This is one of the reasons we finally decided to not do VoIP.  We recently 
bought a cordless phone base that can take up to four handsets (we have two 
now), and it would be around $180 to get two more, but I don't want to lock 
myself into HAVING to have a single phone base in the house.  As someone 
else said, you then need to put it on a UPS, which I really don't want in my 
kitchen where the base is.

The other thing I asked them about, which is something you might not have 
thought about, is that your data bandwidth goes way down.  There's a small 
hit all the time, and a greater hit while you're actually on the phone.  I 
already dropped my speed by about half moving from cable to DSL, and I would 
not appreciate giving up even more.

Ypu, the older 2.4Ghz phones can interfere with that.  We got 5.8Ghz 
Panasonics and are incredibly happy with them.
