In general a DECT PP (Portable Part, ie handset) can hold subscriptions
for many FPs (Fixed Parts, ie base-stations), but is only active on one
at any given time, and you have to manually switch to the other
subscriptions, much like a dual-band GSM phone.

The other case is a multicell DECT system, which may consist of several
RFPs (Radio Fixed Parts) all wired back to the central FP. It's
logically a single base station that just happens to have several
geographically dispersed DECT radio transmitters. A DECT PP will
seamlessly handover between RFPs on its registered FP in exactly the
same way GSM handsets do when you move between cells.

Personally I use a 4 line BT Airway DECT system. It's expensive and
ugly, but performs excellently. As an added advantage, it's exceptional
at both BT and cable CLI, and can present the information to a PC via
its serial port or over the air to one of the Airway wireless data boxes.
