DECT over IP
®
voice data are directly converted into DECT voice data by the base
station. The base stations support the following VoIP codecs:
Configuration
One of the DECT over IP base stations that is installed assumes
coordination and configuration of the DECT over IP functions
(“DECT over IP Manager”, OMM). Select a base station that has a
dependable data link to the Forum 523/524.
Note: You can determine a second base station as additional
DECT over IP Manager (“Standby Device”). If the first
DECT over IP Manager fails, the second base station takes over
this critical function after some minutes and a reset of the DECT
network.
Go to the Telephony: Devices: DECT over IP page in the Con-
figurator. Click on New, to add a DECT over IP base station.
Enter the MAC address of the base station that you have
selected to be the DECT over IP Manager. The MAC address of the
base station is located on its type label. Enter an IP address for
this base station. Confirm with Apply. Now click Change, to
determine the DECT over IP Manager. In standard cases, leave
the Mode in the “IP address from the system DHCP server” set-
ting. Select the desired DECT over IP base station with the MAC
address (IP address) setting. Confirm with Apply.
If the Forum 523/524’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 pro-
gramme (see Local IP Address Configuration starting on
page 149). Also change the Mode setting on the Telephony:
Devices: DECT over IP page to “IP address configured local”
and enter there the configured IP address for the DECT over IP
Manager. All other base stations can be operated using either a
fixed IP address or an IP address assigned dynamically via DHCP.
