I just tried to set up the 2-step verification( log-in to my Outlook.com Mail). 

I don't want to use an App every time I log in to my Outlook.com account. I remember you were able to use the Voice Call Verification Method, before. Did Microsoft remove it? If not, how to set up my 2-step-verification so I get Voice Calls, again?

/ I tried searching the NET and this website- no luck! T__T
