+Phone Number Utility is part of the Symbian Text Utility Component (<codeph>etul.dll</codeph>)
+and it offers methods for parsing and validating phone numbers. </p> <p>Examples
+of valid phone numbers: </p> <ul>
+<li id="GUID-C6D1DCE8-CC29-5C1D-840F-E22390F3F878"><p>1. +358501234567 </p> </li>

+</ul> <p>Even though both of the above examples are valid phone numbers, only
+the first one is accepted as a phone number by many systems. To convert the
+second number to the first number, parsing methods of Phone Number Utility
+can be used. </p> </section>
