hi, volker Sorry :), besides the below point to be clarified by you, could you explain another place which forgets to be added in the below email from the the figure "B.3" ?
when UA B finishes applying the policies from PSA and PSB in the order, why does UA B apply policies from PSA and PSB again like the indication from the step 12 to the step 19? if being session description updated, how does UA B know to stop applying PSA and PSB? moreover, why should not the step 16 be "SUBSCRIBE<o''', a'''>" ? thanks a lot cheers isal -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Yuxia Zhang Sent: Friday, September 26, 2008 4:17 PM To: 'Volker Hilt' Cc: [email protected]; [EMAIL PROTECTED] Subject: Re: [Sip] issues on two different session policies in the draft"draft-ietf-sip-session-policy-framework-04" volker, thanks a lot ! Additionally, there are still another places for the figure 3 and figure 4 in the draft needs to be clarified, can you ? As follows, >From the context, whether should they be "policy channel +infoOffer+InfoAnswer" for the step (9) and (10) in the figure 3 and for +infoOffer+the step (12) and (13) in the figure 4 in the draft? I wonder whether it is my fault or other question, such as typo error, other explanation:) cheers isal -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Volker Hilt Sent: Wednesday, September 24, 2008 12:02 AM To: Yuxia Zhang Cc: [email protected]; [EMAIL PROTECTED] Subject: Re: [Sip] issues on two different session policies in the draft"draft-ietf-sip-session-policy-framework-04" Yuxia Zhang wrote: > hi, all > > some issues on two diffrent session policies of draft-ietf-sip-sip > session policy-framework need to be queried. could you help me? thanks. > as follow, > > Producedures in the draft only describe the usage of the > session-specific policy, is right? so as for the session-independent > policy, how does UAC retrieve it? Session-independent policies make use of the config framework (http://tools.ietf.org/html/draft-ietf-sipping-config-framework-15) as described in the draft. > it is only through SUBSCRIBE request and only simple interactive, is > it ?

They are applied in the order described above.
