Starting-a-Call.md

+For starting a call you can just open the Reve SaaS Dashboard and from contacts page, you can place call.
+
+But if you want to place call directly from your app, you need to use the following apis. 
+
+**1. Placing a free audio call :**
+
+`ReveSaaS.makeAudioCall(activity, numberToCallWithCountryCode);`
+
+*Example*
+
+` ReveSaaS.makeAudioCall(MainActivity.this, "+8801844097722");`
+
+**2. Placing a free videocall :**
+
+`ReveSaaS.makeVideoCall(activity, numberToCallWithCountryCode);`
+
+*Example*
+
+` ReveSaaS.makeVideoCall(MainActivity.this, "+8801844097722");`
+
+
+**3. Placing a paid call (audio only):**
+
+`ReveSaaS.makePaidCall(activity, numberToCallWithCountryCode);`
+
+*Example*
+
+` ReveSaaS.makePaidCall(MainActivity.this, "+8801844097722");`
