On CASCADE means that if you eliminate or update a PK, it will cascade to 
the refereced keys. If you eliminate the last phone number, you're just 
eliminating rows that reference th PK, so no CASCADE is done.

Those CASCADE are more like, if you eliminate the contact, all the info of 
that contact will be eliminated.
