Well your in luck. All the nec features are retained. The only odd-ball
stuff the common user has had to deal with is the line key lights don't
appear like they use to. Originally we had the first 4 marked as local1
-4 then the rest toll1-8. Now when a call comes in button #15 flashes,
and when they pick it up to answer it is dropped on the next available
light (starting at local1). So far it hasn't been a big deal - just
takes some getting use to.
If all else fails you could let the nec answer the calls, and have
asterisk be extensions on the nec ..... but seems like such a waste.

I hope you have better luck than I with the remote extensions.... the
iax2 link to my vpn'd offices is a little to choppy... but getting
better.

Good Luck!
