- Endpoint 51a is an office phone, and endpoint 51b may be one or more of a home phone, PC, cell phone, IP phone and/or PDA.
- user 48 may desire to be notified when a call is received at a phone associated with user 48 (e.g., office phone 51a and/or endpoint 51b) .
- a phone associated with user 48 e.g., office phone 51a and/or endpoint 51b
- user 48 is notified about any call received at his office phone 51a, as the call is received and while the office phone is ringing. Such notification may be received by user 48 at endpoint 51b.
- multimedia server 42 may send a voice call, instant message, SMS text message and/or other type of message to the user's phone or other associated endpoint, such as a PDA or PC, informing user 48 that a call is being received.
- multimedia server 42 is able to find the endpoint or device via which the user is available, and send the notification to this device.
- user 48 may call multimedia server 42 and may be identified by presence server 49 by his presence on the phone or other device.
- multimedia server 42 may notify the user through IM or SMS text messaging to a cell phone, that a call is being received and may invite the user to call into multimedia server 42.
- User 48 may move freely between various endpoints during the course of the day, such as the user's office phone, cell phone and home phone, re-establishing his presence on any desired endpoint.
- the presence on the new device is recognized by multimedia server 42, and the user is associated with his presence.
- the call and the IM or other notification messages may be routed to user 48 while freeing the user to roam freely between his endpoint devices.
- the system may send multiple identical notifications to a given user; for example, one may be sent to the user's SMS connection and another to the user's IM connection.
- FIGURE 3 illustrates a method for communicating messages, in accordance with a particular embodiment of the present invention.
- the method begins at step 100, where a request for connection with a called party (e.g., user 48) associated with a second client (e.g., IP Phone 51a) is received from a calling party (e.g., user 60) associated with a first client (e.g., endpoint 62).
- a calling party e.g., user 60
- a first client e.g., endpoint 62
- the calling party may be using a telephone to place a telephone call to a called party, while the called party is away from his office. In the past, this would typically result in the calling party being transferred to a voicemail system associated with the called party.
- the calling party would have the option to leave a message, or hang up.
- the called party would not be aware that the calling party was attempting to reach him, unless and until the called party checked his voicemail for messages, and/or received a caller ID history of incoming calls.
- the called party may be notified that a request for connection (e.g., a telephone call) has been received, while the calling party is still on the line.
- a request for connection e.g., a telephone call
- the called party may be "logged on" to a presence server, and the presence server may know how to reach the called party, using a third client (e.g., endpoint 51b), other than the office phone of the called party.
- the third client may be a text enabled client (e.g., an Instant Messaging client) of the called party.
- the presence server may transmit a message to the called party that a calling party is trying to contact the called party, quickly after the request for connection is received. For example, while the calling party is still listening to ring tones, the presence server may notify the called party of the telephone call, using a text message transmitted to the third client.
- the called party may receive a message that an incoming call was received at the called party's work telephone.
- the message may include the telephone number of the calling party, to give the called party an idea of the identity of the calling party.
- the message may include the name of the person or organization associated with the first client .
- Such information may be obtained using "Caller ID'" type information recorded by the telephone network operator (e.g., telephone company) .
- the presence server may use the telephone number of the calling party to find the identity of the calling party by searching stored contacts of the called party (e.g., a Microsoft OutlookTM account of the called party) or a directory (e.g., Microsoft Active DirectoryTM) .
- the called party may receive a message, such as "a call from Joe Smith (214) 555-1212 is being received at your work telephone.”
- the called party may be given the opportunity to provide connection processing instructions to the presence server. For example, using DTMF keys of the third client, the called party may instruct the presence server regarding how to process the request for connection.
- the called party may be given several options for processing the request for connection. One option may be to simply allow the calling party to be transferred to the voicemail account of the called party.
- the called party may use this option if the called party is involved in an important meeting, or if the called party does not desire to communicate with the calling party (perhaps based upon the identity of the calling party) at that time .
- the called party may also be given the option to transfer the calling party to another voice enabled client of the called party.
- the called party may instruct the presence server to connect the calling party with a cell phone of the called party.
- the called party' may instruct the presence server to establish a voice connection between the first client and the third client. This feature allows the called party to selectively intercept and reroute calls intended for his work telephone, to another device, or client, of the called party.
- the called party may use an IM device to issue call control commands that govern the routing of the incoming call.
- multimedia server 42 includes a bridge/translator that receives text commands from the called party regarding the desired treatment of the call .
- the bridge in multimedia server 42 translates these text commands to the specific call control protocol used in the system (e.g., SIP, H.323, ISDN, etc.) and uses these commands to control the routing of the call.
- the called party establishes IM communication with a proxy of the multimedia server.
- the proxy communicates on behalf of the called party.
- the proxy may also establish a voice communication path between the calling party and the proxy.
- the called party may also use the proxy to control the call, using IM.
- the called party may use a particular indicator to notify the proxy that a call processing instruction will follow.
- the indicator may be a "!c" typed at the beginning of an IM, that indicates a call processing instruction will follow.
- the called party may also be given the opportunity to establish a text connection with the calling party. For example, if the called party is attending a meeting or seminar, and a voice conversation is not practical, the called part may instruct the presence server to allow the called party to communicate using text messaging.
- the calling party may still communicate using voice communication (i.e., a hybrid voice/text communication session) , or the calling party may elect to communicate with the called party using a two-way text communication path, if the first client is text enabled.
- a multimedia server may use text-to-speech (TTS) and/or speech-to-text (STT) to accommodate a communication session between the calling party and the called party. If the called party instructs the presence server that the called party would prefer to communicate using text messaging, the presence server may notify the calling party that the calling party is only available to communicate using text, and the presence server may give the option to the calling party to communicate using text or voice.
- TTS text-to-speech
- STT speech-to-text
- the presence server may act as an intermediary, and: (i) translate text received from the called party to speech, and play the speech over the telephone of the calling party; and/or (ii) translate speech received from the calling party to text, and display such text to the called party;
- the calling party may be advised to speak slowly to facilitate the recognition of the spoken message by the STT.
- the called party may elect to listen to the voice of the calling party (if the third client is able to play voice communications), but respond using text. This scenario may be used where the calling party is in a meeting, but has a text messaging client with voice capabilities, and the called party can discreetly listen to the calling party using, for an example, an earpiece.
- the connection processing request is received from the called party.
- the connection processing request may be one or more of a number of alternatives selected by the called party. Although all such alternatives cannot be described fully herein, a list of representative examples are described below, and include: • Transfer the calling party to voicemail. • Transfer the calling party to voicemail, and convert the contents of any voicemail to text and transmit the text to the third client approximately in real-time. • Transfer the calling party to voicemail, convert the voicemail to text, and transmit the text message to the third client after the calling party disconnects. • Establish a two-way voice connection between the first client and a third client. • Establish a two-way voice connection between the first client and another client selected by the called party.
- This embodiment allows the called party to use the IM to communicate via hybrid voice/text with the calling party. Then the IM is used to redirect the call to another endpoint .
- One aspect of this embodiment is the fact that the called party can use the IM for communication to the called party and to the multimedia server. For example, by starting a line with a special tag "!c" it signifies to the IM server that this line is a command for the multimedia server rather than a message that needs to be TTS to the called party.
- the calling party communicates using voice.
- the multimedia server receives the voice of the calling party, and coverts it to text, then delivers the text message to the called party.
- the called party responds using text.
- the multimedia server converts the text to speech, and delivers the voice message to the calling party.
- the presence server processes the request for connection in accordance with the connection processing instruction received from the called party. Assuming that the calling party is communicating using a POTS telephone, and the called party elects to receive and transmit text messages only, the communication session may proceed as described immediately below. After notifying the calling party that the called party will communicate using text, the presence server may solicit a message from the calling party.
- the presence server may receive the voice message from the calling party, convert it to a text message, and deliver the text message to the called party, approximately in real-time (taking into account the time it takes to receive, convert to text, and transmit the text to the third client) . While the called party is receiving the converted text message, or shortly after receiving the entire text message, the called party may begin typing a response.
- the presence server may receive the text message response from the called party, approximately in real-time.
- the multimedia server may be configured to convert the text message to speech, and transmit the message to the calling party as it is being received, approximately in real-time.
- the multimedia server may transmit converted voice messages to the calling party only as full sentences or full paragraphs are received from the calling party.
- the multimedia server may transmit the converted voice message to the calling party, only after receiving an indication from the called party that the response is complete.
- the text message from the called party will not be delivered to the multimedia server until the called party is complete with the response.
- the called party will be allowed to type, modify and/or edit the response, and send the text message to the multimedia server when it is complete. In this manner, it may be similar to typing a response to a text message or email, and pressing "send" when the message is complete.
- the multimedia server may be configured to enhance the converted voice message before it is delivered to the calling party.
- the multimedia server may incorporate feminine or masculine characteristics, respectively, into the voice message that is delivered to the calling party.
- the multimedia server may include a database that stores voice characteristics associated with the called party, to allow the converted voice message to approximately mimic the called party's voice. This feature lends more authenticity to the voice message that is transmitted to the calling party.
- the voice characteristics stored by the multimedia server may be sophisticated voice spectrum characteristics that allow the presence server to approximately reproduce the voice, tones, and/or inflection common to the voice communications of the called party.
- Sophisticated software associated with the multimedia server may also be used to generate authentic tones and voice inflections based upon punctuation, words and other content associated with the text message received from the called party.
- the calling party may be provided with the ability to convey messages to a text-based client of the called party, using DTMF keys.
- a user of any telephone including POTS telephones may communicate text, numeric, and/or voice communications to a called party that is using a text-based client.
- the teachings of the present invention further allow a called party to employ rule-based logic to define the interaction of the calling party, and a text-based client of the called party.
- the called party may predefine his interaction with a multimedia server and/or the interaction between the calling party and the multimedia server.
- the called party and/or an administrator of the multimedia server may configure the multimedia server to handle particular communications in a particular manner.
- the message may be automatically forwarded to the called party, or the called party may be notified as the urgent message is being received.
- all non-urgent messages may simply be forwarded to a voicemail account or handled otherwise.
- the called party and/or the administrator may configure the multimedia server to locate and notify the called party, and/or forward messages intended for the called party, to the called party, only if the message is received from a predetermined list of individuals.
- the called party may configure the multimedia server to notify the called party if a message is received (or is being received) from the called party's wife or other family member, supervisor at work, and/or any other individual that the called party would like to have "priority" in the handling of requests for connections and/or messages intended for the called party.
- Existing voicemail systems often ask the calling party to specify the priority of a message after the message has been recorded.
- the system of the present invention may prompt the caller to specify the priority of the message, as or soon after the request for connection is received (but before the message is completed) , such that the rule-based logic discussed above may be employed for determining how to process the incoming request for connection and/or associated messages from the calling party.
- the teachings of the present invention are not limited to requests for connection and/or messages received from voice-enabled clients, only.
- the multimedia server may be configured to receive electronic mail messages intended for the called party. The electronic mail messages may be converted to voice, and delivered to a voice-based client of the called party.
- the electronic mail message may be forwarded to such client.
- the multimedia server may take into account a "priority" of the e-mail message (e.g., urgent, or non-urgent).
- the multimedia server may take into account the sending party of the electronic mail message, in order to determine whether or not to alert the called party of the message and/or deliver the message (in voice and/or text format) to the called party.
- a voicemail system may be enhanced with a presence proxy, for its user community. Another example of the operation of such a system is described more fully below.
- a caller from any phone calls a person who is away from his office.
- the caller is transferred to the enterprise voicemail system that plays the typical prompt "Hello, this is Joe. I'm away from the office, please leave a message at the sound of the beep" .
- a presence proxy server determines if Joe is logged on to an IM enabled device. If Joe is not logged on to such a device, the system continues to record a voicemail message for Joe. However, if Joe is logged-on to an IM device, a connection (as detailed below) is established between the caller and Joe's IM system, enabling Joe and the caller to exchange information.
- Joe's corporate directory helps resolve the mapping between Joe's extension and his IM address/user name.
- a voicemail message when a voicemail message is left for Joe, it is translated into text using speech recognition and rendered to Joe's IM client.
- the caller can enter his callback number via DTMF keys.
- the system may use rule-based script, and decide to establish voice connectivity between the voicemail server and Joe's IM device. The rules may be based on caller ID information, the capabilities of Joe's IM device (e.g. whether it is voice enable), or Joe's willingness to engage in a voice call at any particular time. For example, a user in a meeting may be willing to engage in a text IM messaging and not in a voice communication.
- the caller is queried whether the message is urgent, and the IM server is invoked only to convey urgent messages.
- This option can be configured as one of the rules described above. If Joe elects to communicate via text, the voice messaging system utilizes a TTS server to convey his message to the caller. To make the communication more authentic, the system stores Joe's voice characteristics in the directory. These parameters are applied to Joe's TTS session at the TTS server and help convey Joe's message to the caller with Joe's simulated voice.
- the integration between the multimedia server and the IM proxy is used to expedite the delivery of urgent voicemail messages to end users.
- the system exploits the fact that users are not always logged-on to their electronic mail, but are typically logged-on to their IM device.
- the multimedia server invokes the IM proxy to determine if the user is logged-on to his IM client. If he is, an IM is sent to him alerting him that he has received an urgent e-mail.
- the system can use script-based logic to enable the user to receive alerts when an e-mail from a specific person or regarding a specific topic, arrives at his multimedia server .
- the proxy server is invoked as soon as the phone rings, before the call is transferred to the multimedia server.
- the system and method of the present invention provide a means to convert different types of media into IM messages (and IM messages to multimedia communication) based on presence detection and a set of pre-defined rules that govern the behavior of intercepting incoming media and notifying the recipient. Also, means are provided for utilizing presence information and IM to alert users of incoming calls (ring via IM) and control/direct the flow of incoming calls. Accordingly, the user's availability to different forms of communication while on IM is increased.
- the teachings of the present invention also provide a system and method for accommodating real-time communication between a voicemail system and a calling party, and between the voicemail system and the called party.
- voicemail systems do not communicate anything other than a prerecorded message to either of the calling party, or the called party.
- the voicemail system is communicating real-time (approximately) information to the calling party (e.g., information received from the calling party) , and communicating real-time (approximately) information to the called party (e.g., information received from the calling party) .
