7.15 Automatic
Gatekeeper
Discovery
Only certain gatekeepers (PBXes) have support for Automatic gate-
keeper discovery, for example MX-ONE TSW.
Automatic gatekeeper discovery is a method to find a gatekeeper (PBX)
to register to. When this method is used, the IP phone sends a multi-cast
message (Gatekeeper Discovery Request) and waits for a confirmation.
Several confirmation messages can be received.
The phone can send the domain name to inform the gatekeeper which
domain the phone belongs to. The domain name can be received from
DHCP 7.11.2 Data from DHCP on page 30 or from the configuration file.
The domain name provided by DHCP has priority over the domain name
defined in the configuration file.
The identity of the gatekeeper to which the phone is to be registered can
be defined in the configuration file. See data identifier
GatekeeperID
in
the description for CONFIGURATION FILE FOR DBC 42X.
The use, or not, of automatic gatekeeper discovery can be defined in the
configuration file and in the settings menu. By default the phone uses the
value defined in the configuration file.
