which case use MCU (compatible)
Refer to the list of Frequently Asked Questions
(FAQ) in the Support section of the web site for
more details about interoperability with
gatekeepers.
Whether a call involves consultation with the
configured gatekeeper also depends on the Port A
and Port B settings. For all incoming calls, and
outgoing calls dialed by address rather than by
E.164 phone number, the gatekeeper will be used
to validate the connection only if the network
port over which the connection is made is
selected here.
Specifies an identifier that the MCU can use to
register itself with the H.323 gatekeeper.
Before the MCU can register any IDs with the
H.323 gatekeeper, it must make a unit-wide
registration.
This field is required for the gatekeeper
registration.
This will have no effect if H.323 gatekeeper usage is
disabled.
If the configured gatekeeper required password
authentication from registrants, check the Use
password box and type the password.
Note that where password authentication is used,
the (Mandatory) H.323 ID to register will be used as
the username.
Specifies an optional group of digits that are
added to the beginning of each conference or auto
attendant's numeric identifier before registering it
with the H.323 gatekeeper.
Conferences and auto attendants registered with a
gatekeeper have a Numeric identifier. The numeric
identifier is a unique sequence of digits entered
from a video-conferencing endpoint to connect
directly to the conference or auto attendant. This
eliminates the need for users to navigate
additional menus or to know the IP address of the
MCU.
To usefully partition the dialing space, you might
need to ensure that all registrations from a single
MCU start with the same sequence of digits.
Using registration prefixes also can benefit large-
scale dial plan changes. For example, you can
change all MCU registrations to begin with "121"
instead of "11" by changing a single MCU
configuration field rather than individually
amending every conference or auto attendant's
