  • Patent number: 8891521
    Abstract: In one embodiment, a reservation proxy monitors for received connectivity check messages or beginning-of-media-flow indication messages. When either type of message is observed, the reservation proxy requests resource allocation for a media flow associated with the received message. The amount of resource allocation requested may be coordinated by exchanging messages with a call controller or policy server for one of the endpoints of the media flow, or the amount of resource allocation may be identified within the received message.
    Type: Grant

  • Publication number: 20070201449
    Abstract: A method for providing communication protocol interoperability may include receiving a request from a first endpoint to establish a communication session with a second endpoint, the request uses a first communication protocol. The method also includes receiving a first response from the second endpoint, the first response uses a second communication protocol different than the first communication protocol. The method may also include initiating a timer for receiving a set of capabilities from the second endpoint and establishing the communication session between the first endpoint and the second endpoint.

  • Publication number: 20070204065
    Abstract: A method for providing communication protocol interoperability includes receiving a first request from a first endpoint for communication with a second endpoint. The first endpoint uses a first type of request of a first protocol, and the second endpoint uses a second type of request of a second protocol. The first type of request and first protocol are different than the second type of request and the second protocol. The method also includes retrieving a selected piece of information from a selected element of the first request. The selected element does not match an element of the second type of request. The method also includes generating a second request by mapping the selected piece of information of the first request to a selected element of the second type of request. The method also includes processing and sending the second request to the second endpoint based on the processing of the second request.

  • Publication number: 20070201509
    Abstract: According to an embodiment of the present invention, an apparatus for addressing compatibility in a session protocol environment is provided that includes a communications platform operable to communicate with a first endpoint and a second endpoint and to recognize signaling capabilities of the first and second endpoints. The apparatus also includes a media termination point (MTP) operable to communicate with the endpoints and the communications platform, the media termination point being provisioned by the communications platform in a stream that involves the first and second endpoints if a signaling compatibility issue is present amongst the endpoints. If an out-of-band digit from the first endpoint is received by the communications platform, the out-of-band digit is sent to the MTP, which is operable to inject a digit associated with the second protocol into the communication session such that a mapping occurs between the digits for the first and second protocols.

  • Publication number: 20070201367
    Abstract: A system and method are provided for controlling a transfer rate between a first endpoint and a second endpoint, wherein the first endpoint implements a first protocol and the second endpoint implements a second protocol. The system and method may comprise elements for receiving a first control message from the first endpoint, wherein the first control message conforms to the first protocol and comprises instructions for adjusting the transfer rate to a designated bandwidth; generating a second control message that conforms to the second protocol and comprises instructions for adjusting the transfer rate to the designated bandwidth; and sending the second control message to the second endpoint.

  • Publication number: 20060268824
    Abstract: A communication system includes a call agent that coordinates and supervises communications between endpoints. The call agent allocates a QoS agent for each endpoint involved in a call. The QoS agents generate reservations for the call in order to provide the call with a guaranteed amount of bandwidth and an established QoS. Each endpoint or location associated with an endpoint has a reservation policy that determines how calls are to be handled when a reservation is or is not obtained and when a reservation is lost or obtained during a call. The communication system is able to handle reservations, or the lack thereof, during various situations like on hold, call transfer, call forwarding, conference call, and shared line services.

  • Publication number: 20060171309
    Abstract: An apparatus for communicating data in a shared line environment is provided that includes a first reservation element operable to communicate with a second reservation element. The first reservation element is associated with a first location and the second reservation element is associated with a second location. A call may be initiated between the first location and the second location, the second location having one or more end-user devices that share a common line. The first reservation element is operable to reserve bandwidth associated with a connection that involves the first location and the second location before the call occurs.
