FXS to FXO idea

I have an idea of a voip gateway box. I guess you would call it that. I don't think this device exist yet.

You could call from your cell phone or another local number to your voip line. It would pickup and give you a fake ring to enter an access code. After the correct access code, you would get get a simulated dial tone or beep. Then you would enter the long distance number you want to call. The voip line would then use three-way calling to call the number you just entered. When your done with the connected call you could punch a special tone sequency to disconnect all connections.

This would be a way to make a free long distance call from a cell maybe that you can make free local calls on. Also, when you fist call in and don't enter the special security access code to use the device after so many seconds. The device would trigger the other house phones to ring like normal. Maybe this could be done with a modem and software?

Asterisk will do that for you, investigate the AGI scripting language or just make a simple dialplan. Saw this today.. Complete Debian+Asterisk install (beta) on a CD

The cellular capable device you attach might be.

A regular cell phone Via some home brew adaptor USB, Bluetooth, etc Analog patch cables to sound card Via some commercial cell to traditional phone adaptor Note that one of these has a serial line controller option

A PCMIA cellular card More home brew to get the analog connection

A "Fixed Cellular Terminal" - i.e. a device intended for this.

The SPA-3000 should handle this on its own. I'm not good enough with its dialplans to know though.

The term used for this idea is apparently "port converter".

I guess it depends on what country you're in, but I haven't see a cell plan in a long time that does not include free long distance and local calls are per-minute (which you would still have to pay) so where is the savings?
