I must have misspoke, or you misunderstood... my telco is happy to help 
me get set up for PS/ALI. In fact, that's the only method they've 
offered for me to be able to do E911 from my VOIP termination service 
(which is not yet installed <G>). What they will _not_ do is manage the 
ALI information for my PRI line(s) and DID numbers, except at 
installation and service-move time only. I personally don't blame them 
one bit for this position; if they can help me get set up for PS/ALI, 
that's the best solution for all concerned.
