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.

System and method for implementing RSVP in a communication environment

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.

Method and system for providing communication protocol interoperability

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.
