The method includes receiving a call from a caller through a telecommunication network, identifying a phone number associated with the call from the caller, and processing the phone number. The method also includes determining if the phone number is associated with a wireless telecommunications device, prompting the caller to input a residential phone number for a landline associated with the caller if the phone number is associated with the wireless cellular telecommunications device, and transferring the residential phone number from the caller using a communications process. The method further includes receiving the residential phone number and storing the residential phone number in association with the phone number into one or more memory locations of one or more databases.
