Hi, 1. Is it correct to assume that a sip proxy will always put record-route headers with sip or sips uri? [Mitko] Yes. The proxy MUST put into Record-Route header only sip or sips uri (see RFC 3261, chapter 16.6, steps 4). Of course the proxy is not mandatory to put any uri into Record-Route header. 2. Before forwarding the message according to the next route header, a proxy must determine whether the next proxy is a strict router. It therefore searches for 'lr' in this route header. What should the proxy do if the next route header has non-sip uri (tel, in, etc.)? Can non-sip uris contain the lr parameter, and would it have the same meaning as in sip or sips uris? Can the proxy skip the search for lr when the uri is non-sip uri (for example if the answer to 1 is yes)? [Mitko] First according above described rule this situation should not happen. If yes the better way would be to suppose that the next proxy is a strict router, becuase the loose router is able to handle the request in old fasioned way too, but the strict router is not able to handle the request according to new RFC 3261.
