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.
