Signalling interface: unknown cause received from device driver
The Blueworx Voice Response signalling interface detected an unknown cause in an event received from the device driver. This is caused by an error in the Cause field of the SL_CALL_ABORT_REQ primitive. (The Cause field indicates the reason why an active call is being cleared.) The signalling interface is continuing.
If you are not using common channel signalling or a signalling process, this error should not occur. If you are using common channel signalling or a signalling process, frequent occurrence of this error indicates a problem in Blueworx Voice Response. Shut down and restart Blueworx Voice Response. If the problem persists, contact Blueworx Support.
