The VoIP monitor determines if the Mean Opinion Score (MOS) for an IP SLA device 'falls out' of the configured threshold. If the returned value exceeds the defined threshold, the monitor is considered Down .

Provide a unique name and description for the monitor, then configure the following:

  • Select the acceptable MOS threshold on a scale from 1 to 5, where 5 denotes perfect call quality.
    • Check MOS values of all jitters configured on the device . Enable this option to include all of the device RTT entries to check MOS performance thresholds.
    • Only check MOS if tag contains . Enable this option to limit the device RTT entries that use this MOS performance threshold. When enabled, enter all, or a portion, of the tag used to identify the source and destination devices.

Additionally, you can set the timeout and number of retries if desired.
