I haven't reviewed your traces (and only was vaguely following this thread), but I'll note that just because something works with a server or client doesn't mean it's right. UA's often (usually) will accept non-compliant requests and sequences; the result however may vary - for example, if a header or parameter appears twice (and is only officially allowed to appear once), it might take the first, the last, or both - or reject it. This is largely a consequence of "be liberal in what you accept, and strict in what you send", and that the spec generally doesn't mandate specific rejections of malformed requests. -- Randell Jesup, Worldgate [email protected] _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
