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.

PING northamerica.sipphone.com (198.65.166.131) 56(84) bytes of data.

64 bytes from northamerica.sipphone.com (198.65.166.131): icmp_seq=2

Is this a bug, or could it be caused by a faulty configuration?
