Recently one of our customers asked, "Why is Caller Name not displaying correctly to my customers and what can I do about it?"
When you receive a call in the USA, you can see the phone number and name of the person calling you, thanks to the Caller ID and Caller Name features. These features work by using a system called Automatic Number Identification (ANI) and Automatic Name Identification (ANI).
When someone calls you, their phone company sends your phone company their phone number and name, along with other details about the call. Your phone company then displays this information on your phone or Caller ID device, so you know who is calling you.
However, the transmission of the caller's name is not always reliable because it is not mandatory, and it depends on the service provider's configuration and the caller's consent.
All is not lost, however. Cisco just shared with Virtual Guardians a way to impact multiple carriers at the same time. You can register for a free service that verifies your phone numbers to them.
