121
associated numeric identifier.
If H.323 gatekeeper usage is disabled, this field will
have no effect.
Note that if you are also intending to use the
MCU service prefix (see below), Codian
recommends that you set both prefixes to the
same number.
If required, specify a group of digits which the
H.323 gatekeeper may use to identify calls to be
routed to the MCU.
This field is optional. If set, users dialing any
number beginning with this prefix will have their
call directed to the MCU. This might be useful if
you wish to create conferences in response to
unknown E.164 numbers.
Any numbers following the prefix will be
identified by the MCU as a conference or auto
attendant number. For example, if a conference
has Numeric ID "3333" and you have set the
service prefix to be "121", then a user dialing
"1213333" will be connected to that conference.
This field will have no effect if H.323 gatekeeper
usage is disabled.
Note that if you are also intending to use the
Prefix for MCU registrations (see above), Codian
recommends that you set both prefixes to the
same number.
If the MCU is unable to match a call to a
conference or auto attendant, the action for
Incoming calls to unknown E.164 number will be
applied. This is a setting on the
page (see Configuring global
conference settings). This action can be set to
Create new ad hoc conference.
This field controls whether any scheduled
conferences' configured numeric IDs are allowed
to be registered with the gatekeeper.
This would normally be Enabled - by setting it to
Disabled, an administrator can prevent users from
adding to the set of IDs registered with the
configured gatekeeper, even if those users enable
the gatekeeper Numeric ID registration setting for
conferences they control. This may be desired
when working with certain types of H.323
gatekeeper whose behavior in some modes is to
disconnect active calls when the set of registered
IDs changes.
This setting only affects registration of numeric
IDs configured for scheduled conferences -
registration of ad hoc conferences' IDs with the
gatekeeper is controlled by the Register ad hoc
conferences with gatekeeper setting on the
