53.4 Viewing Quality of Experience
The Quality Of Experience page provides statistical information on calls per SRD or IP
Group. The statistics can be further filtered to display incoming and/or outgoing call
direction, and type of SIP dialog (INVITE, SUBSCRIBE, or all).
Note: The Quality Of Experience page is applicable only to SBC calls.
This page provides three pie charts:
Dialog Success Ratio: displays the SIP call and subscribe (SUBSCRIBE) dialog
success-failed ratio.
Dialog Failed Attempts: displays the failed call attempts. This includes the number of
calls and subscribes which were successfully and abnormally terminated.
Dialog Termination Ratio: displays call termination by reason (e.g., due to no answer).
To view Quality of Experience:
1. Open the Quality Of Experience page (Status & Diagnostics tab > Performance
Monitoring menu > Quality Of Experience).
