The Elite 192 has the EXACT SAME programming as the IPK, there are only a couple of differences and they would not be involved in what you're doing.
Find a new NEC dealer.
I upgrade 192 systems to IPK all the time, same cabinet, same cards, different cpu and slightly different software.
I've actually just installed a 192 last week.
If it ain't broke, don't replace it. Your dealer is probably setting you up for trying to sell you 'all new modern' stuff, don't fall for it.
