Open Skype through ionic app

I want to open Skype from my Ionic app. I have seen many answers but nothing seems to work.

Answers like :

All the solutions works fine in browser but not in my device.

I have installed the necessary cordova plugins like:

cordova plugin add com.lampa.startapp

cordova plugin add cordova-plugin-inappbrowser

cordova plugin add org.apache.cordova.device

Also i have add:

  <plugin name="cordova-plugin-whitelist" version="1" />
  <allow-intent href="skype:*"/>

in config.xml.

Has someone faced the same problem?

Any help would be appreciated!

Ok so it was simple. The code that i used is:

$scope.skypeID = skypeID;
           startApp.set({ /* params */
             "action": "ACTION_VIEW",
             "uri":  "skype:"+skypeID   

I used the said code and it works in Android but NOT in Ios. Anything wrong with it?
