I have a buddy that is looking at getting an NEC Elite IPK II system.

Configuration is going to be a 6x10 with maybe 2-3 IP Phones.

I'm not familiar with NEC's products so I figured I would ask here. Are there any known issues with this system that I should have him ask his vendor about? Is it near it's EOL with NEC? Are upgrades fairly reasonable?

The vendor seems reputable and all that. Just trying to help him make a more informed decision.
