Use your cell phone through your home phone wiring with bluetooth

Step 2 How all this works

If you have a bluetooth cell phone, you've probably used a bluetooth headset before. The Xlink gateway works sort of like a souped-up bluetooth headset. Instead of an earpiece, the Xlink has a regular RJ11 phone port that you plug a landline handset into, and connects to your cell phone over bluetooth (acting as a 'gateway', duh). For example:

IF: You receive a phone call.
Headset: beeps through the speaker, and answers the call when you press the answer button
Xlink: rings the phone handset's bell/buzzer and answers the call when you pick up the handset

IF: You want to make a call
Headset: You press a button on the headset which activates your phone's voice dial, speak the name and the phone completes the call
Xlink: you pick up the handset (you will actually hear a dial tone just like a landline phone, this is generated by the Xlink) and dial the phone, the cellphone completes the call. If the landline handset has its own speed-dial or other features, you can use these too

In addition, when you get a call the Xlink not only rings the handset, but also transmits the caller-id info to the handset.. but "wait", you say? "My bluetooth headset doesn't show the caller info" Well, the phone does transmit the info, but your bluetooth headset probably just doesn't have a display to show it.. some of them do, though. However, most of the time the phone will transmit the number but not the caller, so it will just show up as "Xlink" in the name field.. still, you get the number which is better than nothing.
