Returns EXACT_MATCH if the country_code, NSN, presence of a leading zero for Italian numbers and any extension present are the same. Returns NSN_MATCH if either or both has no region specified, and the NSNs and extensions are the same. Returns SHORT_NSN_MATCH if either or both has no region specified, or the region specified is the same, and one NSN could be a shorter version of the other number. This includes the case where one has an extension specified, and the other does not. Returns NO_MATCH otherwise. For example, the numbers +1 345 657 1234 and 657 1234 are a SHORT_NSN_MATCH. The numbers +1 345 657 1234 and 345 657 are a NO_MATCH.
