Abstract
A caller verification server receives a verification request message from a calling party via a data network. The verification request is associated with a communication from the calling party to a called device placed via a telephone network. The telephone network is logically separate from the data network. Thus, the verification request message travelling over the data network is said to be “out-of-band” relative to the telephone network. Responsive to receipt of the verification request message, the caller verification server generates a verification message indicating that the associated communication is verified as being from the calling party. The caller verification server sends the verification message to the called device via the data network.
