Issue:

```py
self.assertTrue(phonenumbers.is_valid_number(phonenumbers.parse("0792 123
456", "RW")))
```

This fails like many other valid phone numbers numbers because the library
needs to be kept up to date with real-world changes to phone formatting,
parsing and checking rules.

Proposed fix:

The package needs to be updated and kept up to date with the latest release
even in stable versions, otherwise it risks becoming entirely useless.
