(The PSAP provides battery toward the CO). ANI is provided using MF tones. The PSAP equipment must take the ANI and use it to submit a database query to lookup the caller's address (ALI - automatic location identification) to an external database that is usually operated by the ILEC or its contractor. The ANI and ALI information must be presented to the 911 call taker immediately upon answering the call. There is definitely a place for Asterisk in the public-safety telecomm field, but a lot of work would be needed for it to handle calls in a PSAP. If you're interested in learning more about PSAP equipment, take a look at the web pages for Plant Equipment, Inc, Positron, Inc. and Zetron, Inc.
