on section 8.1.1 RFC 3261: " A valid SIP request formulated by a UAC
MUST, at a minimum, contain the following header fields: To, From, CSeq,
Call-ID, Max-Forwards,and Via;"
I'm sending to OpenSIPs a SIP INVITE (with SIPSAK) with these headers:
Via, From, To, Call-ID and Cseq (without Max-Forwars); OpenSIPs accept
the message without problems. Is this the expected behavior?
Without other Header (between the six) the result is:
ERROR:tm:t_lookup_request: too few headers
