Call back is quite cool where users are in areas where no callshops, internet and other calling facilities are available except mobile phones, users will pay both calls.

There might be some other usages as well.

yes callback to caller id

Okay, here's a dialplan snippet that I used to successfully do the autocallback. In my case I used ext 1001 as the customer and portaudio as the "agent" if you get my meaning. Extension 1001 dials 9902, hangs up, and immediately the api_hangup_hook's originate command is executed. In this case it calls portaudio/auto_answer for the A-leg and user/1001 as the B-leg. I don't claim that it's the prettiest thing in the world but it definitely works. You'll need to adjust according to your specific situation.

  <extension name="callback-test-answer-ib-call">
    <!-- From mailing list - a question about how to do this:
        Caller calls in, ring (no answer), capture Caller ID, wait for caller to hangup
        Generate outbound call to captured caller ID number
        Only use dialplan, no scripting
    -->
    <condition field="destination_number" expression="^9902$">
      <action application="pre_answer"/>
      <action application="set" data="callbacknum=${caller_id_number}"/>
      <action application="log" data="INFO Callback number is '${callbacknum}'"/>
      <action application="set" data="api_hangup_hook=originate portaudio/auto_answer CBTEST${callbacknum}"/>
      <action application="sleep" data="10000"/> <!-- wait 10 sec for caller to hangup, otherwise we hangup -->
      <action application="hangup"/>
    </condition>
  </extension>

  <extension name="callback-test-generate-ob-call">
    <condition field="destination_number" expression="^CBTEST(\d+)$">
      <action application="bridge" data="user/$1"/>
    </condition>
  </extension>


Let us know how it goes. BTW, what is the reason for this type of scenario? Just curious.
