I'm trying to program an extension in the dialplan to do an intercom
announce. I read through the wiki and wrote the following based on what
I thought I understood from it, but it's not working the way I expect:

<extension name="Global Announce">
<condition field="destination_number" expression="^89$" break="never">
<!--These params effect the outcalls made once you join-->
<!-- First we set the api_hangup_hook to kick everyone from the
conference when the initiator hangs up. -->
<action application="set" data="api_hangup_hook=conference 89
kick all"/>
<action application="answer"/>
<action
application="export"><![CDATA[sip_h_Call-Info=<sip:$${domain}>;answer-after=0]]></action>
<action application="export"
data="sip_invite_params=intercom=true"/>
<action application="export" data="sip_auto_answer=true"/>
<!-- If the above exports do not product the desired results,
try passing the variables as commented out below -->
<!--<action application="conference_set_auto_outcall"
data="{sip_auto_answer=true}sofia/gateway/asterlink.com/19184238080"/>-->

<action application="set"
data="conference_auto_outcall_caller_id_name=$${effective_caller_id_name}"/>
<action application="set"
data="conference_auto_outcall_caller_id_number=$${effective_caller_id_number}"/>

<!-- Keep the call time down to a few seconds. If calling
phones that don't auto-answer you may want to -->
<!-- increase this value to something a bit more persistent than
5 seconds. -->
<action application="set" data="conference_auto_outcall_timeout=5"/>


<!--if you don't need to hear the participants, as in a page
instead of multi-party intercom -->
<!-- then use "mute" instead of "none" as the
conference_outcall_flags below. -->
<action application="set"
data="conference_auto_outcall_flags=mute"/>

<!-- If you'd like to say something to the participant and have
cepstral configured and installed, now's the time. -->
<!--<action application="set"
data="conference_auto_outcall_announce=say:You have been called into an
emergency conference"/>-->

<!--Add as many of these as you need, These are the people you
are going to call-->
<!-- We have commented these out since we have the list of
participants down below as a catch-all in case the caller_id -->
<!-- of the initiating party doesn't match the phones being
called. -->
<!--<action application="conference_set_auto_outcall"
data="sofia/gateway/asterlink.com/19184238080"/>-->
<!--<action application="conference_set_auto_outcall"
data="sofia/default/888@conference.freeswitch.org"/>-->
</condition>

<condition field="caller_id_number" expression="^303$" break="never">
<antiaction application="conference_set_auto_outcall"
data="user/303@$${domain}"/>
<antiaction application="set"
data="conference_auto_outcall_flags=mute"/>
</condition>

<condition field="caller_id_number" expression="^304$" break="never">
<antiaction application="conference_set_auto_outcall"
data="user/304@$${domain}"/>
<antiaction application="set"
data="conference_auto_outcall_flags=mute"/>
</condition>

<!-- Now we check the destination again and act accordingly. -->
<condition field="destination_number" expression="^89$">

<!-- Please note that you can also designate your own conference
bridge instead of default and enable only the options you desire.-->
<!-- I have kept the default conference in this example so that
you can get this to work before changing the conference to something -->
<!-- with your own options enabled. In this way the example
provided here should work and you can fine tune your conference to your -->
<!-- desire. See the config file
autoload_configs/conferences.conf.xml for more information on how/what
to do or consult the Wiki -->

<!-- IMPORTANT IMPORTANT IMPORTANT - use ONLY ONE of the two
options below -->

<!-- OPTION 1 -->
<!-- If your phones are all isolated from one another (not in
the same room, uncomment the following line -->
<!-- <action application="conference" data="89@default"/> -->

<!-- OPTION 2 -->
<!-- If you encounter feedback issues use the conference profile
given on this page -->
<!-- and comment out the application line in OPTION 1 above -->
<!-- and un-comment the line below -->
<!-- <action application="conference" data="89@intercom"/> -->


<!--After the hangup, we kick everyone in the conference to
cause a hangup. -->
<!--This shouldn't be necessary since it should be handled above
in the api_hangup_hook. -->
<action application="conference" data="89 kick all"/>
</condition>
</extension>
