Abstract
A telephone network provided with an Internet connection and a call routing and control data base connected to the Internet is further provided with multiple geographically separated voice messaging systems connected to the Internet. Calls through the telephone network may be directed to such voice messaging systems or may be forwarded to such systems. Messages may be deposited in mailboxes in such voice messaging systems and then retrieved from telephone stations located sufficiently near the voice messaging systems as to entail no long distance or time toll charges. Return call service may be provided in a manner to avoid long distance or time telephone tolls through use of the Internet connected data base which routes calls which would incur a toll charge through the Internet.
