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: freeswitch@devil4> show channels API CALL [show(channels)] output:
