Operation Tips
!
When a new call fails — check the Zone Definition Table to see what endpoints are
registered in that zone.
!
To avoid confusion when LAN endpoint phone numbers begin with the same numeric
string as service prefixes. You can modify the prefixes in the Gatekeeper and MCU-323
Services Definition Table so that they are unique within the zone.
!
The MCU reserves bandwidth for the total number of participants in this conference
even if not all the expected participants join the conference. To prevent this waste of
bandwidth and MCU-323 resources, we recommend you set an average number of
participants, for example four.
!
Each entry line in the Services Definition Table represents a different type of
conference call using a particular service. Several conferences using the same service
can take place at the same time. A
unique password should be added to the conference
prefix to distinguish it from other conferences.
!
When using data collaboration applications, check to see if the MCU-323 is enabled for
simple T.120 support, or an external T.120 server. If the external T.120 server is
enabled, you must ensure that the T120 server IP address and port are configured.
!
When the Zone Definition Table of the Gatekeeper configuration is open, the
Gatekeeper cannot receive new registrations.
!
When using the H.323 Proxy in a conference take into consideration that the Proxy uses
two calls to the Gatekeeper for each call being set up. This can limit the number of
concurrent calls that are supported.
