Hi All

I intend to submit = the attached Internet draft to IETF.  This draft is based on the = 3gpp contribution S1-090067 to 22.173 (latest one) that talks about = dynamic blocking of incoming communications.

Abstract:  This = I-D extends the SIP Reason header defined in RFC 3326 to allow = terminating users (Caller        d = users) to dynamically block the callers from further calling. The = extended SIP Reason header suggests a new protocol value = "block" with options for blocking the callers either = permanently or for a temporary period

Permanent = block:  Reason: block; cause=3D1; = text=3D"Telemarketer";Till=3D0
Temporary = block:   Reason:block; cause=3D2; = text=3D"OOO";Till=3D01032009"09:00:00   - = Implies till when the block should be effective.

This reason header = can be appended to either CANCEL or BYE methods (as mentioned in RFC = 3326) for blocking caller either during alerting or terminating phases = of SIP.

Comments = welcome

Just a quick question: "the called user (UAS) can block the incoming caller (UAC) during ringing phase by looking at the number displayed on the phone" "Looking at Caller ID, the called user decides to block the calling user from further calling" What are you actually blocking? What if the called party is presenting a forged Caller ID? Please take a look at [1].

If the calling party is presenting forged identity then the called user = relies on the proxy server to fetch the correct identity and do the = blocking. So whenever a BYE or a CANCEL request is triggered from the = called user, the server needs to check the identity before adding the = identity to the black list for the called user. This way even though the identity of the calling user is unknown or = forged, it can still be blocked. Should I add all these details to the draft?

It should be made clear=20 that either (1) blocking of caller IDs is only allowed on=20 verified caller IDs - but this approach only helps if all=20 non-verified caller IDs are blocked by default, otherwise=20 spitters would just make sure their IDs cannot be verified,=20 or (2) the system is susceptible to indirect blacklisting=20 attacks, i.e. an attacker can use a victim's caller ID and=20 misbehave to get the victim blocked from the network. In=20 some cases, this might be considered acceptable, but people=20 should be aware of the effect when chosing this approach.=20 However, as your draft focuses on the "how" rather than=20 the "why" and the architectural and regulatory framework,=20 this discussion should rather go into a framework document.=20 But what should be discussed in the "reason-header" draft=20 is the question of "when" to apply reason headers. Some=20 people argued that it is counter-productive to send reason=20 headers to spitters because that only helps them increase=20 their efficiency. Your example (Sec. 3.2) allows spitters=20 to schedule retries instead of having retrying effort or=20 just giving up.=20 In addition, the example of Sec. 3.2 is not considered=20 state of the art in security - most people agree you should=20 not leave absence notes like this because these notes give=20 important hints for social engineering.=20 One last remark: if you include a reason such as "Telemarketer"=20 in a signalling message, this should be accompanied by a complaint=20 address giving a hint to a blocked caller how to release the=20 blocking in case the reason is considered incorrect.=20 An exception from this would be if telemarketers were obliged=20 (e.g. by law) to signal the nature of their call in the INVITE=20 message and it was understood in the network that callees can=20 opt out of telemarketing calls (potentially paying more for their=20 phone service in return). In that case, it might be clear to the=20 caller that the reason code relates to their initial call-intent=20 code...

If the calling party is presenting forged identity then the called user = relies on the proxy server to fetch the correct identity and do the = blocking. So whenever a BYE or a CANCEL request is triggered from the = called user, the server needs to check the identity before adding the = identity to the black list for the called user. This way even though the identity of the calling user is unknown or = forged, it can still be blocked. Should I add all these details to the draft?
