additionally FYI,
There are some NGN specifications and activities
(basically relating with IMS) in:
http://www.itu.int/ngnproject/main_table.aspx
Specifications relevant with SIP are :
ITU-T SG11 has Signalling specification :
- Q.3401 (NGN NNI Signalling Profile (Protocol Set 1))
* documents are found in
links in above ITU-T site, or
http://www.itu.int/publications/default.aspx
Q.3401 is in Pre-published Status, there isn't Free PDF Version.
ETSI TISPAN (TISPAN3) has a lot of Signalling specifications :
- RTS/TISPAN-03073-NGN-R2 183 007 0.0.0
(Originating Identification Presentation (OIP) and Originating
Identification Restriction (OIR) ; Protocol specification)
- RTS/TISPAN-03074-NGN-R2 183 008 0.0.3
(Terminating Identification Presentation (TIP) and Terminating
Identification Restriction (TIR); Protocol specifications)
- RES/TISPAN-03092-NGN-R2 (NGN SIP & SDP)
DES/TISPAN-03019-NGN-R1 (NGN SIP & SDP)
- etc.....
