Question: Will this unit 'pair' up to stream landline into my bluetooth hearing aids?
Document: The product allows you to connect a landline as well as cell phones but it doesn't allow you to receive landline calls via your Bluetooth which is what we need. This unit is therefore useless to us and a complete waste of money. Attempted to contact the manufacturer but the call was not returned.
Works exactly as described! If you have multiple cell phones the unit will allow you to call out or receive calls from any on connected telephones via first available paired cell phone. I disconnected from the landline service then plugged the unit into a jack which connects with all telephones on the system basically allowing them to serve as extensions of the cell phones. Very convenient!
Caller Id works. Bought one for my mom as she doesn't hear to well hooked up her landline plus cell to her clankton ringer with the strobe light. It will wake the dead. Now I can call directly on the cell and she says  it sounds better than talking through the cell phone. The PC connection part works great easy to configure takes care of updating the unit. I give it all thumbs up
We like that this box allows us to set our cell phones down when we come into the house and still answer them from anywhere in the house... and it allows us to integrate both our 1 landline and our 2 cell phones (capability for 3). We bought this unit rather than the lower cost non-landline capable one to see how well it works before cutting over completely to the cells... and we are glad we did, because this unit still is a bit flaky.
The XLink BTTN model conveniently linked my cell phones and landline to ring on my 4 handset cordless phone.The first unit from Amazon was damaged, Amazon cross shipped a replacement. The second unit paired easily with our 3 cell phones and rang through the landline calls.The cell phone caller ID worked with no issues, at first the landline caller ID did not pass through the unit. The DSL filter had been installed backward (line side to phone and phone side to line).
I purchased a Gigaset One unit at closeout sale @ Officemax for a low $$.It's the same unit as the Xlink BTTN bluetooth gateway.
Bought this unit to allow VOIP line on home phone network. So far it has been working great with VOIP line and cell phones. Wish bluetooth range was longer but it is performing as well as current standard allows.
returned the 1st one. the 2nd would work. but needed to be re-linked to cell phones once or twice a month. different cells. unit had latest updates. when unit became a problem linking daily. went to a panasonic phone with bluetooth link.
Never could get it to work reliably. Notably:1) It fouled up my Panasonic wireless system consistently2) when it did work the static was terrible3) the distance on the bluetooth was terrible and signal was lost in several places4) tried updating the microcode, but it doesn't seem to work on Windows 8So what's to like about this unit? In word, nothing!
You say you aren't the only cellphone toting family member in the house? That's okay, because this XLink device will pair with up to three Bluetooth cellphones. You can see which cellphones are connected by glancing at the unit. The blue light corresponding to your phone will light up when connected.4. This XLink device will automatically connect to your cellphone when you bring it within range.Cons:1.
Answer: No, it does not allow you to connect bluetooth headsets/ear pieces/hearing aids to the system.This device allows you to use your landline telephones with your cell phone. This connects to a cell phone via bluetooth and behaves as a handset for your cell phone. When your cell phone rings, any wired or cordless standard landline phones connected to this device will also ring, and you can answer the call from your traditional phone (you can also place a call with your landline phone system that is routed through your mobile phone and thus the cellular network). This particular model (BTTN) allows you connect a standard landline and up to 3 mobile phones to your traditional phones.You might also want to think of it like this - if you abandon your landline service and go mobile only, but you still want to use your traditional phones around the house (instead of holding the cell phone all the time), this is the device for you. It is, in a way, kind of like this product: Echo Logico Retro Handset - Soft Touch - Wired Headsets - Retail Packaging - Black (ELO - BLK - ST) but it is wireless you use your traditional phones just as you always have to make and receive calls.
