I haven't really gotten too far into this, but I was wondering just what 
'features' of the NEC phones (DTH-16D-1(BK)TEL) I'll be able to work 
with from *?  I'm currently getting some pressure to ensure that all the 
little bells, whistles, and lights will continue to work as they 
currently do.  I'm also afraid that if the phones would end up becoming 
'dumb' (or should I say dumber than they already are), this could kill 
my plan for an NEC to * migration, and would be a huge loss for * in my 
company, not to mention a huge extra expenditure for ACD Plus otherwise.

Thankfully, regardless of the outcome of everything else, I will be 
setting up one machine to interact with some IAXy's for remote extensions.

thanks,
