Caller Name Delivery (CNAM)

Caller Name Delivery (CNAM) is a telecommunication feature that provides the calling party’s name information to the recipient. While CNAM services are predominantly used in the United States, their availability and implementation can vary across different countries and operators.

DIDWW offers CNAM services categorized into two types:

• CNAM IN: Delivers the caller’s name to the customer’s endpoint specified in trunk settings.

• CNAM OUT: Assigns a caller’s name to the DID number, which is displayed to the receiving party during the call, provided the destination operator performs a CNAM lookup.

Note

The effectiveness of CNAM OUT depends on the destination operator. If the destination operator performs a CNAM lookup and retrieves the value from the CNAM database, the assigned caller name will be displayed to the called party.

Use the following options to manage your CNAM:
