Call monitoring

It is an extension’s attribute both to monitor other extensions and to be monitored by other extensions. When so enabled, an extension monitors all the extensions which are enabled to be monitored.

When creating or editing an extension, you can allow it to monitor or to be monitored:




To monitor another extension:

  1. Insert *33 before the extension's number.


If you either try to monitor an extension that can't be monitored, or try to monitor without monitoring properties, you'll get a Forbidden SIP error
