Telephone channel is hung

When a telephone channel remains in an off-hook state after the caller has hung up, check the following:

Does the voice application state table terminate with a CloseEverything or TerminateCall action?

Voice applications require a state to indicate that the channel is no longer in use. CloseEverything releases all resources allocated to the application, including hanging up the telephone line and closing host sessions. TerminateCall does not terminate state table processing, but it does disconnect the current caller. Ensure that the state table uses one of these actions to hang up the phone line.

For information about CloseEverything and TerminateCall, see Blueworx Voice Response for AIX: Application Development using State Tables.

Have you stopped and restarted the channel?

Sometimes stopping and restarting the channel can resolve temporary problems. Use the information provided in Blueworx Voice Response for AIX: Configuring the System to disable the channel then activate it again.

Are you using a signaling process that you developed yourself?

Have you configured Blueworx Voice Response to use your signaling process? (See Blueworx Voice Response for AIX: Configuring the System for more information.)

Check that your signaling process is still running. Message 32011 in the error log indicates that a signaling process has terminated.

The usual cause of this problem is that your signaling process has not cleared a call correctly. Message 32012 in the error log indicates that your signaling process has ignored an SL_CALL_ABORT_REQ primitive. This is an error in your signaling process. See the explanation of message 32012 in Blueworx Voice Response messages identified by number and the description of the SL_CALL_ABORT_REQ primitive in Blueworx Voice Response for AIX: Programming for the Signaling Interface.

Use signaling interface tracing to see the primitive sent to your signaling process by Blueworx Voice Response. For information on tracing signaling interfaces, see Blueworx Voice Response for AIX: Programming for the Signaling Interface.
