I currently have a FreePBX setup with SIP trunking based on Callcentric. I’m going to be switching ISPs soon, and they are giving me a free phone line with unlimited minutes, which I want to use.

b) What gateways are certified to work with Asterisk?
c) How can I set up the gateway?
Digium, Sangoma and Rhino all make cards that you can install in the server. You need what is called an FXO interface. There are also external adapters that you can use…
