`ABSTRACT
`Methods, systems and programs for instant voice messaging
`over a packet-switched network are provided. A method for
`instant voice messaging may comprise receiving an instant
`voice message having one or more recipients, delivering the
`instant voice message to the one or more recipients over a
`packet-switched network, temporarily storing the instant
`voice message if a recipient is unavailable; and delivering the
`stored instant voice message to the recipient once the recipi(cid:173)
`ent becomes available.

`
`BACKGROUND OF THE INVENTION
`
`1. Technical Field of the Invention
`The present invention generally relates to Internet tele(cid:173)
`phony (IP telephony). More particularly, the present inven(cid:173)
`tion is directed to a system and method for enabling local and
`global instant VoIP messaging over an IP network, such as the
`Internet, with PSTN support.
`2. Description of the Prior Art
`Traditional telephony is based on a public switched tele(cid:173)
`phone network (i.e., "PSTN"). In the PSTN, a telephone
`terminal is electrically connected to a conventional or legacy
`switch. The telephone terminal and the legacy switch com(cid:173)
`municate via a proprietary protocol, which may be different
`depending on the vendor of the legacy switch. Circuit switch(cid:173)
`ing provides a communication path (i.e., dedicated circuit) for
`a telephone call from the telephone terminal to another device
`over the PSTN, including another telephone terminal. During
`the telephone call, voice communication takes place over that
`communication path.
`An alternative to the PSTN is Voice over Internet Protocol
`(i.e., "VoIP"), also known as IP telephony or Internet tele(cid:173)
`phony. In the IP telephony, a VoIP terminal device is con(cid:173)
`nected to a packet-switched network (e.g., Internet) and voice
`communication from the VoIP terminal device is digitized,
`packetized and transmitted over the packet-switched network
`to a destination VoIP terminal device, which reconstructs the
`packets and audibly plays, stores or otherwise processes the
`transmission. The VoIP terminal device may be a VoIP tele(cid:173)
`phone or a general-purpose personal computer (PC) enabled
`for IP telephony. More specifically, the PC is programmed
`with the software and equipped with audio input/output
`devices ( e.g., a combination of microphone and speaker or a
`headset) to serve as a VoIP terminal device. The PC so enabled
`and equipped will herein be referred to as a VoIP terminal
`device or a VoIP softphone.
`FIG. 1 is an illustrative example of a prior art IP telephony
`system 100. The IP telephony system 100 comprises a packet(cid:173)
`switched IP network 102, such as the Internet, which trans(cid:173)
`mits VoIP traffic from and to a plurality of terminal devices
`104, 106 and 110. Terminal device 104 is a VoIP softphone 55
`that is enabled forIP telephony over the network 102. Termi(cid:173)
`nal device 106 is a VoIP telephone, which is connected to the
`network 102 via a softswitch 108. The VoIP softswitch 108 is
`disposed on the packet-switched network ( e.g., Internet) 102
`between an origination terminal device (such as VoIP soft- 60
`phone 104) and a destination terminal device (such as VoIP
`telephone 106), and routes packets over the packet-switched
`IP network 102. The softswitch 108 may also manage and
`perform administrative functions for the terminal device or
`devices (e.g., VoIP telephone 106) to which it is connected. 65
`Whether the terminal device is a VoIP soft
`telephone 106, the terminal device is c
`
`2
`network 102 via a networking standard such as Ethernet,
`Bluetooth, IEEE 1394 (also known as "Firewire"), IEEE
`802.11 (also known as "WiFi"), or networking over serial
`communication channels such as the Universal Serial Bus
`(i.e., "USB"). Data communication over the network then
`takes place using a connection protocol, e.g., transfer control
`protocol/Internet protocol (i.e., "TCP/IP").
`Further regarding FIG. 1, terminal device 110 is a legacy
`telephone that is connected to a legacy switch 112 for ( circuit-
`10 switched) voice communications over the PSTN 116 with
`other terminal devices. A media gateway 114 may be pro(cid:173)
`vided between the legacy switch 112 and the packet-switched
`network 102 to enable IP telephony between the legacy tele(cid:173)
`phone 110 and a VoIP terminal device, such as a VoIP soft-
`15 phone 104 or VoIP telephone 106. More specifically, the
`media gateway 114 converts the audio signal carried over
`PSTN to packets carried over the packet-switched IP network
`102. In addition, a media gateway 118 may be disposed over
`the PSTN 116 and connected to a softswitch 120 to convert
`20 the audio signal from the legacy telephone 110 to packets
`routed over the IP network 102 via the softswitch 120.
`Voice messaging in both the VoIP and PSTN is known.
`More specifically, the foregoing systems may be provided
`with a facility to allow users to leave voice messages for
`25 recipients, which is a feature that is familiar to anyone who
`uses a telephone. Conventionally, leaving a voice message
`involves dialing the recipient's telephone number (often
`without knowing whether the recipient will answer), waiting
`for the connection to be established, speaking to an operator
`30 or navigating through a menu of options, listening to a greet(cid:173)
`ing message, and recording the message for later pickup by
`the recipient. In that message, the user must typically identify
`himself or herself in order for the recipient to return the call.
`Instant text messaging is likewise known. More specifi-
`35 cally, a user is provided with a client terminal, which is
`typically a general-purpose PC programmed with instant text
`messaging software and in data communication over an IP
`network with an instant text-messaging server. The instant
`text-messaging server presents the user, via the client termi-
`40 nal, with a list of persons who are currently "online" and
`ready to receive text messages on their own client terminals.
`The user then uses the client terminal to select one or more
`persons to whom the message will be sent and types in a text
`message. The text message is sent immediately via the text-
`45 messaging server to the selected one or more persons and is
`displayed on their respective client terminals.
`However, notwithstanding the foregoing advances in the
`VoIP/PS TN voice communication and voice/text messaging,
`there is still a need in the art for providing a system and
`50 method for providing instant VoIP messaging over an IP
`network. More particularly, there is a need in the art for
`providing local and global instant voice messaging over VoIP
`with PSTN support.

`The present invention is directed to a system and method
`for enabling local and global instant VoIP messaging over an
`IP network with PSTN support.
`FIG. 2 is an exemplary illustration of a local instant voice
`messaging (IVM) system 200 according to the present inven(cid:173)
`tion. The instant voice messaging system 200 comprises a
`local IVM server 202 that provides the core functionality for
`enabling instant voice messaging with PSTN support accord-
`55 ing to the present invention. The architecture of the local IVM
`server 202 will be described in detail hereinbelow with ref-
`erence to FIG. 4. According to the exemplary IVM system
`200, the local IVM server 202 is enabled to provide instant
`voice messaging to one or more IVM clients 206 and 208, as
`well support instant voice messaging for PSTN legacy tele(cid:173)
`phones 110. It is noted that although FIG. 2 depicts one of
`each IVM client 206, 208 and legacy telephone 110 for clarity
`and brevity, the local IVM server 202 is enabled to support a
`plurality of each of the foregoing IVM clients 206, 208 and

`204. The network 204 may be a local area network (LAN), a
`wide area network (WAN), or the like, which supports both
`wired and wireless devices. The exemplary IVM client 208 is
`a VoIP softphone, the architecture of which will be described
`in detail hereinbelow with reference to FIG. 3. A microphone
`212 is connected to the IVM client 208 and enables the
`recording of an instant voice message according to the present
`invention into an audio file 210 for transmission to the local
`IVM server 202 over the network 204. An input device 218
`( e.g., a keyboard) is connected to the IVM client 208 to select
`one or more recipients that are to receive the recorded instant
`voice message. Although not depicted in FIG. 2, the input
`device 218 may include a trackball, digitizing pad or mouse,
`or the like. A display device 216 is connected to the IVM 15
`client 208 to display instant voice messages recorded and/or
`received by a userofthe IVM client 208.Anaudio device 214,
`such as external speaker, is connected to the IVM client 208
`to play received instant voice messages. It is noted that the
`microphone 212, audio device 214, display device 216 and 20
