The maximum number of monitored lines is 50 but you should consider bandwidth. The maximum may also be determined by the number of line buttons on the user's phone.

The monitoring service only works with a user's primary device.


From the customer view in, go to Users, and select the user you want to modify.


Select Calling, choose Advanced Call Settings, and then go to Monitoring.


Choose from the following:

  • Add Monitored Line
  • Add Call Park Extension

Choose whether you want this user to be notified about parked calls, search for the person or call park extension to be monitored, and then click Save.


The monitored lines list in Control Hub corresponds with the order of monitored lines that show on the user’s device. You can re-order the list of monitored lines at anytime.


The name that appears for the monitored line is the name entered in the user or workspace's Caller ID First Name and Last Name fields.
