ICE Active Alarms

When ICE environment is enabled in the Collaboration Server, failure to communicate with a required

component triggers the display of an Active Alarm in the System Alerts pane.

SIP TLS: Registration server not
responding
This alarm is displayed when the Collaboration Server does not receive a
response from the OCS to the registration request in the expected time
frame. Possible causes are:
•The Collaboration Server FQDN name is not defined in the OCS pool,
or is defined incorrectly.
•The time frame for the expected response was too short and it will be
updated with the next data refresh. The alarm may be cleared
automatically the next time the data is refreshed.
Alternatively, the OCS Pool Service can be stopped and restarted to
refresh the data.
•The Collaboration Server FQDN name is not defined in the DNS server.
Ping the DNS using the Collaboration Server FQDN name to ensure
that the Collaboration Server is correctly registered to the DNS.
SIP TLS: Certificate has expired The current TLS certificate files have expired and must be replaced with
new files.
SIP TLS: Certificate is about to expire The current TLS certificate files will expire shortly and will have to be
replaced to ensure the communication with the OCS.
SIP TLS: Certificate subject name is
not valid or DNS failed to resolve this
name
This alarm is displayed if the name of the Collaboration Server in the
certificate file is different from the FQDN name defined in the OCS.
Note:
Occasionally this alarm may be activated without real cause. Resetting the
MCU may clear the alarm.
