Hmm, my SPA525G doesn't auto-answer a page however my SPA92X do.

The above is for paging, I use a macro to perform an intercom, here is 
what I have in my extensions.ael.

<context> {
	
         _8XXX => {
                 &sip_intercom(${EXTEN:1});
         };

};


macro sip_intercom( extension ) {
         ChanIsAvail(SIP/${LOCAL(extension)},s);
         NoOp(**** Status : ${AVAILSTATUS} ****);
         switch(${AVAILSTATUS}) {
                 case 1:
                         Set(TIMEOUT(absolute)=1920);
                         SIPAddHeader(Alert-Info: Ring Answer);
                         SIPAddHeader(Alert-Info: Info=Alert-Autoanswer);
                         SIPAddHeader(Alert-Info: info=ringAutoAnswer);
                         SIPAddHeader(Call-Info:\;Answer-After=0);
                         SIPAddHeader(P-Auto-Answer: normal);
                         SIPAddHeader(Answer-Mode: Auto);
                         Dial(SIP/${LOCAL(extension)});
                         Hangup();
                         break;
                 case 2:
                         Busy();
                         Hangup();
                         break;
                 case 5:
                         Congestion();
                         Hangup();
                         break;
                 default:
                         PlayBack(invalid);
                         Hangup();
                         break;
                 };
         return;
         };
