Question 1

Will this work with the Panasonic KX-TG6644 6.0 Plus phone set?

Accepted Answer

This Panasonic KX-TGA660B phone works great. If you have 6 phones then you need to go to the base instructions and remove one unit so you can install the new one. ^6 is the max # of phones. Mine were gray and I ordered black. Works great.

Question 2

Is this the COMPLETELY comparable 6th handset for the Panasonic 5 phone KX-TG7645M I'm about to order?

Accepted Answer

Yes it is. My set is KX-TG6645. I don't know about the M at the end. It may have something to do with the color of the Phone. My phone is black. Works great and is easy to set up with your base.
