How to: Enable and Disable a Speech Server Application

You can enable and disable applications using the Speech Server Administrator console. When an application is added to Speech Server, it is configured to accept calls to specific phone number addresses. When the application is enabled, Speech Server preloads the resources listed in the application manifest file (if specified) and, when a call is received, starts an instance of the application to handle it.

When the application is disabled, Speech Server does not start an instance of the application for new incoming calls. However, calls that are in progress when the application is disabled are completed.

You should disable an application to temporarily take it out of service for the following reasons:

  • You plan for the application's resources to be unavailable, such as during application updates and server maintenance.
  • An unplanned event occurs, such as after a sudden hardware failure.

Prior to disabling an application, redirect calls to a suitable alternative application, such as the same application deployed on the same or another computer running Speech Server or an application specifically designed to handle calls for out-of-service applications. This might require reconfiguration at the SIP peer or the DNS server that is sending calls to Speech Server so that calls get directed elsewhere. Failure to do so can result in an increased number of rejected calls.

Note

If an application is not enabled for an incoming call, the call is declined.
