Abstract
A method of providing a user the option to accept an incoming call, play a prerecorded message to the incoming party, ignore the incoming call or forward the incoming call to a separate telephone number is disclosed for use when the user is connected, via the same telephone line, to the Internet. The disclosed invention reduces the number of times the incoming call is transferred which reduces the number of reserves used in processing the incoming call. This reduction frees up system resources and allows overall system resources to be used more efficiently.
