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.
The flag, REMOVE_IP_IF_NUMBER_EXISTS controls 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 if an E.164 number (or other) exists.
●NO - The IP address of an endpoint will be used.

Guidelines for Substituting E.164 Number in Dial String

●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:
Encryption Select whether the endpoint uses encryption for its connection to the
conference.
Auto (default setting) indicates that the endpoint will connect according to the
conference encryption setting.
Cascaded (IP Only) 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.

Name
(Dial-out SIP Only)
When Multi Level Precedence and Preemption is used, this is the Precedence
Domain Name for the participant.

Precedence Level
(Dial-out SIP Only)
When Multi Level Precedence and Preemption is used, this is the Precedence
