Patent number: 8160234Abstract: A technique is disclosed that optimizes the background noise experienced by a party who is calling into a call center. Working as part of an overall call-assignment algorithm, the technique considers the acoustic noise that is present in the vicinities of multiple call-center agents who are otherwise satisfactory candidates to handle a call. The technique then selects an agent to handle the call who is associated with an optimal acoustic noise. Typically, the selected agent is associated with lowest background noise level. The background noise is monitored at each call agent's station by evaluating the signals that are present at the agent's microphone. Usually, this is done when a call agent is between calls and, as a result, is not using her headset at that moment. In other words, the background noise is actually measured, and the measurements are then used to assign a call agent to the incoming call.Type: GrantFiled: May 5, 2008Date of Patent: April 17, 2012Assignee: Avaya Inc.Inventor: Eric John Diethorn

The IMS network comprises a subscriber server adapted to store a new phone number including a new area code for a subscriber assigned as a result of the split numbering plan area code. The IMS network further comprises a call control system coupled to the subscriber server adapted to register user equipment of the subscriber assigned the new phone number with the subscriber server. The call control system is further adapted to associate an old phone number of the subscriber used prior to the split numbering plan area code with the new phone number in an implicit registration set. The call control system is further adapted to receive a call for the old phone number and identify the new phone number associated with the old phone number in the implicit registration set and to deliver the call to the user equipment.Type: GrantFiled: October 30, 2006Date of Patent: September 13, 2011Assignee: Alcatel LucentInventors: Suzann Hua, Ahmed N.

Patent number: 8014304Abstract: The present invention relates to a method of decoding tokenized Session Initiated Protocol. A token from a tokenized Session Initiated Protocol packet is received. A decoding table is accessed and the corresponding entry for the token is determined. The token is executed according to the corresponding entry. This may be done for all tokens in a tokenized Session Initiated Packet. Once the tokens have been executed according to their entries in a decoding table, the decoded tokenized Session Initiated Protocol packet is provided.Type: GrantFiled: October 6, 2009Date of Patent: September 6, 2011Assignee: Sprint Communications Company L.P.Inventor: Joel Mark Studtmann

Patent number: 8000318Abstract: A system and method that establishes a phone call over a packet network. The process may include receiving a call request from an originating call device on a packet network to call a terminating call device. A first transmission path may be determined between the originating and terminating call devices. Status of a terminating segment at a first terminating trunk may be determined and, if the status of the terminating segment at the first terminating trunk is within a first range, a call between the originating and terminating call device may be established via the first terminating call trunk. Otherwise, if the status of the terminating segment at the first terminating trunk is within a second range, a second transmission path via a second terminating trunk between the originating and terminating call devices may be made.Type: GrantFiled: May 31, 2007Date of Patent: August 16, 2011Assignee: Embarq Holdings Company, LLCInventors: William L. Wiley, Michael K. Bugenhagen, Robert J. Morrill

Patent number: 8000464Abstract: When a call offer is received by a telecommunications peering network destined for a telephone number maintained within a peering database, the telecommunications peering network attempts to route the call directly to the peering partner telecommunications (e.g., broadband, voice over internet protocol, etc.) equipment. If the route fails with a corresponding destination unreachable failure code, the telecommunications peering network can attempt to determine whether or not the telephone number has been ported to a different provider. If the telecommunications peering network determines that the telephone number has been ported, the telecommunications peering network removes the telephone number from the peering database.Type: GrantFiled: March 23, 2010Date of Patent: August 16, 2011Assignee: IntelePeer Inc.Inventor: John Ward

Patent number: 7995737Abstract: Independent telephony systems are integrated by using symmetric forking from both systems. Calls received by either system are forked to the other system. Thus, a call can be accepted by one of the systems, using its external interfaces, and presented to all devices in both systems. Each system is enabled to leverage internal call control advanced features to enhance overall user experience. Internally inserted parameters to call requests are used between the two systems for preventing endless loop of calls between the integrated systems.Type: GrantFiled: November 5, 2007Date of Patent: August 9, 2011Assignee: Microsoft CorporationInventors: Danny Levin, Mahendra D. Sekaran, Bimal K. Mehta, Li Shen, Vadim Eydelman, Russell P. Bennett, Paul D. Tidwell, Rajesh Ramanathan, Gurdeep Singh Pall

Patent number: RE43361Abstract: The present invention is a telecommunications system having separate switch fabric and switch intelligence. The system comprises a switch fabric, a switch intelligence, and a feature processor. The switch intelligence is logically separated from the switch fabric and comprises a switch fabric proxy, a facility service, a connection manager service, and a call segment instance service. The switch fabric proxy is coupled to the switch fabric via a vendor-specific first Application Programming Interface (API). The switch fabric proxy supports a second API, which is common across all vendors, representing functions supported by the switch fabric. A facility instance, which is instantiated by a facility service using a facility model, represents the bearer and signaling facilities of a party to a call, and interacts with the switch fabric proxy via the second API to communicate with the switch fabric.Type: GrantFiled: January 24, 2002Date of Patent: May 8, 2012Assignee: MCI Communications CorporationInventors: Douglas R. Cardy, Ken Rambo, Carol Waller
