DECT over IP
®
Configuration
83
Transmission of telephony signalling and voice data via TCP/IP offers usage of
existing network infrastructure and an increase in range using suitable methods.
VPN connections, for example, can be used for data links to provide service to
remote or hard-to-reach locations.
8.1.2 Features
All DECT over IP base stations can be connected to a CAT5 Ethernet cable with a
10/100 Base T. Power is supplied either via Power-over-LAN (IEEE 802.3af ) or via an
additional power supply unit.
Please note:
The WLAN function of the RFP 42 is activated only when con-
nected to the 100 Base T.
DECT terminals offer all system telephony features. DECT telephones supporting
the GAP standard can also be operated. Transparent GAP device handovers are
supported. DECT encryption of calls can be deactivated for the RFP 32, RFP 34 and
RFP 42 if desired.
VoIP audio communication between the DECT over IP base station and the
Aastra 800 is made via the RTP/RTCP protocol. RTP voice data are directly con-
verted into DECT voice data by the base station. The base stations support the
VoIP codecs G.711, (uncompressed) as well as G.729 (compressed).
8.2
Configuration

setting. Confirm with
Apply
.
If the Aastra 800’s DHCP server is not configured for static address assignment, you
first need to configure the IP address of the DECT over IP Manager with the help of
an additional program (see
Local IP Address Configuration
starting on page 89).
