[Sipping] Notes from TISPAN meeting

[Cullen Jennings <[e-mail]>]

Agenda:

Martin presentation
Miguel Presentation
Next Steps

----------

Call Rejection
TISPAN does not need the override call rejection

Jonathan wrote draft with new status code to reject anonymous calls. Seemed
to have good support that it would be acceptable in sipping and that it
would mean TISPAN needs.

-----------

Terminating Party Identification

Need to document more on what is needed here.

Should read draft-rosenberg-sip-identity-privacy-00 it may solve the problem
of call in 800 number, get an operator, and be able to call back that
operator and still protect privacy of operator.

------------

Call Waiting

We don't get the requirement. We think we might be able to do some of them
but not sure. Please help us understand.

------------

Call Diversion

Going with the draft-jennings-sip-voicemail-uri-04 draft

---------------

CPC/OLI

Rocky will write draft for sipping to address trying to solve this with SAML
assertions. 

---------------

Malicious Communication Identifier

Once again, read draft-rosenberg-sip-identity-privacy-00.

The logging system can make the tunneled query

-----------------

Advice of Charge 

Have a look at the app interaction framework.
draft-ietf-sipping-app-interaction-framework-05.txt

-------------------

Call Completion of Busy Subscriber

Clearly related to presence. Jonathan thought that Dialog Package could do
it but is lacking queuing. This is probably hard.

We need to ask about if this needs to work when we have multiple devices for
each user on each side. Also multimedia makes it harder. What sort of queing
is needed

We have rated this a five question marks on the spicy scale

---------------------

How do we respond to this to TISPAN.
1) Jon proposed a tracker
This is a 3 column html table that has some entries in it

2) Eric & Martin will write a communicate in the from of an internet draft

-------------------------

Moving on to Miguel slide sets. This is not in requirements draft but came
up recently. It had to do with opening and closing media gates based on what
is happening in signaling. Related to one way media. Clearly we need to more
requirements for this.
