Can anyone suggest how I can simulate a 911 call with a ALI (Automatic Numbering Information) over SIP to Asterisk? Will Asterisk be able to receive this information?

OK, first... I think of asterisk as "the telephoney toolkit" rather than a PBX. The answer to "can asterisk do that" is always yes. But somethings are easier to do. Recall you have source code so you can do anything.

ALI != Automatic NUMBERING Information

What you are asking about is huge! I think standards are still emerging so you really need to define exactly what you want.

Try reviewing these publications first: http://www.its.dot.gov/ng911/ng911_pubs.htm

Esp look over: NG9-1-1 System Description and Requirements Document

Then use google and the following terms: "LoST sip 911 i3 ecrit"
