I’ve had an idea about a system that combines POTS and VoIP lines. I thought it might be a plan to connect the Asterisk server and the POTS phones on a splitter so that if the Asterisk server was down, the POTS phones could still make and receive calls. But I’d like to send long distance over VoIP. I was wondering if I could do a scenario like this.
- User picks up POTS handset.
- User dials 1- or 011-
- Asterisk server goes “Holy cow! This must be a long distance call!”
- Asterisk disconnects the POTS line, switches the user’s phone to VoIP, and completes the call.
If anyone has any other ideas that would be similar, that would be appreciated as well.
