A first Internet telephone system 620 attempts to call with a second
Internet telephone system 630 via the Internet 600. However, the second
Internet telephone system 630 is not logged onto the Internet at the time
of the call. In response to the failed attempt to call, the first Internet
telephone system prompts the user to send voice mail to the user of the
second Internet telephone system. This results in a phone call over the
Internet between a voice mail system 610 and the first Internet telephone
system, allowing a greeting to be heard, and a message to be stored. This
message may be subsequently retrieved, either using an Internet telephone
system over the Internet, or using a standard phone over the conventional
telephone network.
