Hello, Everything works fine if I run Proxy without TLS disabled. I tried both TCP/UDP, it works fine. For TLS, Registration went fine however Proxy responds "513 Message too big" . I don't see any wrong headers in the message. The length is almost same for TCP and TLS invite message, the only change is sip and sips. Any C file I need to modify?
