[SR-Users] Force socket on reply

[Daniel-Constantin Mierla]

Hello,

I haven't understood exactly what you tried? Was it use of 
force_send_socket(...) in onreply_route and didn't work? If yes, what 
version are you runing, there was a fix for such case some time ago:

http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=9dbf735878acc87bab1a0740476f1d106f89412f

Cheers,
Daniel
