[SR-Users] Local messages are malformed in Kamailio 4.4.X

[Sergey Basov]

Hello.

I make test, currently on kamailio 4.4.0, but as I see in git - tm
module does not changes from that time.
I have normal line termination.
See a dump in attach.
in that dump 10.56.41.33 and 10.56.42.33 is the my mhomed kamailio.
