Chapter 10 of RFC 3261 describes the way to process REGISTER requests. There's no description of any screening of the Contact header uri.
It's now very common to compare it with an ACL to disallow URLs that is considered dangerous, like URLs pointing to internal servers in a service provider's network. I also see a case where a proxy on an IPv4 only network might choose not to accept IPv6 contacts. When reading chapter 10, I realize that there's no documented way of refusing a REGISTER because of an invalid Contact - syntax error, policy error or something else. The text seems to describe a process where we store any authenticated valid requests in the location database to perform selection, prioritization and validation when using the result of a lookup. Have I missed something? Is this described somewhere else? regards, /Olle _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
