SNAP-IN INVOCATION FOR CALL RECONSTRUCTION

摘要

During a Session Initiation Protocol dialog setup, a media gateway or container executes or initiates two or more applications that provide features during a conference call. The applications are applied to messages or data in the conference call based on a sequence order established during the setup of the conference call. The sequence order and the application identities are stored in a shared database. When a failure occurs during the conference call, the applications are reestablished in the reconstructed or reestablished conference call. The application reconstruction includes reinitiating the applications with the same sequence as previously established before the failure. As such, the user has the same features applied in the same way before and after the failure, which improves the systems performance and expected operation.

1. A method of managing a Session Initiation Protocol (SIP) dialog between two or more network elements, the method comprising:
determining that a signaling-disrupting event has occurred during a SIP conference call; reestablishing the SIP dialog between the network element and the conference controller; and re-initiating two or more applications executed in a media path, wherein the two or more applications are associated with a sequence order, and wherein the two or more applications are re-initiated with the sequence order.
