Without using a DNS service is there a way to access the configuration GUI via the web?

It would seem there's a way to do it. Seems like on the user end it would require a manipulation of some sort to make the client side think software is installed on the end user side.

I developed a page on my server to access the Talkswitch. All I have to do is figure out how to make it work. See a screen shot of the page.

Has someone figured out how to do this with a single Talkswitch via the web without having to have configuration software installed on every PC?

I am not speaking of a Talkswitch utilizing VoIP.
