[comp.dcom.telecom] phone patch

TEDEMKO%SUNRISE.BITNET@MITVMA.MIT.EDU (10/05/88)

does anyone have a quick (meaning EASY) circuit out there that will do the
following:

person calls in on telephone line #1 if no one answers line one the
call is automatically picked up and connected to line #2 which should
be just a dial tone.
when the caller complets using the dialtone from line #2 and hangs up his
phone the circuit should disconnect both lines and wait for
the next call.

thanks for any help ya can give me
