I haven't tested it myself, but from a quick search of other forums, it appears that you can't have 2 of the same type of Bluetooth device connected simultaneously (e.g., 2 separate headsets), but you can do it with 2 different types of devices (e.g., a headset and an input device like a keyboard).
So you're saying that you want your cellphones to become an extension of your landline? Can your Panasonic phone do that? I thought their Link2Cell technology made it possible for you to use the Panasonic phone as a substitute handset for your cellphone, rather than adding your cellphone as an extra handset for your landline.
Yes, the Link2Cell works as advertised. However, you can only have six handsets registered to each base unit. I decided to purchase a second base plus two more handsets and I am finding that my Razr Maxx will only link to one of the two bases at any given time.
Just curious if there is some way to "trick" the Razr into linking to both Panasonic (KX-TG76) bases simultaneously.
