I have a question regarding to SIP over WebSocket implementation. I have changed kamailio.cfg file accordingly with websocket configurations. However, when I am trying to run Kamailio, now I am getting 3 errors on the same line which is "syn_branch = 0". What could be the issue? And How it is possible to fix it?

Thank you in advance.
