[Freeswitch-users] transfer_fallback_extension

[Raphael Lechner]

Hi,

I have created the following dial plan for that.

If the call is not answered after 30 seconds then the call is going back to the initial caller and on the display is showing (NO_ANSWER)>>orig_caller_id_name>>orig_caller_id_number.

<extension name="Local_Extension">
  <condition field="destination_number" expression="^([0-9][0-9])$">
    <action application="export" data="dialed_extension=$1" />
    <action application="bind_meta_app" data="1 b s execute_extension::dx XML features" />
    <action application="bind_meta_app"
      data="2 b s record_session::$${recordings_dir}/${caller_id_number}.${strftime(%Y-%m-%d-%H-%M-%S)}.wav" />
    <action application="bind_meta_app" data="3 b s execute_extension::cf XML features" />
    <action application="bind_meta_app" data="4 b s execute_extension::att_xfer XML features" />
    <action application="set" data="transfer_ringback=$${hold_music}" />
    <action application="set" data="call_timeout=30" />
    <action application="set" data="hangup_after_bridge=true" />
    <action application="set" data="continue_on_fail=NO_ANSWER" />
    <action application="hash" data="insert/${domain_name}-call_return/${dialed_extension}/${caller_id_number}" />
    <action application="hash" data="insert/${domain_name}-last_dial_ext/${dialed_extension}/${uuid}" />
    <action application="set" data="called_party_callgroup=${user_data(${dialed_extension}@${domain_name} var callgroup)}" />
    <action application="hash" data="insert/${domain_name}-last_dial_ext/${called_party_callgroup}/${uuid}" />
    <action application="hash" data="insert/${domain_name}-last_dial_ext/global/${uuid}" />
    <action application="hash" data="insert/${domain_name}-last_dial/${called_party_callgroup}/${uuid}" />
    <action application="set"
      data="effective_callee_id_name=${user_data(${dialed_extension}@${domain_name} var effective_caller_id_name)}" />
    <action application="set" data="effective_callee_id_number=${dialed_extension}" />
    <action application="log" data="INFO effective_callee_id_number=${dialed_extension}" />
    <action application="log"
      data="INFO effective_callee_id_name=${user_data(${dialed_extension}@${domain_name} var effective_caller_id_name)}" />
    <action application="export" data="alert_info=http://localhost/;info=internal" />
    <action application="log" data="INFO alert_info=${alert_info}" />

    <condition field="${last_bridge_hangup_cause}" expression="^NO_ANSWER$">
      <action application="log"
        data="INFO NO_ANSWER -- ${dialed_extension}(NO_ANSWER)>>${orig_caller_id_name}(${orig_caller_id_number})" />
      <action application="export"
        data="origination_caller_id_name=${dialed_extension}(NO_ANSWER)>>${orig_caller_id_name}(${orig_caller_id_number})" />
      <anti-action application="set"
        data="effective_callee_id_name=${user_data(${dialed_extension}@${domain_name} var effective_caller_id_name)}" />
    </condition>

    <action application="bridge"
      data="{effective_callee_id_name=${effective_callee_id_name},effective_callee_id_number=${effective_callee_id_number},origination_caller_id_name=${origination_caller_id_name}}user/${dialed_extension}@${domain_name}" />
    <action application="transfer" data="${last_sent_callee_id_number}" />
  </condition>
</extension>
