Patent number: 6522743Abstract: A system is provided for routing calls. The system includes a plurality of call centers coupled to a public switched telephone network which supports a caller identification feature and a transfer feature. A trunk interface, coupled via a link to the public switched telephone network, receives a call from the public switched telephone network over the link. A database stores customer profile information and call center information. A processor is coupled to the trunk interface and the database. The processor identifies a customer placing the call utilizing the caller identification feature, retrieves from the database customer profile information associated with the identified customer, and selects one of the call centers in response to the customer profile information and the call center information. The processor routes the call to the selected call center, after which the link is released utilizing the transfer feature.Type: GrantFiled: April 26, 1999Date of Patent: February 18, 2003Assignee: e-talk CorporationInventor: Michael D.

Patent number: 6453039Abstract: Apparatus and method for performing a recoverable routing of calls using an automatic call distributor to avoid loss of calls at busy agent terminals. Switching equipment receives incoming calls and issues a routing request to a server. In response, the server returns the address of a quence to receive and hold the calls. Intermediate telephones are “punched into” the queue for receiving the calls from the queue, and the server detects transfer of calls to the intermediate telephones in order to obtain control of the calls. The server performs a consultative transfer of the calls from the intermediate telephones to agent terminals so that, if an agent terminal is busy, the server may transfer the call back to the switching equipment in order for the call to be rerouted.Type: GrantFiled: June 16, 1999Date of Patent: September 17, 2002Assignee: Cisco Systems, Inc.Inventors: Simon Cutting, Raechel Crosby

Patent number: 6442242Abstract: A call processing apparatus incorporates a robust database supporting both autodialing and autoattendant functions. Incoming calls not directed to a specific telephone extension and any call to a dedicated autodialer function are answered and the caller prompted to speak the name of the desired person or department. A speech recognition platform analyzes the spoken name to provide one or more searchable text strings representing the various spellings associated with the spoken name. The database is searched to retrieve corresponding terminal address instructions such as the telephone number or extension of the named party and call routing to the address is initiated. Alternatively, in an autoattendant mode, a subscriber calls a telephone number associated with a specified service such as a hotline and is asked to identify himself by name. The speech recognition platform again provides a corresponding searchable text string used to retrieve subscriber-specific information for handling the call.Type: GrantFiled: June 25, 1999Date of Patent: August 27, 2002Assignee: Verizon Services CorporationInventors: Alexander I. McAllister, Rita Yadav

Patent number: 6430282Abstract: In methods and apparatus for originating a voice call between first and second voice terminals, a voice call request is received at a data service node, the voice call request identifying the first voice terminal. A call origination request is transmitted from the data service node to a telecommunication switch, the call origination request identifying the first and second voice terminals. The telecommunications switch originates one call from the telecommunications switch to the second voice terminal and another call front the telecommunications switch to the first voice terminal. The telecommunications switch then connects the one call to the other call to connect the first voice terminal to the second voice terminal. The methods and apparatus are particularly useful in connection with advertising on the World Wide Web and in connection with international calling services.Type: GrantFiled: May 28, 1996Date of Patent: August 6, 2002Assignee: Nortel Networks LimitedInventors: Cecil H. Bannister, Rangaprasad Govindarajan, Russell A. Edwards

Patent number: 6404885Abstract: A telecommunications method and system for providing and monitoring multiple classes of service to users seeking dial-up access to a given resource. Incoming calls from two user groups, one group subscribing to a first service level and the other group subscribing to a second service level, are initially assigned to open circuits in a first shared dial hunt group. When all circuits are busy, only calls from users subscribing to the second service level are routed to open circuits in a second dedicated dial hunt group so that second level service subscribers will have fewer calls blocked than first level service subscribers. In an alternative implementation, calls from users subscribing to a first service level are routed only to open circuits in a first dial hunt group and calls from users subscribing to a second service level are routed initially to open circuits in a second dial hunt group.Type: GrantFiled: April 30, 1999Date of Patent: June 11, 2002Assignee: AT&T Corp.Inventors: Frank A. Field, Daniel Paul Heyman, R. Craig Hubbard, Yonatan Aharon Levy, Danielle Liu, Jeffrey J. Polhemus, Eberhard F. Wunderlich

Patent number: 6366668Abstract: The alternate destination redirection (ADR) feature (102) of telephone switching systems (101) or an equivalent is used to implement a “post-route” routing architecture having the benefits of a “pre-route” routing architecture in a network ACD (FIG. 1). The ADR feature is administered in the network (100) for individual ACD systems and individual call types at each ACD system to identify another ACD system as an alternative destination for calls of the individual call type rejected by the individual ACD system. The network distributes (302) calls to the plurality of ACD systems (110-112) on a basis (e.g., fixed percentage, round-robin) that does not require the network to know the status of the individual ACD systems. Upon having a call of an individual type routed thereto, an individual ACD system checks (304) the status of the ACD system that is administered as the alternative destination for its rejected calls of the individual type.Type: GrantFiled: March 11, 1999Date of Patent: April 2, 2002Assignee: Avaya Technology Corp.Inventors: Simon C. Borst, Andrew D. Flockhart, Francis C. Hymus, Eugene P. Mathews, Martin I. Reiman, Judith B. Seery, John Z. Taylor

Patent number: 6330323Abstract: A system and method for Enhanced Overflow Call Processing redirects calls which cannot be completed to alternate terminations. An originating switch queries a network database for an alternate termination for the call each time the originating switch detects that the call cannot be completed to the current termination. The network database determines the alternate termination for each query using a hierarchical set of multi-branch overflow statements which are configured by the user. A set of overflow statements is selected by the network database based on the original termination of the call. The set of overflow statements is searched hierarchically until an active overflow statement is found. This overflow statement then controls all queries relating to that call. The reason the call was not completed is used to select either an alternate termination to which the call is to be routed or a particular treatment, such as a busy signal or network message, which is to be applied to the call.Type: GrantFiled: January 11, 1996Date of Patent: December 11, 2001Assignee: MCI Communications CorporationInventors: Louis G. Gottlieb, Cathleen Frazier, Wesley Rogers, Roger P. Engdahl

Patent number: 6327364Abstract: A system and a method for managing incoming calls within a call queue include a network bandwidth monitor for monitoring network bandwidth availability on a call center and a queue call rate monitor for determining a total of all call charge rates associated with the calls. A queue manager determines the order of advancement of the calls within the queue. If the network bandwidth monitor determines that network bandwidth availability is below a predetermined threshold, high network bandwidth calls are preferentially advanced to free up additional network bandwidth. Calls with high charge rates are preferentially advanced if the total call charge rate in the queue exceeds a predetermined maximum threshold. If the maximum total call charge rate threshold is exceeded and the network bandwidth availability level is below the minimum threshold, a relative priority for maintaining network bandwidth availability and reducing total call charge rates will determine the order of call advancement.Type: GrantFiled: December 15, 1998Date of Patent: December 4, 2001Assignee: Siemens Information and Communication Networks, Inc.Inventors: Shmuel Shaffer, William J.
