I have an IP Office system with 1608 phones. The phones work great with every ISP except Verizon FIOS (actionet router). I connect a phone at one persons home on Optimum and it works. I take the same phone to a Fios location and it will not work. I am statically assigning the IP. I have added the IP as a DMZ on the router. Any ideas?
