DECT over IP

In order to achieve optimal network coverage, a DECT network

with several DECT base stations can be operated. A DECT network

is comprised of DECT terminals connected with the next respec-

tive base station (network cell). For users of a DECT terminal, the

handover from DECT base station to base station is completely

transparent. Even during a conversation, users are switched from

one network cell to the next without any interruption. Administra-

tion of DECT terminals is done centrally via the Forum 523/524

Configurator in the Telephony: Devices: DECT Phones menu.
