Mode.
Enables the Video Portal to register with a
Gatekeeper or leave it unregistered, i.e. in direct
mode. When registered with a gatekeeper, the
H.323 Status shows
Registered
, the gatekeeper’s
IP address and the port used.
When the registration fails, the Registration
status will be ‘rejected’. Three cases can be
distinguished:
Gatekeeper unreachable
•
; the Video Portal’s
H.323 stack returns this reject message in case
the gatekeeper is down.
Duplicate alias
•
; a system with an identical name
has already been registered.
Authentication failure
•
; Authentication ID and/or
Authentication Password are incorrect.
Selecting direct mode will result in no gatekeeper
registration; hence it is not possible to dial through
the Video Portal via alias names. The H.323 status
shows
Inactive
.
Dialing out via IP
requires the use of
H.323 numbers,
(E.164 aliases and service
prefixes). This means that
the Video Portal must be
registered to a gatekeeper;
select the
H.323
menu item
in the
Configuration
menu.
H.323 Configuration
If the gatekeeper is configured with an
alternative gatekeeper, the status area may
report a registration to the IP address of
the alternative gatekeeper.
In case password is not
set/configured/inserted,
the Video Portal will
still use the Authentication ID
to register with the gatekeeper.
However, when the Authentica-
tion ID is left “unused”, the
System Name field. will be used
to register the Video Portal with
the gatekeeper instead. In case
both the Authentication ID field
and the System Name field
are “unused” the Video Portal
can not be registered with the
gatekeeper.
When registered with
a gatekeeper, the
H.323 Status shows
Registered, the Gatekeeper’s
IP address and the Port used
(see also
Status, H.323
Status
).
IP Address.
Enter the Gatekeeper IP address that
the Video Portal should register to. Leaving this
empty will result in direct dialing without the use of
aliases.
