Title: Method and system for exchanging and storing telephone messages

Description:
FIELD AND BACKGROUND OF THE INVENTION  
       [0001] Voice mail supplied by PTT&#39;s (Postal, Telegraph and Telephone) and cellular carriers is generally stored in voice boxes. The popularity of these systems has grown dramatically with the great penetration of cellular telephone since the traditional home answering machine cannot work while the telephone is shut down. The technology used by the producers of the voice boxes for the telephone carriers, such as Comverse Technology, Inc., (Woodbury, Long Island, N.Y. USA), Brooktrout Technology Inc., (410 First Avenue, Needham, Mass. 02494-2722), etc., is based on a server containing a storage media, typically hard disks, in which each box owner has a specific location or address in which his/her messages are stored. While a new message (voice or fax) is stored, a notification to the telephone owner is given through the carrier switch either by a specific tone, which is heard when using the phone or, alternatively in cellular phones by sending a message using SMS (Small Message Standard) technology.  
       [0002] The main disadvantages of existing systems are;  
       [0003] 1) To send a message so that it reaches the box in a short time is expensive and requires rather sophisticated switching; and  
       [0004] 2) In order to retrieve a message, the caller has to communicate directly with his/her box, which may be involved in a long distance call national or international call if the owner is outside his local area or out of the country.  
       SUMMARY OF THE INVENTION  
       [0005] The present invention provides a method and apparatus for sending voice and facsimile messages via the Internet.

     DESCRIPTION OF THE PRESENT INVENTION  
     [0025] Reference is now made to FIGS. 1 and 2. FIG. 1 is a schematic illustration of the system and method for sending a voice and/or facsimile message, constructed and operative in accordance with a preferred embodiment of the present invention.  
     [0026] According to an embodiment of the present invention, the method is based on utilizing a plurality of servers, generally designated  20  and  40 , which can exchange files. More specifically the servers exchange and store files using e-mail protocol with attached files.  
     [0027] Software for distributing and receiving files is commercially available, for example, “Exchange Server” by Microsoft Inc., (One Microsoft Way, Redmond, Wash. 98052-6339). Each server also contains a CTI (Computer Telephony Integration) card  22 , which accepts the calls and converts the voice data into digital files, which can be stored and handled by computers in a regular say. An example of a CTI card which can be used with analogue systems is the “Dialogic card” No. VFX/40 ESC+, available from Dialogic 1515 Route Ten, Parsippany, N.J. 07054 USA. CTI cards convert analogous voice data into digital data. These cards usually have the caller ID function which can detect and register the telephone number from which the call was made.  
     [0028] In digital telephony, where VoIP (Voice over Internet Protocol) are used, CTI cards are not required, since the digital data is prepared in the handset itself.  
     [0029] The servers  20 ,  40  also contains a database  24 , such as “SQL” by Microsoft Inc. or “Oracle” by Sun Microsystems, Inc. (901 San Antonio Road, Palo Alto, Calif. 94303 USA).  
     [0030] In addition, servers  20 ,  40  contains at least one software application, generally designated  26 , that enable the caller to leave and retrieve messages. The server also includes an e-mail server  28 , such as “Exchange” by Microsoft Inc. or any other suitable server. Preferably the e-mail server  28  should be capable of sending SMS textual messages to cellular telephones (which have been configured for SMS). SMS message servers  30  are available through several vendors, such as UNIMOBILE.COM, GOSMS.COM, IBM for example.  
     [0031] Reference is now made to FIG. 2 which is a flow chart illustration of the method for sending the message.  
     [0032] A caller S who wishes to leave a message, calls a focal server  20  (step  202 ), where the call is directed to the CTI card through the software application A (step  204 ) The CTI card extracts the ID (identification details) of the caller S (step  206 ).  
     [0033] The caller S is then requested to enter the destination telephone number, including area code and country code (if applicable) (step  208 ) for the message, after which the caller S is prompted the to record his voice message (step  210 ). If a fax is being sent, the caller is prompted to send his fax message (as will be described below).  
     [0034] The recorded voice message is then compressed as a standard compressed wave file (step  212 ).  
     [0035] The recorded message, along with the telephone number of the sender S, is preferably sent by e-mail server  28  through the Internet to the service server  40  located in the local area of the addressee R (step  214 ). “The local area” means the location in which the telephonic rate between the addressee and the server is the lowest.  
     [0036] The e-mail server  28  receives and sends e-mail and acts as an exchange server.  
     [0037] The message along with the telephone numbers of the sender S and the addressee R is stored in the database of server  40  (step  216 ). An SMS notification is sent by the software application located in server  40  to the telephone of the addressee R (step  218 ), to advise him that a voice/fax message has been received from S, and that it can be retrieved by dialing a dedicated telephone number associated with the server  40 .  
     [0038] Reference is now made to FIG. 3, which is a flow chart illustration of the method of retrieving a voice message.  
     [0039] If the addressee R wishes to hear the voice message, he calls the dedicated telephone number associated with server  40  (step  252 ).  
     [0040] The call is directed to the CTI card through the software application B associated with retrieval of messages (step  254 ) The CTI card extracts the ID (identification details) of the caller S (step  256 ).  
     [0041] Software B can be reached by either allocating different lines to Software A and Software B, or by asking the caller if he wishes to send a message (in which case the caller is directed to Software A, as described above) or to retrieve a message.  
     [0042] Once the caller (retriever R) is identified through the caller ID, the messaged is extracted from the database and read for him (step  258 ).  
     [0043] At the end of the message, the retriever R has the option of replying (query box  260 ). If the retriever R wishes to record a reply message, the message is recorded (step  262 ) and forwarded to server  20  (originating the initial message) (step  264 ). Software A at server  20  then sends SMS notification to the sender S (step  266 ) (as described above—step  218 ).  
     [0044] Sending a facsimile (Fax), which is illustrated with reference to FIG. 4, is similar to sending a voice message, described hereinabove with respect to FIG. 2, and similar reference numbers have been used for similar steps.  
     [0045] A caller S who wishes to leave a message, calls a local server  20  (step  202 ), where the call is directed to the CTI card through the software application A (step  204 ) The CTI card extracts the ID (identification details) of the caller S (step  206 ).  
     [0046] The caller S is then requested to enter the destination telephone number, including area code and country code (if applicable) (step  208 ) for the message, after which the caller S is prompted the to send the fax message (step  226 ).  
     [0047] The CTI card  22  converts the message to a TIF (Tagged Image File) file (step  228 ) instead of a compressed wave file (step  212 ).  
     [0048] The TIF file is then opened and the first page (or other page) having the addressee&#39;s facsimile number is accessed (step  230 ). Any random noise is filtered and the blank area of the first page ‘removed’ (step  232 ). An OCR (Optical Character Recognition) engine (not shown) is used to recognize the recipient fax number.  
     [0049] The Software A prepares an email message with an attached TIF file (step  234 ) and sends the message via the Internet to the service server  40  located in the local area of the addressee R (step  236  (similar to  214 ).  
     [0050] Reference is now made to FIG. 5, which is a flow chart illustration of the method of retrieving a fax message.  
     [0051] The recipient RF of the SMS notification that a fax has arrived, calls the server  40  from a fax machine using the telephone mode (step  282 ). The recipient RF is requested to dial the telephone number, to which the SMS was sent (step  284 ).  
     [0052] The call is directed to the CTI card through the software application B associated with retrieval of messages (step  286 ) The CTI card transmits the fax message to the fax machine of RF (step  288 ).  
     [0053] Thus, in contrast to the prior art, the present invention enables a person to leave a message for another person irrespective of the telephone carrier and without the necessity of using voice mail boxes.  
     [0054] In a further embodiment of the invention, the servers  20 ,  40  may be the “T-Mailer” servers, available from the Assignees of the present invention (Varicom Communications Ltd.). The T-Mailer service enables people to enter the database via the Internet and add their telephone number together with their e-mail addresses and their manes. Thus, the server can also send a copy of the message to the member&#39;s e-mail and give the sender&#39;s name in the SMS notification.  
     [0055] The T-Mailer server is similar to the proxy server described in PCT Patent Application: PCT/IL99/00516 assigned to the Assignees of the present invention. The T-mailer server generally comprises a Computer Telephone Integration (CTI) card connected to a wave API (Application Program Interface) and a message storage device. The server further comprises components such as a voice proxy telephone server and a transport provider for receiving and forwarding voice/text messages.  
     [0056] In another embodiment of the invitation, the call may be forwarded from the telephone of the retriever R when the line is busy or not answering to the nearest server.  
     [0057] Servers  20 ,  40  can be placed all over the world and enable one to send e-mail through out the world at the price of a local call.  
     [0058] It will be further appreciated that the present invention is not limited by what has been described hereinabove and that numerous modifications, all of which fall within the scope of the present invention, exist. Rather the scope of the invention is defined by the claims which follow:
