Miguel,

Yes, as soon as I saw that we were considering using P-Charge-Info I  
went looking around to see if it had been registered with IANA (it  
wasn't) and looking at what *was* registered with IANA.  I did see  
RFC 3455 (and indeed reference it in my draft) and looked at P- 
Charging-Vector. However, P-Charging-Vector is more complicated than  
we need.  Undoubtedly P-Charging-Vector works well within the larger  
context of 3GPP, but all we want to do is provide a single billing  
identifier to the upstream proxies.

What I am really aiming to do with this draft is register an already  
existing practice of using the P-Charge-Info P-Header with IANA, as  
is required under RFC 3427 (section 4.1).  Sonus Networks is using  
this in their switches and has mentioned it to carriers using their  
gear.  One of those carriers, who we work with, suggested it as a way  
to solve our billing issues.  We're now using it and it's working  
fine.  There are now other carriers with whom we are seeking to solve  
the same issue and we will probably wind up using the same  
solution.    We can obviously just continue to do this in the private  
SIP communication between ourselves and the carriers without pursuing  
IANA registration, but, being a "standards guy" I would like to "do  
the right thing" per RFC 3427 and document/register current usage.  I  
would also, frankly, like a document out there to which we can point  
when we talk to yet another carrier saying "here's one way of dealing  
with billing issues, is that applicable to your network?"

Hannes, thanks for the links. Again, though, all we are doing is  
passing along a simple billing identifier.

The -01 draft that I'll get in for Monday will include that  
information. (And someone from Sonus Networks has also agreed to co- 
author.)

Regards,
Dan
