Hi Claudius, I know this isn't exactly an answer to your question, but I think I've heard about a module for Asterisk that connects to a cel phone using bluetooth. When a call comes in on the cel phone, Asterisk answers it. When you want to place a call out, Asterisk uses the cel phone.
My guess is that it attaches like a handsfree headset. This might get you started. http://www.voip-info.org/wiki/view/Asterisk+Bluetooth+channels On a side note, this is a borderline biz question since "Where do can I buy?" type questions tend to solicit answers from resellers etc. It sounds like you've got an interesting project on the go. Good luck with it.
