[OpenSIPS-Users] CRLF support over TLS

One of my SIP endpoints send CRLF (0x0d 0x0a) messages over TLS 
connections to opensips. Opensips drops TLS a connection to this phone 
after "tcp_max_msg_time" seconds. The same client works fine over TCP 
and CRLF messages are just ignored by a proxy.

rfc3261 section 7.5 says:

> Implementations processing SIP messages over stream-oriented
>     transports MUST ignore any CRLF appearing before the start-line
Is it a bug or did I missed some configuration options to make it work?
