Hello, I am using siptrace module in Kamailio. As you know, it sends a copy of signalling message for specific destination. Like HOMER project. Because of  i won't run main route block in destination, i just  have changed this block like below: request_route {         //do some works.         drop();         exit; } I know it would make a question in your mind why i do this? No problem, Let's come back to question. All things works correct except Replying SIP message. The destination is trying to relay Replying SIP message that it get from siptrace module in other server. How can i disable replying SIP mesages?
