This is the weird thing, I tried to connect to my ISP service (PlusNet) who don't actually seem to understand the technology and were not very helpful with settings. Connected to both services using X-Lite, a softphone, but the RT31P2 won't connect to either. And there is a limit to how many I want to sign up to!

Linksys are currently suggesting I should use the gateway function through an ADSL adaptor straight off the RT31P2; but that is a little impractical as the phone line is actually in a different room to where I want the phone, I may yet try it though just to eliminate the idea. But I need to get an adaptor, which is annoying as I've allready got one, albeit within another router (The AGO41).

Is what I don't understand is that the softphone can connect without any port forwarding on the gateway, on an assigned IP address, where as the RT31P2 adaptor seems to need a fixed IP and ports forwarded. Any ideas?
