What is adDSUIQDBUPhoneNumber3?

This parameter stores the third phone number available for dial backup, which the system attempts after the first two numbers have failed. Network engineers use this to add another layer of redundancy, ensuring multiple opportunities to establish backup connectivity. A value of '5555551212' means after the first two dial attempts are unsuccessful, the system will try this third phone number.
