I think you're wrong here. RFC 3261, section 16.7: Until a final response has been sent on the server transaction, the following responses MUST be forwarded immediately: - Any provisional response other than 100 (Trying) - Any 2xx response So it's possible that the proxy has sent provisional responses of different UAS endpoints to the originating UAC before it forwards the final response to the UAC. kind regards, Sigrid Thijs > Rgds, > Manju > > **************************************************************************** > *********** > > This e-mail and attachments contain confidential information > from HUAWEI, which is intended only for the person or entity whose address > is listed above.
