Hi, AFAIK headers "Via", "Route" and "Record-Route" can appear multiple times in a message (not just multiples values in each header), for example:
INVITE sip:asdasdasd SIP/2.0 Via: xxxxxxxx, xxxx Via: xxxxxxx Via: xxxxxxxxxxx ... I don't find in RFC 3261 which exact headers can appear multiple times in a message. For example: can "Require" header appear multiple times? Considere this case: INVITE sip:qweqweqwe SIP/2.0 Require: replaces Require: wrong_value Should the UAS reply 420 (Bad Extension) because the second "Require" is wrong? or should it accepts the message since the only "Require" header it must inspect is the first one? Any point to RFC 3261 is welcome :) Thanks for any explanation. -- Iñaki Baz Castillo _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
