This error indicates that the system received a call from a telephone number that is not recognized or not associated with any known user in the SAP system.
  Cause:

  Missing User Mapping: There may be no user account in SAP that corresponds to the incoming telephone number.
  Configuration Issues: There could be issues with the configuration of the telephone integration settings in SAP.
  Data Synchronization Issues: If the user data is not synchronized properly between the telephony system and SAP, it may lead to this error.
  
  Solution:
  
  
  Check User Mapping:

  Update User Data:
  
  If there have been recent changes to user data (like phone numbers), ensure that these changes are reflected in the SAP system.
