No it will not.

It works with our wired Cisco phone system (IP7962). I would call Plantronics directly and ask them, that’s what I did to make sure it was compatible with our system.

Yes it does. And you should also purchase the APC-43 cable, it’s a plantronics item made for seamless call integration between your Cisco phone and the wireless headset

Yes another model that’s also compatible is at the link below. 1-800-683-5715

I have a crisco phone. The phone do not pick up wireless.

Yes.

It might be compatible but check with a Samsung dealer to be sure.

Bought this for my front office receptionist. She uses it every day and LOVES it. It provides so much freedom and allows her to not be tied to her desk. The sound is good and it reaches throughout our entire office – which is pretty good sized!

This was for a salesman in our office, and he is thrilled with it!

I’ve been using it two months. I have no complaints so far

I work from home and love these!

This work well for our office. The receptionist is busy on the phone and she can walk around and talk at the sometime. No missed calls.

Paid less than half of the regular retail price. Seller even included handset lifter. Installed in 5 minutes and works like a charm. Range is excellent. No longer tied to my desk.

Our people love these. Plug and play. Great distance.

I work in the Pharmacy and this has been a life saver I can move about while still helping customers

First time trying a headset, It’s Great!
