Patent number: 8547967Abstract: A method for rerouting IP (Internet Protocol) telephony call information includes, during an active IP telephony call made by a first IP telephony phone for originating IP telephony calls over an IP network, with a boundary element, actively detecting a network failure condition in the IP network which indicates a switchover to a PSTN (Public Switched Telephone Network) network and generating a failure notification; and with a server for receiving the failure notification, generating a dynamic switchover instruction generated that is sent to the first IP telephony phone, the dynamic switchover instruction initiating automatic switchover of the active IP telephony call to a PSTN network. A method for rerouting IP (Internet Protocol) telephony call information includes, with a server, monitoring an IP network for route failures; and with the server, generating a switchover instruction when an active IP telephony call is interrupted by a route failure.Type: GrantFiled: June 21, 2011Date of Patent: October 1, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: David A. Grabelsky, Michael Homeier

Patent number: 8539552Abstract: A system and method for network based policy enforcement of intelligent-client features is provided. An operator of an IP telephony and/or IP multimedia network may enforce authorization or privileges of intelligent end-user clients to utilize or invoke services in the network. A network policy enforcement point is maintained in the network by elements that are under control of the network operator. The network policy enforcement point controls access to, and invocation of, features and services that may otherwise be delivered to subscribers without the knowledge or authorization of the network. The network policy enforcement point receives messages, associates the message with a known service, makes a determination as to whether a beneficiary of the service is authorized to invoke the service, and then filters the messages based on the determination.Type: GrantFiled: September 25, 2003Date of Patent: September 17, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: David Grabelsky, Anoop Tripathi, Michael Homeier, Guanglu Wang

Patent number: 7564835Abstract: A system and method for maximizing the use of bandwidth optimization techniques in a voice-over-packet telephony system. In exemplary embodiments, the VOP system includes a plurality of telephones connected to a VOP telephony system. Upon receiving request to initiate a VOP connection, the end office switch connects to an originating softswitch for signaling functions and to an originating media gateway for transporting the media associated with the VOP connection. A connection information system accessible to the softswitch maintains connection information relating to media sessions between the originating media gateway and a plurality of candidate terminating media gateways. The connection information system may be accessed during connection initiation and advantageously used to determine whether there are nearly-simultaneously occurring and distinct media sessions having common endpoints such that bandwidth optimization techniques may be implemented.Type: GrantFiled: November 6, 2002Date of Patent: July 21, 2009Assignee: 3Com CorporationInventors: David Grabelsky, Anoop Tripathi, Boris Bekkerman, Michael Homeier

Patent number: 7480723Abstract: A method and system for providing directory based services is provided. The directory service may process an ambiguous destination identifier from a call-session request to multiple database entries in a directory server, and return an appropriately constructed response that can be interpreted by a user as a prompt for additional input to refine the destination identifier. The possible matches could be sent as a list of possible choices. The user can then select the desired match from the list and send a follow-on request including the selection to the directory server. Based on the selection, the directory server will then either send additional possible matches to the user or obtain a contact address corresponding to the selection. After resolving the ambiguous match to a unique destination identifier, a call can then be established.Type: GrantFiled: April 8, 2003Date of Patent: January 20, 2009Assignee: 3Com CorporationInventors: David Grabelsky, Anoop Tripathi, Michael Homeier, Sudhakar Ramakrishna

Patent number: 7463620Abstract: Systems and methods for controlling features and services in packet-based networks are disclosed. The present application provides systems and methods that include sending a first message to a network core device, and identifying a profile from user account information stored on the network core device. The profile specifies which features and services may or may not be implemented by an end device. In the systems and methods of the present application, the profile is added to a second message that is sent from the network core device to the end device. Alternatively, a single message or multiple messages containing the profile, regardless and/or independent of any prior message sent from an end device, may be sent from the network core device to the end device. These systems and methods may also use the session initiation protocol for their communications, with the end devices being session initiation protocol phones and the network core device being a session initiation server.Type: GrantFiled: September 10, 2002Date of Patent: December 9, 2008Assignee: 3Com CorporationInventors: Guanglu Wang, Michael Homeier, Anoop Tripathi

Patent number: 6785374Abstract: Transaction Capabilities Application Part (TCAP) information from an Signaling System 7 (SS7) network (11) is provided, in response to an original SIP-compatible request by an SIP entity (17) in an SIP network (10), to the SIP network where the TCAP information is then used to facilitate call setup and routing of the call. In one embodiment, the SIP network locally stores the TCAP information upon receipt (at least temporarily) such that the TCAP information is available for subsequent local use without requiring a correspond inquiry to the SS7 network.Type: GrantFiled: September 30, 2002Date of Patent: August 31, 2004Inventors: Guanglu Wang, Michael Homeier, Anoop Tripathi, David Grabelsky
