I don't know if this is any help to you, but I looked on the Voip-info.org website about VoIP GSM gateways, and they talked about a product called the Dock-n-Talk. I have one of these devices myself hooked up between my cell phone and a regular phone and it works quite well. Data can not be transferred over the line such as faxes (that is at the carrier's end) but voice will work.
Something to keep in mind. If you need any information on the Dock-n-Talk let me know, My company sells them. Cheers!

We've been playing with that "really cheap" Taiwanese gateway: Suncomm SC-385. They beat everybody by price, but product simply is not mature. They have issues with one stage dialing and caller id transmitting from GSM to Voip. So, always evaluate product before buying. And Bruce is right, there is no local pickups.
