with this unit http://www.doorbellfon.com/products/28wt/28wt.htm
you can run your existing telephone line into the line in port, then
take the line out to your x100p, now when a call come in from the
telephone line it will ring with a standard cadence, 
but a call from the doorfon unit will ring with another cadence
No just use the dring feature in zapata.conf to route the calls based
on the different cadence
