Ideas for dial in line sharing?

I've got a single phone line that I'd like to use to dial in to a RH8
machine and set up a ppp connection (from my cellphone). This same line
goes to other telephones, answering machine, etc. I'm thinking the RH8
machine could watch for a ring (either the word RING or a high on the RI
pin). It would then start a timer. If it rings again between 30 and 60
seconds later, it would answer as a data call. Otherwise it would not
answer. When I want to dial in, I'd call the line, let it ring once, then
hang up. I'd wait 30 seconds, then dial out with the modem capability of
the cellphone. Ideally that call arrives in the 30-60 second period and
the RH8 machine tells the modem to answer. Does this sound workable? How
are others handling incoming calls on lines that are shared as voice
lines?

THANKS!!!
