We have a few Omega IX IP phones. One of them was moved from the home of the user to an office inside the same building as the ADIX box.
The extension is staying the same however now we get one way communication. They had the IWATSU guy come and he called them and told me to open UDP 5000-5998, TCP 50000, and RPT 6004-6998.
I'm not even sure what type of port RPT is but I opened those ports on TCP and UDP for the hell of it . We are just using a D-Link router so I forwarded all those ports to that phone's IP address.
The phone is picking an IP address from a Windows Server 2003 DHCP box. It has NAT enabled.
I can't figure out what else to do...besides blow up the phones. LoL
