connect to the 7200, the phone correctly identifies the user and extension number, but I can't hear anything in or out.
Any ideas?
