Question: Will it work in an office with multiple phone lines?
Document: A small transmitter plugs into the wall, the phone line cord goes into the transmitter, then turn the ClearOne Max phone on snd ...BAM!!!. You've got a wireless conference phone connection ready for prime time!
I have one in my office. Works like a charm. Holds a charge for days and provides wire free audio conferencing. This is a solution to a problem I've had for a while. If they were IP instead of analog, I'd be even happier.
Pro - The Clear One Wireless Phone works as expected. This is the third Clear One I have bought in the past three years. Each one has meet my expectations.I received the product sooner than I expected.Con - None at this time.
The ClearOne Max conference telephone has poor sound quality when compared to Polycom products. Voices are thin and hollow sounding. I purchased 2 of these units and one was full of static - defective.The only positive about these conference telephones is that they are half the price of the Polycom.
I am a consultant with small to med-size corporations. This has come in so handy. Reasons why? 1) Portability - no need for it to take up space. 2) Less accidents - no wires to contend with while hosting your at a meeting/presentation. The only time it's connected is while is charging which can be overnight. This unit has lasted through at least 3 hours of conference call time, not to say it couldnt last longer.
Answer: Yes in our office we use VOIP phones with multiple lines and the phone works great. I have also used it in one of our outstation locations with just two lines and it worked great.
