Good Afternoon.

I'm leaving Asterisk ( yayyyyyyyyyyyyy) and was curious in trying out the Call Center feature,  uuid-standby , now i created a dialplan and I'm able to connect a caller to an agent.
Now by my assumption as soon as the caller disconnects the agent should be trow back ( transfer) into the loop (4099 ext.) but instead i get an hangup and the sip client terminates the call.

Any ideas ?

Sample Dialplan

<extension>
  <condition field="destination_number" expression="^(4099)$">
    <action application="set" data="res=${callcenter_config(agent set uuid ${caller_id_number}@${domain_name} '${uuid}')}" />

    <action application="set" data="res=${callcenter_config(agent set type ${caller_id_number}@${domain_name} 'uuid-standby')}" />
    <action application="set" data="res=${callcenter_config(agent set status ${caller_id_number}@${domain_name} 'Available (On Demand)')}" />

    <action application="set" data="res=${callcenter_config(agent set state ${caller_id_number}@${domain_name} 'Waiting')}" />
    <action application="set" data="cc_warning_tone=tone_stream://%(200,0,500,600,700)"/>

    <action application="answer" />
    <action application="playback" data="$${hold_music}"/>
    <action application="transfer" data="4099"/> <!-- Remove this if you just want to get a single call -->

  </condition>
</extension>
