Hi, Migues,
As I considered, the requirement of overrding ACR service must be there
as a formal requirement. Maybe there are some ways that the called AS to
get enough information to determine that it can or cannot override the
ACR, but there are some cases the simulation service must be overrided,
including the case you listed in the 02a version. It can be like this:
1. The originating network shall be able to take enough calling party's
information to the terminating network to help to override the callee's
ACR service.
2. The terminating network shall be able to override the callee's ACR
simulation service if the caller is authorized to do this based on the
caller's information.

Hi:

I have another working copy of the TISPAN requirements, now version 02e:

http://people.nokia.net/~miguel/drafts/pre/draft-jesske-sipping-tispan-r
equirements-02e.html
http://people.nokia.net/~miguel/drafts/pre/draft-jesske-sipping-tispan-r
equirements-02e.txt

And a diff version with respect 02d:
http://people.nokia.net/~miguel/drafts/pre/draft-jesske-sipping-tispan-r
equirements-02d-to-e.html

The main changes this time are:

- Rewording of the CCBS/CCNR requirements as per our discussion. I have 
added a few definitions and try to reorder them sequentially, so that 
they are a bit easier to understand.
- Clarification that the TIP requirements are for an additional (to the 
asserted) identity.
- Addition of the Communication Waiting requirements

Please feel free to comment, but bear in mind that due to the TISPAN 
meeting next week most of the TISPANers will have limited time to
discuss.

/Miguel
