The CountryCode key specifies the country/region code portion of the phone number, as specified in [OB930E]. This key is optional. This key is ignored if the DEVICE key is set to "Pad", "X25", or "Switch". This key is ignored unless the Type key is set to "1". The value of the key is ignored unless the UseDialingRules key is set to "1". If the key is present, it SHOULD be a string representation of a country/region code.
