Control of Desktop Phone From a Host Application Using Data

      A method for controlling the telephony functions of a
desktop telephone is disclosed.  Control of the telephony port of a
telephone instrument is done by wrapping it back to the data port of
the same instrument.

      Instead of requiring special code in a telephone switching
system, this uses the data feature of the telephone.
      Configuration:
      User has telephone device on desk top with a wrap cable that
connects the data port to the telephony port.  See Fig. 1.

      Telephone system has a data connection to a host computer
system.
      These are called servers.  See Fig. 2.

      Scenario to place a call on behalf of user from host computer
system:
1.  Host sends a command on server communication line to establish a
data connection between the server and the user's phone.
2.  Host computer sends telephony command to place a call from the
user's phone.
     a.  Host sends data to server.
     b.  Server sends data stream to telephone system as "data for
the data port"
     c.  Telephone system sends this "data" to the desktop phone data

 d.  Since data port and telephony port are wrapped, the telephony
port receives this "data" as a command.
     e.  Desktop telephone executes the telephony command.
     f.  Response to the telephony command is sent back out of the
