The lab removes Diversion. modify and add are the other two actions.

Worked example

Remove Diversion Run the CUBE subset rule against the inbound INVITE. Diversion should disappear.

  1. Read the voice class rule.
  2. Run it on the INVITE.
  3. Confirm Diversion is gone.

Vendor menus, ports, and license names change. Confirm before relying on a sentence that is not an RFC.

Fault

The carrier complains about Diversion. debug output still shows the header on the sent INVITE.

The sent INVITE still contains the header the rule was supposed to delete.
