Starting or Stopping Telephony Application Services
Starting or Stopping Telephony Application Services
This procedure explains how to start, stop, pause, restart, or resume Telephony Application Services (TAS) on a specific computer using the Microsoft Management Console (MMC) snap-in for Microsoft Speech Server (MSS).
To start or stop TAS
Open the MMC Administration console. (For instructions, see Administering Speech Server Using MMC.)
In the console tree, double-click Microsoft Speech Server and then double-click the applicable group.
In the details pane, right-click the applicable TAS computer and then do one of the following:
Click Stop to stop the service.
Click Pause to pause the service.
Click Start to start the service.
Click Resume to resume the service after a pause.
Click Restart to restart the service.
Note The service can also be started or stopped using the command line. To start the service from a command prompt, type net start tas or type net start "Telephony Application Services". To stop the service from a command prompt, type net stop tas or type net stop "Telephony Application Services".
Remarks
To ensure that a service is functioning properly, place a test call, then view the Windows Event log (see Analyzing Logged Data).
The use of the net stop command causes a forced shutdown. Any calls (for TAS) or sessions (for SES) currently in progress are dropped immediately with the service stopping almost immediately. To perform a graceful shutdown, use the net pause command, wait for all calls or sessions to complete, then use the net stop command.
The use of the net pause command causes the server to stop accepting new calls but to continue processing existing calls for up to the time value set in the ShutdownTimeout property. Pausing the TAS service using the net pause command may give misleading information. This command expects TAS to pause within 20 seconds and generates a "service failed to pause" error if it does not. This error can be ignored as TAS will pause once all existing calls are complete. Use the Services snap-in in MMC to pause the TAS service because this method correctly reports the current state of the service.
The net continue command causes a paused server to accept calls again.
