Stopping All Ports from Taking New Calls
Follow the steps in this section to stop all the ports on a server from taking any new calls. Calls in
progress continue until the callers hang up.
Tip Use the Port Monitor page in the Real-Time Monitoring Tool (RTMT) to determine whether any port is
currently handling calls for the server. For more information, see the Step a.
To Stop All Ports on a Unity Connection Server from Taking New Calls
Step 1 Sign in to Cisco Unity Connection Serviceability.
Step 2 Expand the Tools menu, select Cluster Management.
Integration through PIMG/TIMG units
• The number of ports set up on the phone system is the same as the number
of voice messaging ports on each server in the cluster so that the servers
share all the voice messaging ports. (For example, if the phone system is set
up with 16 voice messaging ports, each server in the cluster must have the
same 16 voice messaging ports.)
• On the phone system, a hunt group is configured to distribute calls equally to
both servers in the cluster.
• The PIMG/TIMG units are configured to balance the voice messaging traffic
between the servers.
• If one of the servers stops functioning (for example, when it is shut down for
maintenance), the remaining server assumes responsibility of handling all
the incoming calls for the cluster.
• When the server that stopped functioning is able to resume its normal
functions and is activated, it resumes responsibility of handling its share of
incoming calls for the cluster.
Other integrations that use SIP
• In Cisco Unity Connection Administration, half the number of voice
messaging ports that are needed to handle voice messaging traffic are
assigned to each server in the cluster. (For example, if 16 voice messaging
ports are needed to handle all voice messaging traffic for the cluster, each
server in the cluster has 8 voice messaging ports.)
• On the phone system, a hunt group is configured to distribute calls equally to
both servers in the cluster.
• If one of the servers stops functioning (for example, when it is shut down for
maintenance), the remaining server assumes responsibility of handling all
incoming calls for the cluster.
• When the server that stopped functioning is able to resume its normal
functions, it resumes responsibility of handling its share of incoming calls
for the cluster.
