CSeq is a mandatory SIP header. It must be present in all SIP request and responses. Im not aware what happens if there is no CSeq header in a SIP message. Some expert can throw light on it. Regards, Ayyanar

Here I am with a doubt that, Wat the UAS is going to do when it receives multiple "To" or "From" headers in the initial INVITE??? Do we need to send 400 response for that??? RFC 3261 doesn't say to send 400 response. And is it ryt way of giving the preference to the first "To" or "From" headers if multiple headers present?? And also watz the response of UAS if no Max-Forward header in the INVITE??. If proxy is in between, proxy will had Max-Forward and sends. If no proxy and INVITE directly receives to end UAS, watz the response of UAS?? -- Cheers vrnkgt _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors Please do not print this email unless it is absolutely necessary.
