[Freeswitch-users] Paging

[Benoit Raymond]

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 doesn’t 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}

OK, so some more research reveals this example:

   <extension name="rtp_multicast_page">
     <condition field="destination_number" expression="^pagegroup$|^7243">
       <action application="answer"/>
       <action application="esf_page_group"/>
     </condition>
   </extension>


Then there's a suggestion of using a loopback:

<action application="bridge" data="loopback/3456/YOUR_CONTEXT/XML"/>

 

<extension name="rtp_multicast_page">
 <condition field="destination_number" expression="^3456$">
  <action application="set" data="absolute_codec_string=PCMU at 20i
<http://lists.freeswitch.org/mailman/listinfo/freeswitch-users> "/>
  <action application="set" data="jitterbuffer_msec=500:1000:20"/>
  <action application="answer"/>
  <action application="esf_page_group" data="234.5.6.7 23458 30"/>
  </condition>
</extension>

This is beginning to be in the right direction for what I want.

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?
