Local messages are malformed in Kamailio 4.4.X. For
example after receiving
an error response (603) to an INVITE message, the ACK is generated with
header Max-Forwards concatenated to header CSeq and double CRLF, which is
wrong.
Funny thing, I just discovered something with line endings as well
when replying locally from config file.
Kamailio seems to reply with mixed line terminators when flag --no-crlf
is used with sipsak.
How to repeat:
kamailio.cfg

$ sipsak -H localhost -s sip:127.0.0.1:5060 -v -f test/unit/60-message-sdp9.sip --no-crlf
tcpdump shows following headers and line terminators:

200 OKCRLF
Via...CRLF
From...LF
To...LF
Call-ID...LF
CSeq...LF
Content-Type...CRLF
Server...CRLF
Content-Length...CRLF
CRLF

Maybe these two findings are related. I tested with master version.
