[Mohamad Arag]

just opened my Messenger beta on my Lumia 640XL and an icon of a phone was there. Tried to make a call and it worked.

closed the app and reopened it and it was gone.

don't know how to get it back.

It's a server side effect.

They are testing it randomly & it appears/disappears randomly.

Next update is likely to bring it for more users according o mspoweruser
