isCarrierSpecific() public method

Given a valid short number, determines whether it is carrier-specific (however, nothing is implied about its validity). If it is important that the number is valid, then its validity must first be checked using {@link isValidShortNumber} or {@link #isValidShortNumberForRegion}.
public isCarrierSpecific ( PhoneNumber $number ) : boolean
$number PhoneNumber the valid short number to check
return boolean whether the short number is carrier-specific (assuming the input was a valid short number).
