There is a little bit of clicking sort of like handshaking to start.

Great product but a bit difficult to synch with phone systems

My phone reception did not improve one bit.

Took a little bit to sync it up but after that, no worries.

I was a bit apprehensive about this purchase because some reviews mentioned the setup instructions were incomplete or vague about how to set it up

Great product but a bit difficult to synch with phone systems

I had previously bought a new set of Panasonic phones for my hotel and while they are great, there was very limited distance and a bit of interference before buying this.

A bit confusing about installation instruction, but it was just a few easy steps.

Just as I spected ...Thank you
