Brilliant - thanks. I may have to do a little "see also" in the places I 
was looking in the wiki

> On my Aastra phones, the SIP header is Call-Info so it should look

>     <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

> 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

> very true use of multicast, but might it work?
