  • Patent number: 9054922
    Abstract: In one embodiment, an endpoint elicits a pattern of STUN responses to identify security devices located on a call path. The endpoint then uses address information from the identified security devices to establish an efficient media flow with a remote endpoint. The endpoint can optimize the number of network devices and network paths that process the endpoint's keepalive message. Additionally, the endpoint may request custom inactivity timeouts with each of the identified security devices for reducing bandwidth consumed by keepalive traffic.

  • Patent number: 8005098
    Abstract: Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with load balancing across multiple network address translation (NAT) instances and/or processors. N network address translation (NAT) processors and/or instances are each assigned a portion of the source address traffic in order to load balance the network address translation among them. Additionally, the address space of translated addresses is partitioned and uniquely assigned to the NAT processors and/or instances such that the identification of the assigned NAT processor and/or instance associated with a received translated address can be readily determined there from, and then used to network address translate that received packet.

  • Patent number: 7908480
    Abstract: Authenticating an endpoint using a STUN server includes facilitating a communication session between a first endpoint and a second endpoint over a network. A challenge request is sent to the second endpoint. The challenge request attempts to authenticate the second endpoint and includes an identification. The identification is associated with an expected response identification. A response to the challenge request is received from the second endpoint. The response has an actual response identification. The received response is verified to establish whether the second endpoint is legitimate. The second endpoint is legitimate if the actual response identification includes the expected response identification.

  • Patent number: 7894597
    Abstract: The present invention provides a mechanism for categorizing telephone calls and for providing special information about calls that appear on call lists maintained in a telephone. The invention provides for both providing an indication and for providing an action. When an entry on a call list is highlighted (in a conventional manner), pressing one key adds a flag to the entry on the call list to indicate that follow up action is required. Pressing a second key initiates an action such as attaching a reminder so that the user will be reminded to take action later. Pressing a third key will provide a text message balloon indicating information about the call. The flags and text messages can be added by either the called party or the calling party.

  • Patent number: 7733769
    Abstract: Nodes in an Internet Protocol (IP) network receive probe packets configured to travel over particular IP media paths. The probe packets cause the network nodes to send media path reports to a logging system. The media path reports contain information identifying the different nodes in the media path. The logging system can reconstruct the network topology of a particular media path from the media path reports which can then be used for debugging purposes. In one embodiment the probe packets are Resource Reservation Setup Protocol (RSVP) packets configured for media path probing.

  • Patent number: 7724887
    Abstract: Techniques for using call history for voice data over a packet-switched network includes receiving call history data that indicates a redirected network identity that served as a target of a particular voice data session from a particular calling party. The redirected network identity is different from both a caller network identity that identifies the particular calling party, and a current target network identity that identifies a current target party of the particular voice data session. A call history display composition is formed that indicates at least that the redirected network identity exists. The call history display composition is presented for viewing by at least one of the particular calling party and the current target party. These technique allow a party to redirected communications to easily call or save the network address of a former target of the call.

  • Patent number: 7680065
    Abstract: A system and method allowing control of VoIP communications by configuring a Network Address Translator (NAT) is provided. In a first NAT configuration, such a port-restricted NAT, peer-to-peer Voice over Internet Protocol (VoIP) communications are permitted between a VoIP originator and a receiver. In a second NAT configuration, such as a symmetrical NAT, peer-to-peer communications are not possible without further cooperation of the NAT. In this manner, an entity that has control of the NAT, such as an ISP, is able to have a degree of control over traffic using network resources such as bandwidth.
