ABSTRACT:
The present invention provides a call-return process and system, wherein a called party can return a missed call to a caller's private number. A forwarded call is received by a call management system, wherein the forwarded call was originally directed by a caller to a first telephone line associated with a user. The call management system receives call signaling information, including a phone number, associated with the caller. The call management system then determines whether the phone number is a private phone number or a public phone number. If the phone number is private, the call management system notifies the user of the call, and without revealing the caller's phone number to the user, enables the user to return the caller's call.
