Polycom CMA System Operations Guide

Polycom, Inc.

• Upgrading the system when upgrades/patches are made available. See 

The following are some of our recommendations for administrative best 

practices: 
• Perform the recommended regular maintenance. 
• Except in emergencies or when instructed to by Polycom Global Services 

personnel, don’t reconfigure, install an upgrade, or restore a backup when 

there are active conferences on the system. Many of these operations will 

require a system restart to complete, which will result in conferences being 

dropped. 

• Before you reconfigure, install an upgrade, or restore a backup, manually 

create a new backup of the system settings. Then download and archive 

this backup in the event that something unforeseen occurs and it becomes 

necessary to restore the system to a known good state. 

• For proper name resolution and smooth network operations, configure at 

least one DNS server in your network configuration, and preferably two 

or more. This allows the CMA system to function properly in the event of 

a single external DNS failure.

• Configure at least one NTP server in your time configuration and 

preferably two or more. Proper time management helps ensure that your 

cluster operates efficiently and helps in diagnosing any issues that may 

arise in the future. Proper system time is also essential for accurate audit 

and CDR data. 

As a CMA system auditor, you’re responsible for managing the system’s 

logging and history retention. You should be familiar with the following 

configurations and operations: 
• Configuring logging for the system. These settings affect the number and 

the contents of the log archives available for download from the system. 

Polycom Global Services personnel may ask you to adjust the logging 

configuration and/or download and send them logs.

• Configuring history retention levels for the system. These settings affect 

how much system activity history is retained on the system and available 

for download as CDRs.
