Integrating telephony and voice mail routing

摘要

A data processing system comprises call processing logic comprising a voice mail subsystem, or a call management subsystem configured to process voice-over-IP (VoIP) calls, or both a voice mail subsystem and a call management subsystem; service advertisement logic coupled to the call processing logic and operable to send one or more service advertisement messages by unicast to a remote peer data processing system that is also configured with compatible service advertisement logic, wherein the remote peer data processing system is located in a different LAN segment than the data processing system; and each service advertisement message comprises one or more network addresses associated with the call processing logic, and one or more data sets each comprising an identifier value, a first value that indicates that the identifier value is associated with a telephone extension, and a second value that indicates that the identifier value is associated with a voice mailbox.

1. A data processing system, comprising:
first call processing logic, of a first data processing system, comprising both a first voice mail subsystem and a first call management subsystem configured to process voice-over-IP (VoIP) calls; first service advertisement logic coupled to the first call processing logic and operable to send one or more service advertisement messages by unicast to a second peer data processing system that comprises both a second voice mail subsystem and a second call management subsystem, and that is also configured with compatible second service advertisement logic, wherein the second peer data processing system is located in a different LAN segment than the data processing system; wherein each service advertisement message comprises one or more network addresses associated with the first call processing logic and associated with telephone extensions and voice mailboxes, and one or more data sets each comprising an identifier value, a first value that indicates that the identifier value is associated with a telephone extension, and a second value that indicates that the identifier value is associated with a voice mailbox; wherein the second value, provided by the first data processing system, is used by the second peer data processing system to directly transfer a call, without ringing, to the voice mailbox of the first data processing system without transferring the call to the first call management subsystem of the first data processing system for forwarding to the voice mailbox of the first data processing system.
