    1.$ PHONE

      The DCL command PHONE invokes the Phone utility. If you issue
      the PHONE command without qualifiers or parameters, the Phone
      utility prompts you for the name of the person you want to
      call (or any other PHONE command) with the default switch hook
      character, the percent sign. The Phone utility also displays
      the title "VMS Phone Facility", and the date, and sets up your
      viewport.

    2.$ PHONE ANSWER

      Use this command to answer a call.

    3.$ PHONE DIRECTORY TAMPA::

      The PHONE command causes the Phone utility to display a
      directory of users available on node TAMPA.

    4.$ PHONE /SWITCH_HOOK="\" /VIEWPORT_SIZE=5  EUGENE::MALCOLM

      The PHONE command defines the SWITCH_HOOK character to be the
      backslash (\), restricts the VIEWPORT_SIZE to five lines, and
      places a call to user MALCOLM on node EUGENE.
