Service Mode
(cont.) • Board Hunting – In this mode, the MCU is
registered with the gatekeeper using the Network
Service prefix. In addition, all the IP cards that
are defined in the same Network Service register
with the gatekeeper with the same prefix.
When using the Network Service Prefix for
dialing, the IP call that reaches the gatekeeper is
forwarded to first available IP card on the MCU
according to the cards registered with the
gatekeeper for the Network Service whose prefix
was used. In this mode, the dialed string must
begin with the IP Service prefix and can be
followed by the conference Numeric ID. For
example: [H.323 prefix] [Conference/Meeting
Room numeric ID/name].
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:
[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.
