I have a somewhat newbie question 

I have a current scenerio were a user registers with freeswitch and makes a call out - Works Perfect!

<include>

  <user id="1000">

    <!-- CGRateS config sample. 

    Make default 1000 user prepaid by adding cgr_reqtype variable to your user -->

    <params>

      <param name="password" value="$${default_password}"/>

      <param name="vm-password" value="1000"/>

    </params>

    <variables>

      <variable name="toll_allow" value="domestic,international,local"/>

      <variable name="accountcode" value="1000"/>

      <variable name="user_context" value="default"/>

      <variable name="effective_caller_id_name" value="Extension 1000"/>

      <variable name="effective_caller_id_number" value="1000"/>

      <variable name="outbound_caller_id_name" value="$${outbound_caller_name}"/>

      <variable name="outbound_caller_id_number" value="$${outbound_caller_id}"/>

      <variable name="callgroup" value="techsupport"/>

      <variable name="cgr_reqtype" value="*prepaid"/>

    </variables>

  </user>

</include>

and then in the default dialplan, i have this

    <!--- CGRateS related extensions -->

    <!-- Place all requests into park app. Notify must be empty so we do not loop. Order Lcr computation -->

    <extension name="CGRateS_Auth">

      <condition field="${cgr_notify}" expression="^$">

        <!---<action application="set" data="cgr_computelcr=true" />-->

        <action application="park" />

      </condition>

    </extension>

Now, i would love to send a call out with the  originate command 

I've tried this - 

originate {origination_caller_id_number='123456789',ignore_early_media=true,originate_timeout=45}sofia/gateway/provider_one/7774262712 &playback(/usr/share/freeswitch/sounds/en/us/callie/voicemail/8000/vm-hello.wav) default CGRates_Auth

That sends the call out and then hangs it up(expectedly)

Is there a way i can replicate my working scenerio(maybe pass in those channel variable) but with the originate command? I'm naively thinking, maybe sending the call to a dialplan first before sending it to a gateway?

Please pardon me if the answers are obvious.
