We have had great results with conventional Viking POTS door phones
connected to an FXS port on an Adtran TA9xx or an ATA.  Only one pair
needed, no problems with long PoE ethernet loops to a pedestal at the
end of the driveway, etc.

Substantially less money than the SIP products especially if you have an
analog port available.  This may change as they are made in greater
quantities down the road.
