ISDN Layer 3 internal error
The ISDN Layer 3 software has detected an internal error. All calls using this Layer 3 process are cleared and the data link layer is deactivated.
If this error occurs frequently it may indicate a problem with Blueworx Voice Response. Disable and re-enable the trunk on which the error occurred and try again. If the problem persists, stop and restart the signalling process using the Custom Server Manager menu option. All other trunks using the signalling process are disabled. If this does not solve the problem shut down and restart Blueworx Voice Response. If none of the above is successful, call Blueworx Support.
