Configuring CNAM Replacement

The Oracle Enterprise Communications Broker provides the user with the ability to specify the value of the caller name (CNAM) in the FROM header. A simple use case consists of an enterprise inserting the name of their company into the FROM value, in place of the original caller name. You configures the system to use other policy or routing configurations to determine when to replace a CNAM. The system applies this policy action on SIP requests immediately prior to egress.

To configure CNAM replacement, add the cnam-masking-action action to the affected policy. The Modify Policy / cnam masking action dialog includes two fields.

  • Name—Assigns a name as an identifier to your action.
  • Display name—Defines the text the Oracle Enterprise Communications Broker inserts as the CNAM value in the FROM header.

Note that, if no user name is in the original FROM, the Oracle Enterprise Communications Broker inserts text configured via the CNAM mask and encloses it in brackets per RFC 2822.
