Re: carrier codes in draft-rs-trip-gw-03.txt

Within the context of TRIP and PSTN/GSTN gateway location, the idea is to
use the carrier identification codes (CICs) already used in the PSTN/GSTN.
The problem is that each country has its own carrier codes. Thus the need
for a country code. However, since there is already a naming authority for
country codes and within each country a naming authority for carrier codes
(at least those in circuit switched networks), we do not need an IANA
registry for those. The point of the original mail was that if we are using
legacy CICs in the IP world, there should be a consistent way to represent
and handle them.

If these CICs start getting used across the IP Telephony protocols, and new
CICs are needed for IP tel networks and providers, how would you then manage
the CIC namespace? Would the same authorities continue to give out CICs? Or
would IANA manage the IP-specific CICs? I have not thought much about this
and don't really have any strong opinions at this point. Just something to
think about.
