Introduction
If the DECT handset user is moving, the handset detects that another IP DECT base station has
a better signal strength and, therefore, it starts the hand over process. The media stream from
the IP Phone cannot move to the secondary IP DECT base station, so the primary IP DECT
base station uses the LAN to direct the voice to the secondary IP DECT base station, as shown
in the following figure.
