Fixed Dialing Number (FDN) how to create list of allowed numbers programmatically
<p>I would like to create/update the FDN list programmatically. Any idea where this journey should begin? </p>

<p>Maybe somebody before me had similar issue and can help me with this.
For any code examples which will push my work forward I will be very greatful.</p>

<p>I am adding the screenshot (android emulator API17) to make it clear what option I am asking about <a href="https://i.stack.imgur.com/qbhy1.png" rel="nofollow noreferrer">android API 17 - FDN options</a>. 
To get to this menu you need to tap Phone->"open Menu"->Settings->Fixed Dialing Numbers.</p>
