Substituting E.164 Number in Dial String

Between the time a conference is scheduled and when it becomes active, the IP of an
endpoint may change, especially in an environment that uses DHCP. The MCU can be set to
ignore the IP address of a participant when the conference starts. Instead, the alternative
E.164 number will be used.
A new flag, REMOVE_IP_IF_NUMBER_EXISTS, has been added to control this option. This
flag must be manually added to change its value. The values of this flag are:
•YES (default) - The IP address of an endpoint will be ignored.
•NO - The IP address of an endpoint will be used.
Guidelines
• When this feature is enabled, the IP address field of participants in scheduled
conferences and conference templates will be empty.
• In order for the MCU to ignore the IP of H.323 participants, the following requirements
must be met:
—A gatekeeper must be defined.
—The alias of the participant must be defined.
—The alias type must be defined (not set to None).
• If an H.323 gatekeeper is defined but is not connected, the MCU will fail to connect to
H.323 dial-out participants.
Cascaded If this participant is used as a link between conferences select:
•Slave, if the participant is defined in a conference running on a
Slave MCU.
•Master, if the participant is defined in a conference running on the
Master MCU.
It enables the connection of one conference directly to another
conference using an H.323 connection only. The conferences can run
on the same MCU or different MCU’s. For more information, see
"Basic Cascading using IP Cascaded Link” on page 5-3.
