Auto Complete Rule for Phone Numbers

Summary: Auto Complete Rule for Phone Numbers

Content (please ensure you mask any confidential information):

Hi all, as per business requirement, the phone number field in contact info should be restricted to only 10 digits. Also, no special characters or alpha numeric values should be allowed.

This rule should apply to anybody who enters phone, whether employees themselves from ESS or admin/HR on behalf of employees.

Would appreciate if someone could guide on how to write both conditions in one rule. Please share screenshots of the rule written if someone already has the achieved the requirement.

This is urgent.
