The 3CX supports adding a "call-by-name" option to a Digital Receptionist, and when called, the system will prompt the caller to enter the first three letters of the party's last name. Before the system routes a match for a dial by name entry, it needs to have the extension's voicemail prompt set up for a self-identification message. Otherwise, it will just tell the caller that there is 'no match found.'
We recommend that new users call their voice mail by dialing 999 and entering the pin sent in the welcome email. Then press option 9 for the mailbox options and five and record their full name as the self-identification message. It is also an excellent time to record a greeting for their mailbox.
