 """Format a number using the original format that the number was parsed from. The original format is embedded in the country_code_source field of the PhoneNumber object passed in. If such information is missing, the number will be formatted into the NATIONAL format by default. When we don't have a formatting pattern for the number, the method returns the raw input when it is available. Note this method guarantees no digit will be inserted, removed or modified as a result of formatting. Arguments: number -- The phone number that needs to be formatted in its original number format region_calling_from -- The region whose IDD needs to be prefixed if the original number has one. Returns the formatted phone number in its original number format. """
