Hi SG16/WP2/Q13 Participants:

The following paper is presented detailing a possible architecture for Gatekeeper-to-Gatekeeper communication. An Ad-Hoc meeting took place on Room-III at 8:30 AM on the Jan 29 Geneva ITU Meeting. I will compile a list of requirements brought up in that meeting soon.

Please note that we present this document to provide some overview and possible solutions to the problems. This is in not way or form the only way to solve the problems, it is only one of the possible solutions.

We solicit your input about: ======================= 1. Requirements 2. Which of the requirements are for H.323v3 work, and which are for further study 3. Required services and Goals 4. Open Issues

Points that were raised in the meeting: ================================

1. Build networks that scale to the Internet 2. allow for both flat, tree and network models 3. provide a method for a gatekeeper to find an Entity that is registered with another gatekeeper 4. Support call-record logging, accounting, and possibly billing (probably as liaison to appropriate working parties)

Thank you for your time,,
