  • Patent number: 7916645
    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.

  • Patent number: 7733872
    Abstract: A system and method for implementing a Quality of Service (QoS) fallback using Resource Reservation Protocol (RSVP) includes initiating a communication session with a QoS precondition between a first domain and a second domain. It is determined whether the second domain supports the QoS precondition. Intra-domain RSVP is established in the first domain if the second domain does not support the QoS precondition.

  • Patent number: 7573887
    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.
