Re: [Sip-implementors] Query - are *header* parameters (other than tag) of From and To part of dialog state?

2010-02-22 Thread Roman Shpount
You are absolutely correct about RFC 3261. In regard of RFC 2543 the situation is a bit more tricky, since it never properly defines what matching To and From headers is supposed to mean. It does talk about saving complete To and From headers in the dialog state as local and remote addresses, and

The tag is used only by the UAs to indicate support for changed from/to URIs, but for proxies which do not support changed from and To-URI this new RFCs says there are no provisions and says as below "This document makes no provision for proxies that are unable to tolerate a change of URI, since

Section 12.2.1.1 of 3261 talks about how the UAC constructs mid-dialog requests and it concerns itself with how From and To *URI* and tags are set. There's nothing in there suggesting that header parameters MUST or even SHOULD be retained. The part about 2543 compatibility also does not talk a

More info: UAS is Fring wired into our own SIP server. UAC happens to be a CISCO PSTN Gateway. Fring is serving up multiple headers (on separate lines) in a 200 OK response - which we don't see with Linksys, Polycom, XTen, etc. So is there a rule for expressing this: Record-Rout
