Hi,
This may be more a SIP question than a Kamailio question, but I am trying to figure out why 407 challenges from Kamailio contain To tags.
I suppose I've not run across it before, and I can't find an RFC-based rationale. A negative reply to an invite transaction without an intermediate early dialog-forming reply (e.g. 183 with To tag) does not form a dialog, nor takes place within a context in which a dialog was created. So what gives?
Insights appreciated!
