I'm trying to handle freeswitch configuration with lua (in particular sofia conf) but unsuccessfuly.

I see that my lua script works when freeswitch requests sofia configuration but I am not able to push xml responce to it. I set XML_STRING variable but nothing happens in freeswitch. I even tried to put nil to XML_STRING and freeswitch even does not throw an error.

I've installed freeswitch from freeswitch deb packages (on Debian 8).

Package version: 1.6.10~17~726448d-1~jessie+1

I've attached to this letter some configs, lua script and freeswitch log.

I appreciate your help.

Best regards,
