[Freeswitch-users] att_xfer application

Wed May 14 06:22:57 EDT 2008

Hi,

Currently I need to set up attended transfer to phones which dont have 
any support to it.
So, made a simple extension in features.xml which read the number and 
supply it to att_xfer app:

<extension name="att_xfer">
    <condition field="destination_number" expression="^att_xfer$">
        <action application="read" data="3 4 sounds/mellekek.wav 
attxfer_callthis 30000 #"/>
        <action application="att_xfer" 
data="sofia/default/${attxfer_callthis}"/>
      </condition>
</extension>

then bind it to dtmf 3 in default.xml Local Extension with:

<anti-action application="bind_meta_app" data="3 a a 
execute_extension::att_xfer XML features"/>

I can activate this feautre, it's hold the bleg and call the 3rd party, 
but when I try to make the transfer with dtmf 0 than it hangup all legs.
For me it's look like that FS hangup the channels than try to bridge them.
Here is the console log:

My question is if its a bug or I did something wrong?
I used the lastest trunk on Ubuntu linux.

Thanks,
