Hi:

I have just submitted a new version of the 3GPP SIP P- headers draft.
I guess it will appear tomorrow in the usual places. In the meantime, you can obtain a copy from:
http://standards.ericsson.net/sip/drafts/draft-garcia-sipping-3gpp-p-headers-01.txt

The HTML version is available at:
http://standards.ericsson.net/sip/drafts/draft-garcia-sipping-3gpp-p-headers-01.html

I believe the document is ready to request its publication as informational RFC.

These are the changes with respect the previous version:

- Clarified that if the registrar supports the P-Associated-URI header, then it MUST always returns it in the 200 OK for a REGISTER, even when the header is empty.

- Made the terminology consistency. Extensive usage of the term address-of-record in the description of the P-Called-Party-ID header.

- Added some discussion text about the uniqueness of the P-Visited-Network-ID. It is suggested to select the   identifier from the DNS domain name.

- Consistent use of terminology in the P-Access-Network-Info header: describing a SIP proxy providing services to the user, independently of whether the proxy is located in the home network or not.

- Clarified that the UA can insert the P-Access-Network-Info header in both requests and responses.

- The P-Charging-Function-Addresses and P-Charging-Vector are described now in different sections.
  
- Removed references to B2BUA in the procedures of the charging headers. Replaced by UA instead.

- The P-Charging-Function-Addresses header syntax now contains a simpler structure, with parameters "ccf" and "ecf" allowing repetition for redundancy purposes.

- The P-Charging-Vector header syntax now mandates the presence of the icid parameter. The icid parameter is split into a value and the host name or IP address of the node that generated the id.

- Removed references to the P-Service-Route in the IANA considerations section.
