Bob,

Thanks for the reference.

from http://microtronix.ca/sip_vs_h323.htm   I Found:

<Quote>
H323
The initial intent of H.323 was for the support of LANs, so it was not 
inherently designed for wide area addressing. The concept of a zone was 
added to accommodate wide area addressing.  Procedures are defined for 
"user location" across zones for email names. Annex G defines communication 
between administrative domains, describing methods to allow for address 
resolution, access authorization and usage reporting between administrative 
domains. In multi-domain searches, there is no easy way to perform loop 
detection. Performing the loop detection can be done (using the PathValue 
field), but introduces other issues related to scalability.

SIP
SIP inherently supports wide area addressing. When multiple servers are 
involved in setting up a call, SIP uses a loop detection algorithm similar 
to the one used in BGP, which can be done in a stateless manner, thus 
avoiding scalability issues. The SIP Registrar and redirect servers were 
designed to support user location

ITU had no response to this. I would then request .....
         o Why not just back-off and leave IETF to do Internet Engineering 
work?
         o Why not leave the scalable NROs to manage IP resources?

We in the developing world are getting wiser, when it comes to 
technological evaluation and acquisition. We work, exclusive of your club 
members - our (deaf and dumb) governments. Need I say more?

SF.
