Anyone know the specifics?
Short answer: Two names for the same thing.
Long answer: VoIP is one form of digital phone service.
Most "Digital Phone" offerings use IP and moves the data over
your regular Internet DSL/Cable/Fiber connection, so that makes
them VoIP by definition. Digital Phone Service *could* also mean
it uses a separate, dedicated channel and/or a different protocol,
but that's not common.
So in most cases the issues are exactly the same ;
- Power backup (if the cable/DSL modem and/or router is down,
the phone line goes with it)
- Latency/quality (it's a LOT better today than a couple of
years ago, but can still cause problems for control panels)
- User interference (users mess with the router, unplug wires,
change service..)
- Reliability (Internet Service Providers frequently cut off
service for hours at a time to do maintenance or upgrades)
If you hook up burg systems to VoIP/Digital, make sure both you and
the customer understands the limitations, or you will both be very
disappointed...
