Well, I finally got my phone working on my recently transferred VOIP service.  As I suspected, VOIP.COM requires that (if installed behind a home router) certain ports be opened to faciliatate the reception of incoming phone calls.  Below is the list of the ports & instructions necessary to get the VOIP.COM service working behind a commercial grade router:

  • your protocol has to be UDP Inbound and Outbound.
  • port 21
  • port 53
  • port 69
  • port 123
  • port ranges, 5060-5061
  • port ranges, 10000-20000

Now, why these directions are not on their web site is a whole other question ….
