What are Call Server Thresholds?

Call server thresholds are designed for monitoring in Cisco environments. They cannot be applied to Avaya or Microsoft components.

Call server performance and status have a powerful impact on Quality of Experience when users make or receive calls. IP phones and voice gateways register with a call server and send keepalives to provide status. The call server handles all aspects of call setup:

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

To help you track call server status, UC Monitor offers two types of call server thresholds to provide more accurate reporting:

Call server thresholds, which are applied to individual servers and generate incidents for Registration Failures and Poor Call Quality.
Call server group thresholds, which are applied to call server groups and generate incidents for Phone Status Changes. An administrator creates call server groups to represent server clusters.
