In "draft-ietf-sip-rfc2543bis-05" pag 82 I read: "Any time a proxy server or user agent receives a request, they MAY challenge the initiator of the response to provide assurance of their identity"
Certainly it is valid for Register, Invite, Bye, Cancel and Option. Is it valid for ACk too? Can a proxy require an authentication on a ACK request?
