Phony.split(international_number) splits a normalized international number into its components, like so:
[CC, NDC, LOCAL1, LOCAL2, ..., LOCALN].
You really need to give it a normalized phone number WITH a country code, so:
Phony.split('3643532') # This ... no.
Phony is happy with these:
Phony.split('43198110').should == ['43', '1', '98110']
Phony.split('33112345678').should == ['33', '1', '12','34','56','78']
Phony.split('4976112345').should == ['49', '761', '123', '45']
Phony.split('3928061371').should == ['39', '2', '806', '1371']
Phony.split('41443643532').should == ['41', '44', '364', '35', '32']
Phony.split('15551115511').should == ['1', '555', '111', '5511']
Phony.split('6491234567').should == ['64', '9', '123', '4567']
Phony.split('41800334455').should == ['41', '800', '33', '44', '55']
It handles missing pieces gracefully.
Phony.split('4144').assert == ['41', '44', '']
Phony.split('4144364').assert == ['41', '44', '364']
Phony.split('414436435').assert == ['41', '44', '364', '35']
