[Freeswitch-users] About Call Transfer

[王聡]

Hey all,

I’m trying to add a new function to my callcenter server which allow peers transfer their call to other operator.
I added the following configure into my dialplan:

 <action application="bind_meta_app" data="4 b s execute_extension:att_xfer XML features”/>

And features.xml showed like:

    <extension name="att_xfer">
     <condition field="destination_number" expression="^att_xfer$">
       <action application="read" data="3 6 'tone_stream://%(10000,0,350,440)' digits 30000 #"/>
       <action application="set" data="origination_cancel_key=#"/>
       <action application="att_xfer" data="user/AA-${digits}@$${domain}"/>
     </condition>
    </extension>

This should works when *4 was pressed and att_xfer activated, however when I test this dialplan, freeswitch showed the log as:

The anonymous is my test phone and BB-000004 is operator. I pressed *4 on operator sip phone and got the error above. Freeswitch seems to execute the playback on bind_meta_app.

Is there any advice on this problem?
