Probably the phone is using a "wrong" DNS entry. Try changing the Proxy address to the IP address and see if the phone registers.
If so, work backwards from there. Change DNS setting to some other DNS. And, remember you have to set an IP DNS, you can't use a URL to look up a DNS. (Assuming you don't have a DNS available to start with.) Also some low end routers are a little flakey about getting a real DNS and serving as a DNS for downstream devices. It is more sure to specify YOUR DNS addresses on the phone.
