I'd say no. Section 19.1.1 of RFC 3261 says: " URIs in Contact header fields have different restrictions depending on the context in which the header field appears. One set applies to messages that establish and maintain dialogs (INVITE and its 200 (OK) response). The other applies to registration and redirection messages (REGISTER, its 200 (OK) response, and 3xx class responses to any method)." which I'd take to imply that Contact headers are only valid on those messages. I'm not sure what the value of the Contact header would be, if you did have one - you wouldn't want to send a list of bindings as you do with the 200 response, because you shouldn't be providing that information to unauthenticated users.
