Henry, I can't speak to the router, or your ITSP provider. I can state that I have a site running on 4.4 with a single server, server provides DHCP and DNS, and works with SPA942 phones. I did not use the wiki recommendations. I simply provisioned them via the management templates and they work perfectly.
Trunks are provided via a PRI gateway - I've used Epygi and Patton gateways at this site with great results from both of them. I would suggest router or ITSP are your issue, as others have. VOIP.ms is a low cost ITSP provider that for a minimum investment you can use to test. We know they work, and for a few bucks you can save yourself some time in troubleshooting.

It is a small business router. Having said that it still may not mean it is a suitable router for SipX. I managed to obtain another router and do more testing tonight. The router is a Linksys/Cisco RV016. It has one-to-one NAT and I set it up to have a one-to-one NAT entry between my internal sipx server and the router's external interface. Using the RV016, the following test results were obtained (please note that I had to port forward 5080, and 30000 to 31000, otherwise external calls would come through with just one-to-one NAT setup and enabled): All the previous test results remained exactly the same. That is to say internal calls could be transferred to voice mail when no one answer the calls but external calls could not. I then setup forwarding directly to voice mail by calling the external voice mail DID number that I setup. That worked!! I am beginning to think that it may have to do with how the SPA942 operates or it was not setup properly via the sipxecs web interface. But I am not knowledgeable enough to examine and change the settings on the SPA942. If anyone can give me suggestions to troubleshoot this problem, I'd much appreciate it.

Just because it works as a home router for voip doesn't mean it will probably work for your office hosting a PBX, BIG FAT difference.
