Hi,
I've noticed that most DECT phones out there use bases that only support up to 5 handsets. I've noticed a few Siemens and Panasonic DECT phones that support 6 handsets.
Does anyone have some good suggestions of DECT bases that support up to 6 GAP-compatible DECT handsets?

Thanks,.

I'd go with Panasonic - best DECT phones I have had. (They also sell a relay transmitter if you need to cover a big area.)
