Abstract

A method for providing a proactive voice mail service wherein a message is recorded by a voice mail server if the customer's phone line is busy or does not answer and the voice mail server then attempts to deliver the message proactively to the customer. The method avoids loop-back charges which limit the usefulness of present implementations of proactive voice mail and allow for a nation-wide proactive voice mail service utilizing a server with toll-free inbound phone lines.
