Some hardphones, softphones, and phone numbers are capable of displaying a caller’s name on the screen during an incoming call. You can set up a caller name (your company name, business name, or a custom name) for calls to such phone numbers or endpoints.
Calls to endpoints
For outbound calls to endpoints that are registered with softphones or hardphones and have caller ID name support, you can set up the caller name using the caller_name attribute in the HTTP API. Refer to our API reference guide on making a call for details.
For inbound calls that are redirected from your Plivo DID to an endpoint registered to a softphone or hard phone with caller ID name support, you can make use of the “callerName” attribute available in the dial XML element.
Calls to phone numbers
We support the CNAM feature only for calls made to US phone numbers. A phone number (Plivo DID) must be registered in the CNAM database for such calls to display a custom name.
