Supervisors must have permission to listen in on a user extension. Listening in permissions are granted in privacy groups, see also
6.3 Privacy groups

Make sure you comply with European and national laws and regulations on call monitoring
Some general guidelines for listening in for training and coaching purposes are:

Employees should be informed that they can be listened to, how this work and what the purpose is

Listening in can only be used for training and coaching purposes and should not be used for other purposes

Only routine calls with business content intended for the company are listened in, e.g. calls to main company, service or information numbers

Employees should be notified when a supervisor is listening in. In Enreach Contact, this is done by playing a notification to the relevant agent announcing that a supervisor is starting to listen in

Calls that were listened in to, have to be evaluated immediately with the colleague concerned
