Linphone 3.3.2 sends UDP packets of length 4, containing double CRLF assume as keep alive method. These are invalid SIP packets, since a double CRLF is only ignored by a SIP server when received over connection oriented transport protocols like TCP and STCP.An alternative keep alive method should be used instead, preferably OPTIONS when needed.http://tools.ietf.org/html/rfc5626#section-3.5.1 Regards, Mikael
I was wrong, the keep alive packets contains "jaK\0" and not CRLF. Is this a standardized keep alive method for UDP? Where can I read about it?
