I would encourage you to try it out. The expectation on the other side is extremely low -- no one expects a conversation or honestly more than a two-word pleasantry. And the camera defaults to the back camera, so no one sees anyone's face.

My last call:

  Me: "Hello?"
  Them: "Hi. Can you tell me which can is soup?"
  Me: "Can I see the other one?"
  Them: "This one?"
  Me: "That's cream of tomato."
  Them: "Thank you."
  Me: "You're welcome."
