Normalizing

Signature	char *CPPhoneNumberCopyNormalized(char *);
Available in	? –

CPPhoneNumberCopyNormalized returns a normalized copy of a phone number.

extern char *CPPhoneNumberCopyNormalized(char *);

...
	char *pn = CPPhoneNumberCopyNormalized("+1 (555) 555-5555");
	printf("%s\n", pn); // 15555555555
	free(pn);

Comparing

Signature	BOOL CPPhoneNumbersEqual(const char* number1,const char* number2, CFStringRef country);
Available in	? –

CPPhoneNumbersEqual compares two phone numbers. It will automatically normalize the number, and add an country code if the number does not contain one. It is extremely useful, if you have to compare an incoming call against an user supplied phone number.

You could compare two German phone numbers like this:

extern "C" CFStringRef CPPhoneNumberCopyHomeCountryCode();
extern "C" BOOL CPPhoneNumbersEqual(const char* number1, const char* number2, CFStringRef country);

BOOL equal = CPPhoneNumbersEqual("+49302270", "0302270", CPPhoneNumberCopyHomeCountryCode()); //should return YES, if you're phone is in Germany/using a german SIM Card
