Alex, What you are looking for is sip_auto_answer ( <http://wiki.freeswitch.org/wiki/Variable_sip_auto_answer> http://wiki.freeswitch.org/wiki/Variable_sip_auto_answer) that tells the phone to auto-answer the call as long as your phone supports it and is configured properly. If the variable doesnt work but your phone supports it, then it is a matter of adding a SIP header the phone understand. The SIP header is added by prepending {sip_h_...} On my Aastra phones, the SIP header is Call-Info so it should look like this: {sip_h_Call-Info=;auto-answer=0} Benoit Raymond AMI Concept Inc.

What I'm trying to do here is really aimed at callback. The user hits a web button and then Freeswitch pages his phone and then places an outbound call. "api originate user/0095302 02070601234 XML dp0095" Does the trick, by calling 0095302 and then on answer calls 02070601234. What I'm trying to do is to not require the user to lift the handset and it has been suggested that paging is the way to do it. It's not a very true use of multicast, but might it work?
