Phone number

Configure the variable that contains the phone number that will be analyzed.

Usually, the variable “source_phone” from the Incoming Call is used as the input variable, but any other variable that contains a phone number can be used.

If the variable containing the phone number is not the “source_phone”, the call attestation information will not be available.
