Thanks, Brett ---- Should this draft be limited to requests outside of a dialog? More specifi= cally, I'm concerned with the potential of vendors lowering the initial Max= -Forwards based upon the number of Route entries within dialog. Concerning the following section 5 quote, the requirement to only decrement= by 1 causes the B2BUA to be uselessly vulnerable to receiving large Max-Fo= rwards values (potential impacts are discussed within RFC 5393). Section 7= 's flexibility to act differently might be good enough to address my concer= n; however it might be good to reiterate that RFC 3261 indicates that the m= aximum is 255 to help protect handling if higher values are received. My p= reference is to always allow a B2BUA to decrement by more than 1 similar to= what a UA can do when selecting the initial value. "All B2BUA types MUST copy the received Max-Forwards header field from the received SIP request on their UAS side, to any request(s) they generate on their UAC side, and decrement the value, as if they were a Proxy following [RFC3261]." Also concerning the above quote, some services should cause the resulting r= equests to not proxy/decrement the Max-Forwards. For instance a received I= NVITE might cause sending NOTIFY and multiple INVITEs. The NOTIFY likely w= ould not use the received/decremented Max-Forwards; similarly generating a = new Max-Forwards for some of the INVITEs may be appropriate if specific ser= vices cause an INVITE to be sent after receiving an INVITE. Concerning the following section 5 quote, RFC 3261 does not require the req= uest to be rejected. For instance, it specifically allows the OPTIONS to b= e acknowledged with a 200 response. "Being a UAS, B2BUAs MUST also check the received Max-Forwards header field and reject the request if the value is zero, as defined in [RFC3261]." Concerning the following section 5 quote, it should be updated to indicate = "which SHOULD be 70". This would better reflect RFC 3261 section 16.6 with= out introducing ambiguity with prior MUST. "If the received request did not contain a Max-Forwards header field, one MUST be created in any requests generated in the UAC side with a default value of 70, as described for Proxies in section 16.6 part 3 of [RFC3261]."

B2BUAs in a singling path always have the ability to muck with SDP, that's part of the problem with them.

Thanks, Brett ---- Section 3: I agree that it would be useful to add the additional B2BUA role= type (such as "SDP-aware B2BUA") which modify SDP but is otherwise not a m= edia-plain B2BUA. Section 3.1.1: If the Proxy-B2BUA sends UPDATE, it corrupts the cseq space.= Thus, it will subsequently need to continue to modify the cseq values to = avoid potential cseq related issues. Since such a B2BUA impacts cseq space= , RFC 4028 functionality, and other things, they potentially should fall in= to the Signaling-only role type.

Curre= ntly, the only proposal on the table is Hadriels’s B2BUA taxonomy doc= ument: http://www.ietf.org/id/draft-kaplan-straw-b2bua-taxonomy-00.txt=

 

Next week we intend to ask the working group for adoption of the draft.<= o:p>

However, if someone else is planning to submit a draft on the= same topic, we ask that person to inform the working group when it is expe= cted to be available.

We also intend to organize a phone meeting, where w= e will discuss the B2BUA roles. A doodle poll for the dates will be posted = shortly.
