Launch Lync 2013 from windows store app

Hi Everyone,

I have been trying to Launch Lync for audio/video call, chat, phone call with a Uri protocal like how we do in skype.

<Extension Category="windows.protocol">
   3:           <Protocol Name="skype"/>
   4:         </Extension>
   5:         <Extension Category="windows.protocol">
   6:           <Protocol Name="tel"/>
   7:         </Extension>
   8:         <Extension Category="windows.protocol">
   9:           <Protocol Name="sms"/>
  10:         </Extension>
  11:         <Extension Category="windows.protocol">
  12:           <Protocol Name="message-skype-com"/>
  13:         </Extension>
  14:         <Extension Category="windows.protocol">
  15:           <Protocol Name="message-messenger"/>
  16:         </Extension>
  17:         <Extension Category="windows.protocol">
  18:           <Protocol Name="audiocall-messenger"/>
  19:         </Extension>
  20:         <Extension Category="windows.protocol">
  21:           <Protocol Name="videocall-messenger"/>
  22:         </Extension>
  23:         <Extension Category="windows.protocol">
  24:           <Protocol Name="audiocall-skype-com"/>
  25:         </Extension>
  26:         <Extension Category="windows.protocol">
  27:           <Protocol Name="videocall-skype-com"/>
  28:         </Extension>
As you can see Skype has many protocols to launch 

I have found something sip:someone@domain.com which opens lync chat window. But I want the other options as well  like how we have in skype

Any kind of help is highly appreciated.

thanks
