What are Call Server and Call Server Group Thresholds?

Call server performance and status have a powerful impact on user quality of experience when making or receiving calls. IP endpoints register with a call server and send keepalives to inform the system of their status. The call server handles all aspects of call setup, including:

• Sending dial tones and ringing or busy signals
• Routing calls
• Cleaning up resources when a call is complete

To help you track registration failures and incidents of poor call quality, two types of call server thresholds are available. The two different threshold types provide more accurate incident reporting:

• Call server thresholds are applied to individual servers.
• Call server group thresholds are applied to call server groups that represent your server clusters.

Note: Call server thresholds are designed for monitoring Cisco environments. They are not applicable for Microsoft or Avaya environments.
