Re: [Sip-implementors] DoS protection and amplification

[Anders Kristensen]

Incidentally, the spec doesn't say but presumably this recommendation applies only to INVITEs? (As final responses to non-INVITEs are retransmitted only on receipt of request retransmission.)

Hi

Section 26.3.2.4 of RFC 3261 on DoS Protection
recommends that proxy servers should forgo
response retransmission for 401 and 407
responses. Should this apply in general to
any response that is generated before the
credentials of the caller can be verified
say 403 responses? Was there a reason for
limiting this recommendation to 401 and
407 responses?
