Wich is working with loopback, is transfer: <extension name="xfer"> <condition field="destination_number" expression="^xfer$"> <action application="read" data="1 15 /opt/freeswitch/sounds/en/us/callie/misc/8000/transfer2.wav callednumber 7000 #"/> <action application="transfer" data="-bleg 664${callednumber}"/> </condition> </extension> <extension name="loop"> <condition field="destination_number" expression="^664([0-9]{4})$"> <action application="bridge" data="loopback/669$1"/> </condition> </extension> (I know there is no need on that loopback in the loop extension, it's just an experimental config about loopback and transfers.) Attended transfer is still a mistery for me. Btw, keeping up experimenting with att_xfer i have found the sofia method a little instable too. It sometimes acts like the user channel i said before. Here is the code that I use: <extension name="loop"> <condition field="destination_number" expression="^664([0-9]{4})$"> <action application="bridge" data="loopback/669$1"/> </condition> </extension> Viktor Hirdetés (x) Váltson most olcsóbb kötelezőre a biztosítás-hu-val. www.biztositas.hu - a kötelező biztosítások kiindulópontja!
