Both systems are very good at what they do.
The IPK series is an Elite with added Voip software and hardware (The IPK still uses the same programming as the Elite and some of it goes way back to the E-Pro series).
The Aspire was built from the ground up to be a Voip system. ( It uses the same software programming as the i series also).
The IPK must use different cards to get LCR, Caller ID, Caller ID scrolling, and ACD.
The Aspire has all this built in albeit you have to have a different CPU or Upgrade chip.
So I would have both dealers give you a demo.
Remember the system is only as good as its installed and programmed.
And dont forget service after the sale!
