There can be several approaches to the mechanics of this. Some more elegant than others IMHO. You could use chan_bluetooth to connect an old cell phone. You can get a "Dock-n-talk" to bridge from the celullar to fixed line world. I my case I bought a single port SIP-GSM gateway that takes a SIM card from my cellular provider. I then made the gateway a peer to my Asterisk. Voila...a GSM trunk. Add dialplan logic to route 411 and 911 calls to that trunk and away you go. Such gateways are available from 1 to 32 ports. Some are GSM - FXO while others are GSM - SIP/H.323. Some are even GSM - Skype. Just Google "GSM gateway" and follow the bread crumbs. I'm half way through an article on the project that will eventually fin its way to www.smallnetbuilder.com. I find that I can help offset the cost of the project by writing it up properly for a publisher.
