Determine if it's a cellular call or VOIP call.

Hi Everyone,

I am working on an app where I need to determine if a call whether incoming or outgoing is a normal (cellular) call or VOIP call?

And yes, if we can identify if it's a VOIP call, can we also identify the name of the app used for the call?

Determine if it's a cellular call or VOIP call.
