Need telephone base unit for Plantronics CS50 wireless headset

[Latamster]

I have Verizon Fios at home and just purchased a Plantronics CS50 wireless headset (I use one at work with the network phone there).  I need to buy a base unit for home use that will serve as the "slave" telephone for the Plantronics CS50 wireless headset.  I am concerned about buying a unit that is not compatible with either the Plantronics CS50 wireless headset or my Verizon line (i.e. digital or analog).

Any help on this?

Did you ever find a base unit?  I have a cs50 but my headset and base are no longer communicating.  Plantronics wanted to sell me another for $250.
