I bought the Cisco SPA3102, which can do this, but it needs something like Asterisk to act as the proxie. I'm planning to rebuilt my Linux based firewall soon, so when I do that, I'll look at installing Asterisk on it.

To add to this, is it possible to use a Siemens OptiPoint 500? It has a USB interface, so could I take a USB like adapter and use it as a regular phone?

VoIP phone on POTS line... backward, but is it possible?

Hello all

Please forgive my ignorance. I'm not even sure what I want to do is easily possible.

I have a regular BT POTS phone line. I have a nifty VoIP phone. I was wondering if it's possible to use this phone on my regular BT line.

From what I presume (and I may be totally off the mark here), an ATA will do exactly this, but the other way round.

Ideally, I want to connect some kind of adapter to my BT line with the RJ11 cable, and my VoIP phone to the adapter and hey presto, I can use this awesome looking phone with my regular phone line.

I'm sure it's not that simple, but I thought I'd ask anyway.

Any help appreciated.
