[SR-Users] usage of app_mono : how to communicate results back to config file

Hi, I am using app_mono module and building my logic in c# app. I am unable to understand how to send the decision back to kamalio.cfg. More precisely: I would like my routing logic to allow specific user names though they are not registered as subscribers. Like: translate@myip.cyracom.com<mailto:translate@myip.cyracom.com> I have the logic in c# app which takes $ru and validates such that: Host is myip.cyracom.com User is translate How do I communicate the decision if it is valid or not back to my config script. Do I need to introduce new pseudo variable for this purpose? Thanks, Pranathi
