[Freeswitch-users] Bridge problem from outbound socket

[Denis Gasparin]

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 at 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.
