If the Genie requires a yes or no response, you can press 1 for "Yes" or 2 for
"No."
You can also press 2 to cancel a command. For example, if you
call someone and you change your mind, press 2 to cancel the action.
Important: Vocera uses the 1 and 2 keys for its
functionality and hence does not fully support calling Interactive Voice Response (IVR) phone
numbers while you are accessing the Genie from a phone.
