An intermediary (proxy or B2BUA) is challenging the request. > I mean by the word proxy what does the server mean? RFC 3261 section 6 provides the definition of proxy. However if a B2BUA relays requests, it may challenge such requests using a 407 response. RFC 3261 section 22.3 may be helpful. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
