Abstract

A method and apparatus for telephony messaging based on a network of packet telephony messaging (PTM) servers. A message is received at an originating PTM server from an originator for delivery to a target device for a recipient. The message is stored at the originating PTM server. The message is routed from the originating PTM server (possibly via a second and subsequent PTM servers) over a first network to a destination PTM server located near the target device. The recipient is notified of the message by the destination PTM server. The message is delivered to the target device from the second PTM server over a second network in response to a request by the recipient.
