To add Alerts on bad calls you can use the CDR tab in the Config Tool. Then click on the “Add Button” and you should see the box below
A “bad call” is user dependent. Users might view a “bad call” as a call that has 3% packet loss, but someone else might define it as 1% packet loss. Everyone has their own standards.
Set the Alert for 2% Packet Loss and adjust as needed. If too many alerts for bad calls are received, yet users aren’t complaining, then you might change it to 3% or more.
If you have users complaining about calls that are bad that they didn’t get alerts for, then change to 1% and see what happens.
