.normalize_number(number, options = {}) ⇒ Object

This method requires a country_code attribute (eg. NL) and phone_number to be set. Options:

:country_number => The country dial code (eg. 31 for NL).
:default_country_number => Fallback country code.
:country_code => The country code we should use.
:default_country_code => Some fallback code (eg. 'NL') that can be used as default (comes from phony_normalize_numbers method).
:add_plus => Add a '+' in front so we know the country code is added. (default: true)

This idea came from:

.plausible_number?(number, options = {}) ⇒ Boolean

Wrapper for Phony.plausible?. Takes the same options as #normalize_number. NB: This method calls #normalize_number and passes options directly to that method.

Returns:

  • (Boolean)
