Well, there isn't much worth writing about regarding the last meeting. Victor Pascual Avila, Jan Janak, Nils Ohlmeier, Jan Seedorf and me gathered for some food. Some companies/organizations cut back on spendings with regards to Anti-SPIT development/research and thus not too much is happening. No interesting new SPIT case was found (I guess that could be good or bad ;). No consent was found during a discussion on the SPAM score draft. We have contradicting believes on whether this approach makes sense and if ITSPs would trust headers sent by remote/originating SSPs. I also mentioned that the VoIP Security Alliance (VoIPSA.org) needs some more traffic and an overhaul of their good but outdated whitepaper. If you have some time to spare it might be worth contributing. Since IETF 71 I summarized a few issues and uploaded http://www.ietf.org/id/draft-scholz-endpoint-security-00.txt Please post feedback on this to the list or directly to me. I plan on uploading an updated version in time for Hiroshima.

They wouldn't trust those headers. That wasn't my intent when I wrote the spam score draft, though. Rather, my intent was exactly how "X-Spam-Score:" is used in email today: it is generated by your own mailer -- which you trust enough to store your email and send your email on your behalf. Likewise, the SIP spam score header would be generated by your own, well-loved farm of SIP proxies that, as a whole, are your ITSP. This allows the ITSP to do spam scoring on your behalf and you could then configure the last-hop proxy, or your own SIP UA, to accept/reject/redirect incoming calls based on time of day, the spam score, the from: field, or whatever other criteria are interesting. It's *far* down the future before an ITSPs would trust a spam score generated by some other ITSP -- if ever. -d > I also mentioned that the VoIP Security Alliance (VoIPSA.org) > needs some more traffic and an overhaul of their good but > outdated whitepaper.
