Hi,
this reply means that the UAS couldn't match a sequential request
(in-dialog request) with any of the dialogs he knows; reason: maybe the
dialog already ended from UAS point of view or the UAS is not able to
match (some headers are mismatching).
what;s the method you are getting this reply for?
regards,
bogdan
