[much better to split up the question]
>>but I receive it on UDP, should I strip it? I'd leave it, I don't think it matters much, you would strip the top Route anyway (if the top route is you). (unless you had different applications running on UDP and TCP, I don't think it's important) >>What if the port is different? it shouldn't ever be really. But it could be an issue if you have multiple SIP entities listening on different ports. If it came to you on the wrong port, then it's going to break anyway so you could respond with an error response Regards, Attila -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Taisto Qvist XX Sent: 29 April 2009 14:18 To: [email protected] Subject: [Sip-implementors] Clarifying RFC3261/3 regardingroute-preprocessing [On request, splitting my previous question in three more emails...] Greetings fellow SIPers! I've got a few questions regarding how I should interpret a few things in rfc3263, and related text in 3261. =========== Question 2. =========== Route preprocessing says, with regard to stripping the route header: If the first value in the Route header field indicates this proxy, the proxy MUST remove that value from the request. All the other text in Ch. 16.4 regards the Request-URI and ;maddr parameter, so my question is.....Please Define: "indicates this proxy". Do we have the same rules here as when matching the request-uri and maddr? In other words, if I receive a request with Route: <sip:my-ipaddr:5063;transport=TCP> but I receive it on UDP, should I strip it? What if the port is different? I want to do the same checks as for the request-uri, checking port, transport, etc, but the term "indicates this proxy", is a bit to vague for my taste, so I wouldnt mind hearing your views. I'd be very interessted, and thankful for whatever feedback you folks can provide.
