ISDN trunk state machine invalid primitive
The ISDN signalling process trunk state machine received an unexpected primitive. This means that the primitive could not be identified or that the primitive was not expected in the current state of the trunk.
If this error occurs frequently it may indicate a problem with Blueworx Voice Response. Stop and restart the signalling process using the Custom Server Manager menu option. If this does not work, shut down and restart Blueworx Voice Response. If none of the above is successful call Blueworx Support.
