Dial plan
prefix
Specify a group of digits which the H.323
gatekeeper may use to identify calls to be
routed to the ISDN gateway.
This field is optional. If set, users dialing any
number beginning with this prefix will have their
call directed to the ISDN gateway. This might be
useful if you wish to create conferences in
response to unknown E.164 numbers.
This field will have no effect if H.323 gatekeeper
usage is disabled.
Gatekeeper Status
The ISDN gateway also displays brief status information about any registered gatekeepers.
Field Field Description Usage Tips
Gatekeeper
status
Displays the status of the gatekeeper currently
being used by the ISDN gateway.
This will be one of:
● name resolved to <IP address>:
the ISDN gateway has successfully
validated the IP address of the
gatekeeper.
● not in use: there is no gatekeeper in
use
● name resolution in progress: the
ISDN gateway is trying to validate an
IP address or find the IP address that
corresponds to the specified host
name for the gatekeeper.
● retrying name resolution: the ISDN
gateway is again trying to validate an
IP address or find the IP address that
corresponds to the specified host
name for the gatekeeper.
● failed to resolve gatekeeper name:
the ISDN gateway could not find the IP
address of the gatekeeper.
Number of
active
registrations
This number refers to the H.323 ID and the Dial
plan prefix. It also shows whether these
registrations are pending (in progress, but not
fully registered) or active (fully registered).
The number of registrations can therefore be:
0,1, or 2.
