CALLBACK METHOD
FIELD OF THE INVF-NTION The present invention relates to computer network-based telephony in general, and more particularly to callback methods and apparatus therefor.
BACKGROUND OF THE INVENTION Computer network-based telephony systems are well known in the art. One such system is Applicant assignee's Surf&Call™ system, commercially available from VocalTec Communications Ltd., Herzliya, Israel, which provides real-time voice communications via Internet Protocol (IP) computer networks. In the Surf&Call™ system a computer user uses a Hypertext Markup Language (HTML) browser to download from the Internet a Surf&Call™- enabled HTML document ("web page") which contains a selectable hypertext link, such as a button, that may be used to initiate the Surf&Call™ service. Should the user wish to speak to an agent regarding the web page, the user may select the link, which causes software installed at the user's computer to request a voice communications session between the user's computer and a telephone-based agent via an IP network-to-Public Switched Telephone Network (PSTN) or IP network gateway-to-Private Branch Exchange (PBX). Surf&Call™ may be used with Automatic Call Distribution (ACD) call centers, in which case the user's call may be directed to an available agent. Another such system is Applicant assignee's Surf&Chat™ system which provides similar functionality as the Surf&Call™ system for data communications session between the user's computer and a computer-based agent. Unfortunately, when a computer user attempts to initiate a voice or data call to a telephone and/or computer user via a computer network, if the telephone user's line is busy, or if an agent is unavailable, then the computer user currently has no recourse other than to try again at a later time.

An optional ACD server 22 is shown in communication with callback server 20 and telephone user 16, which communication may be effected via computer network 12, via another network (not shown), or directly between ACD server 22 and callback server 20 and between ACD server 22 and telephone user 16.
Reference is now made to Fig. 2 which is a simplified flowchart illustration of an exemplary method of operation of the system of Fig. 1, operative in accordance with a preferred embodiment of the present invention. In the method of Fig. 2, user 10 transmits a callback request to callback server 20 (step 200). The callback request may be made subsequent to unsuccessfully establishing a communications link with telephone user 16 or for any other reason. The callback request may be made using any conventional technique, such as via an HTML form, and preferably indicates to callback server 20 an identifier uniquely identifying user 10, and a telephone number of telephone user 16, a telephone number of a call center where telephone user 16 is located, or other identification that may be used to determine such telephone numbers. The callback request may also indicate a time at or after the callback is to be made, or a time period during which the callback is to be made. At the time designated by the callback request, or, where no such time is designated, at a predetermined time, callback server 20 may optionally deteπnine whether computer user 10 is available for computer-to- telephone communications (step 210) and/or whether telephone user 16 is available for telephone-to-computer communications (step 220). This may be done by deterrnining whether the user's browser is open and/or whether the user is connected to computer network 12. If one or both of users 10 and 16 are available, or irrespective of whether either of the users are available, callback server 20 transmits instructions to computer 14 via computer network 12 to initiate a communications link with telephone user 16 via gateway 18 (step 230). Callback server 20 may provide computer 14 with a telephone number for contacting telephone user 16. Computer 14 then automatically initiates a communications link with telephone user 16 via gateway 18 using conventional techniques (step 240).
Reference is now made to Fig. 3 which is a simplified flowchart illustration of an exemplary method of operation of the system of Fig. 1, operative in accordance with a preferred embodiment of the present invention. In the method of Fig. 3, user 10 transmits a callback request to callback server 20 (step 300). At the time designated by the callback request, or, where no such time is designated, at a predetermined time, callback server 20 requests an available agent from ACD server 22 (step 310) and determines whether computer user 10 is available for network-to-telephone communications (step 320). If both computer user 10 and an agent, represented by telephone user 16, are available, callback server 20 transmits instructions to computer 14 via computer network 12 to initiate a communications link with telephone user 16 via gateway 18 (step 330). Callback server 20 may provide computer 14 with a telephone number for contacting telephone user 16 directly, or else gateway 18 may use conventional Computer Telephony Integration (CTI) techniques for establishing a communications link between computer 14 and telephone user 16 as provided by ACD server 22. Computer 14 then initiates a communications link with telephone user 16 via gateway 18 using conventional techniques (step 340).
Reference is now made to Fig. 4 which is a simplified conceptual illustration of a computer network-based telephony callback system adapted for use with the Surf&Call™ system, constructed and operative in accordance with a preferred embodiment of the present invention. In the system of Fig. 4 a computer user 30 is shown in communication with a computer network 32, such as the Internet, via a computer 34, Computer 34 is preferably configured for voice communications in accordance with conventional techniques, cluding a microphone and other computer network-based telephony software and/or hardware as necessary (not shown). User 30 may thus establish a voice connection to a telephone user 36 at a telephone 37 via a gatekeeper 46 and a gateway 38 connected to computer network 32. Additionally or alternatively, computer 30 is configured for real-time text-based or graphical communications with a computer 44 via a data collaboration (DC) server 48 connected to computer network 32, or with any text-based Internet chat software and/or hardware. User 30 may thus establish a data connection to a computer 44 via computer network 32. A callback server 40 is likewise connected to computer network 32 for comnaunicating with user 30 at computer 34 and, preferably, with telephone user 36 via gateway 38 and/or computer 44 via computer network 32, An optional ACD server 42 is shown in communication with callback server 40 and telephone user 36, which communication may be effected via computer network 32, via another network (not shown), or directly between ACD server 42 and callback server 40 and between ACD server 42 and telephone user 36.
Reference is now made to Fig. 5 which is a simplified flowchart illustration of an exemplary method of operation of the system of Fig. 4, operative in accordance with a preferred embodiment of the present invention. In the method of Fig. 5, user 30 uses browser software on computer 34 to download a Surf&Call™-enabled web page from a web server (not shown) connected to computer network 32 and view the web page (step 500). The web page preferably contains a selectable hypertext link, such as a button, that may be used to initiate the Surf&Call™ service. Surf&Call™ software is then downloaded to computer 34 and is manually or automatically installed, typically as a browser plug-in software module (step 510). The Surf&Call™ software, which typically mcludes a signaling interface, then preferably opens a communication connection from computer 34 to DC server 48 and/or to callback server 40 (step 520) by sending its unique identifier. User 30 then selects the Surf&Call hypertext link, causing the Surf&Call software to send the Universal Resource Locator (URL) of the downloaded web page as well as a Surf&Call ID associated with the web page to gatekeeper 46 (step 530). Gatekeeper 46 then verifies the URL and the ID against an authorization database and retrieves an associated telephone number (step 540). Gatekeeper 46 then sends the telephone number, preferably encrypted, and the network address of gateway 38 to computer 34 (step 550). Computer 34 then sends the telephone number to gateway 38 (step 560) which then attempts to establish a connection to telephone user 36 (step 570).
Computer user 30 may additionally or alternatively establish a data collaboration session with user 36 at computer 44 by sending a request to DC server 48, also typically via hypertext link selection (step 580). At this point, DC server 48 ascertains from the ACD server 42 via CTT link or via any other conventional link, the destination of the data session, such as a network address of computer 44, and connects computer user 34 with agent computer 44 (step 590). Computers 34 and 46 then may synchronize web page retrievals, inputs, and interactions via transmissions to and from DC server 48 (step 600).
Should telephone user 36 be unavailable for a voice and/or data collaboration session with user 30, or should user 30 desire for any reason to communicate with user 36 at a later time, user 30 may use computer 34 to transmit a callback request to callback server 40 (Fig. 2, step 200). The callback request may be made subsequent to unsuccessfully establishing a communications link with telephone user 36 or for any other reason. The callback request may be made using any conventional technique, such as via an HTML form, and preferably indicates to callback server 40 an identifier uniquely identifying user 30, and a telephone number of telephone user 36, a telephone number of a call center where telephone user 36 is located, or other identification that may be used to determine such telephone numbers. The callback request may also indicate a time at or after the callback is to be made, or a time period during which the callback is to be made. At the time designated by the callback request, or, where no such time is designated, at a predetermined time, callback server 40 may determine whether computer user 30 is available for computer-to-telephone communications (step 210) and/or whether telephone user 36 is available for telephone-to-computer communications (step 220). If computer user 30 is available, callback server 40 transmits instructions to computer 34 via computer network 32 via the Surf&Call™ software signaling link to initiate a communications link via the Surf&Call™ software with telephone user 36 via gatekeeper 46 and gateway 38 as described hereinabove (step 230). Callback server 40 may provide computer 34 with a telephone number for contacting telephone user 36. Computer 34 then automatically initiates a communications link with telephone user 36 via gateway 38 using conventional techniques (step 240). Agent selection may be performed in a call center environment via ACD server 42 in accordance with the method of Fig. 3 above. A data collaboration session callback may similarly be initiated between computer 34 and computer 44 (Fig. 3, steps 300 - 340).
