ISDN signalling process call state machine error
An unexpected error occurred in the ISDN signalling process call state machine. Detailed information of the error is logged. If a call is in progress on the channel on which the error occurred the signalling process attempts to terminate it.
Check the error log for other errors in the ISDN signalling process, which may identify the origin of the error. If this error occurs frequently it may indicate a problem with Blueworx Voice Response. Disable and re-enable the channel on which the error occurred and try again. If this does not work, disable and re-enable the trunk to which the channel belongs. If the problem still persists, shut down and restart Blueworx Voice Response. If none of the above is successful call Blueworx Support.
