Asterisk is a telephony PBX and supports presence subscriptions for extension states - if a phone line is busy or not, over a few different SIP presence formats, like SIP dialog-info and SIMPLE.

During a phone call, yes. Not  otherwise.

If you need a full-blown presence server, you should look at Kamailio/OpenSER at http://www.kamailio.org
