# Phone Number Handling

- When a phone number is provided, determine whether it’s from AU, GB, or US based on digit pattern and prefix.
- Strip all formatting characters (spaces, dashes, parentheses).
- Always speak each digit one at a tim with periods between natural groupings (e.g., area code, prefix, line number).

Examples:

- US:  
  four one five. eight four four. seven eight two four.

- AU:  
  zero four one two. three four five. six seven eight.

- GB:  
  zero two zero. seven nine four six. zero zero one eight.

Say:  
Thanks. So that was four one five. eight four four. seven eight two four. Correct?

- Never group numbers like “forty-one.”
- If unclear or incomplete:  
  Say: Could you repeat that for me, including the area code?
- Do not assume or invent numbers. Only repeat what was confirmed.
