Hi. We call an extension called "netcat" which is configured in this way: <extension name="netcat"> <condition field="context" expression="public"/> <condition field="destination_number" expression="^netcat$"> <action application="log" data="INFO extension netcat"/> <action application="socket" data="127.0.0.1:8085 async full"/> </condition> </extension> The inbound call is correctly routed to a netcat socket listening on localhost:8085. When I get the socket connect, I issue the following commands: connect ... sendmsg call-command: execute execute-app-name: answer ... sendmsg call-command: execute execute-app-name: bridge execute-app-arg: sofia/external/external_number@external_domain The bridge is done correctly but the media stream is not bidirectional: • Aleg can listen Bleg • Bleg can speak but doesn't hear Aleg The strange thing is that if I put on hold and unhold Aleg with: sendmsg call-command: execute execute-app-name: hold .. sendmsg call-command: execute execute-app-name: unhold the media stream is recovered correctly: Aleg and Bleg can speak/listen each other. I attach pastebin for completeness: • Freeswitch log: http://pastebin.freeswitch.org/pastebin.php?dl=20656 • Outbound socket log: http://pastebin.freeswitch.org/pastebin.php?dl=20657 Thank you for your help.
