Description
In a gateway call, the prefix can be followed by a
Gateway Session Profile or by another format
that can be read by the gateway.
The dialing format depends on the call type as
follows:
•
Conference (multipoint): [H.323 prefix]
[Conference/Meeting Room numeric ID/
name]
• Gateway session (point to point): [H.323
prefix] [gateway service prefix] [gateway
delimiter] [gateway information]
Notes:
•
This mode is dependent on the gatekeeper's
implementation as the gatekeeper may not
allow multiple registrations from different IP
addresses.
• Board Hunting is the default mode. It is not
recommended to use Board Hunting with
Forwarding. If both are selected, Forwarding
overrides Board Hunting settings.
• Register as a Gateway – Select this mode when
using a Cisco gatekeeper.
In this mode the gatekeeper is defined as a
gateway. A gateway prefix is usually manually
registered with the gatekeeper and the IP cards
use the same prefix to register with the gateway.
With a Cisco gatekeeper that supports this
mode, the MCU is registered as an
H.320-gateway and it requires the dialing string
to start with the prefix as with Board Hunting.
Note: In current Cisco implementations when
there is more than one IP card in use, the
gatekeeper selects one of the boards that are
registered with the dialed string. Thus the system
does not automatically forward the calls to an
available card.
