Well, with mine, here's the setup.

I have a USB hub connected to a Linux box with two USR USB modems. These are plugged into a Grandstream VOIP adaptor, one line configured with the US number, and on the UK.

On the linux box I have two processes running that listen on each tty for an incoming call, it's actually using sexpots, the Synchronet External POTS systems or something like that.

This can be configured in two modes, the first is that it'll open a tcp/ip
connect to whatever host/port you want.

The second is that it can display a menu and you can pick what you want to connect to. This was added by DigitalMan at my request. This allows me to run aboth a regular terminal and a viewdata board using the same line.

Keyops is just a login to a Linux server which then does a telnet out.

Synchronet doesn't directly handle dialup connections so there is something in between and it seems to work quite well.

No idea, to be honest. :)

When most people are using cell phones or VOIP, not very, but for those stuck without any other option but copper, it's still one way to get information. It's also good for people in countries where their internet is censored and they want some way to exchange messages.

Thanks for the interest,
Nigel
