  • Phone number and name of the person or business you are calling
  • Announcement for the STS operator to make at the start of your call (e.g., “This is John calling to check on my dog.”)
  • Instructions for the STS operator (e.g. details about the subject of the call, menu option, or anything to make the call easier)
