Answers the phone when you receive a call. If the call comes
    when you are not currently in the Phone utility, a message is
    broadcast to your terminal. If you want to answer the call, enter
    the PHONE command at the DCL prompt and then enter ANSWER at the
    switch-hook (%) prompt. If you do not want to answer a call, you
    may reject the call by using the REJECT command.

    If you are currently using Phone, a message that someone is
    phoning you appears in Phone's standard message line, which is
    located under the command input line on your screen.
