I just upgraded a Norstar MICS from 12 analog trunk lines to a PRI (other end 
being Asterisk) -- we lost all line appearances as well.  When using digital 
lines the density is generally understood to be too great to have line 
appearances.  Indeed the concept of a telephone "line" is no longer valid -- 
you have voice channels that can be any telephone line or number.

Perhaps a better idea is to have extension appearances (similar to a CAP 
module) and a number of parking slot appearances.  This, IMO, is far more 
worthy of development work, as it scales much better.  Call pickup still 
works from any phone in the pickupgroup, so picking up a ringing line should 
not be any different.
