Thank you for your response.

[OpenSIPS-Users] Minimum SIP Headers
Hello, 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 Thank you Regards ___ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
