Do you use the AnI II digits for anything?  If not, call the telco and 
tell them to just send ten digits.  When I used to have some T1s with 
UCN, they sent the ANI II digits in a separate field specifically for 
that.  I could see them in PRI debug on the console.  Now with Global 
Crossing, I get *ANI*DNIS* which is pretty funky.
