Hi list, I'm already searching in FS manual several hours but cannot find the solution. My task is to receive SIP call from remote SIP device (registered to FS like User: 1005@192.168.8.6), using DIALPLAN route it back to SIP channel with the same (or increased) destination_number back to the remote SIP device. I.e. make such simple loopback in FS. Tested DIALPLAN extension is <extension name="Loopback"> <condition field="destination_number" expression="^(5000)$"> <action application="bridge" data="sofia/$${domain}/1005"/> </extension> The call is looped back to SIP channel but with destination_number 1005. Is there any way to enforce to this bridged outbound call the destination_number based on destination number of inbound call (which comes with destination number 5000) ? Thank you in advance Petr B.
