What is CNAM and how does it work?


Intro:

CNAM, also known as "Caller ID Name" is the name of the person or business placing a phone call (limited up to 15 characters). CNAM is the technology that makes your name appear on the recipient's screen. AVOXI’s CNAM is an outbound calling offer only. It is similar to "Display Name" however, display name is for Inbound calls that are then forwarded to an IP/Queue/Team.


All carriers that own numbers have the option to support CNAM. The number carrier you purchase your number from will enter your company name or city into the national database. When you call out from your select number, you will only send the numeric digits. The receiving carrier will then run your digits in the database and display the CNAM or City/State value contained in the national database on the recipient's screen. If someone already has a number stored in their phone book, the CNAM will not show, and the name in your contact list will show. Also, it is possible that if your phone tries to recognize the phone number and suggests who is calling, that might override the CNAM.  In addition, while we always strive to deliver the best customer experience, we can not guarantee that CNAM will always work. 


Why Can’t AVOXI Guarantee CNAM?

CNAM in the United States relies on the name being uploaded to a CNAM database. From here, the name can be retrieved by the termination vendor. This is also why we cannot guarantee CNAM will be displayed on the term handset. CNAM relies on a few items:


  • The term vendor does a look-up of the number and obtains the CNAM information

  • The term vendor does not overwrite the CNAM information with their own information

  • The term user that is being called has a plan on their account that allows CNAM to be pulled and applied on a call to their handset.

  • The term user doesn't have a third-party app that applies its own CNAM information.


AVOXI can ensure the CNAM name is loaded with the vendor CNAM database as well as do third-party look-ups, also known as ‘dips,’ to verify that the term vendor should be able to pull the CNAM information without issue. However, we are unable to ensure a term vendor will pull and apply the CNAM entry on their end. The responsibility is on the term side to complete that task.
