Report of IP-Telecoms Interworking Workshop
(Numbering, Naming, Addressing and Routing)
ITU, Geneva 25-27 January 2000
The International Telecommunication Union sponsored an IP-Telecoms Interworking Workshop focusing on Numbering, Naming, Addressing, and Routing that was held in Geneva from 25-27 January 2000, chaired by Mr. Fred Gaechter, Rapporteur for Question 1/2. Mr. Gary Richenaker prepared this Report.

During the meeting the following agreements were reached:

1) In concept, the definitions currently contained in ITU Draft Recommendation E.191 for Name, Address, Number and End-User were generally agreed to for use during this meeting. (See Attachment 2).

2) There are no interworking issues that need to be resolved within the existing scope of ENUM.

3) ITU-T participants will review the current iteration of ENUM and other related documents and liaise their comments to the ENUM working group and other relevant working groups following the SG2 meeting in March.

4) There was agreement on 14 Issues to be addressed either by the IETF, the ITU, or jointly by the IETF-ITU. The Issues and their disposition are contained in Attachment 1.

At the conclusion of the meeting the following work plan was agreed:

1) Issues unique to a specific forum will be input to that forum from participants at this workshop.

2) The ITU-T will establish a web site for access to the documents distributed at the meeting, and the meeting report.

3) The IETF will establish a mailing list to allow for collaboration with ITU participants.

4) For joint collaboration work, a conference call will be scheduled in April to discuss the progress of the agreed to work items. This conference call between the ITU and IETF management team will follow both the SG2 and IETF meetings in March. Future meetings may be required.

5) ITU collaborators are welcome to participate in IETF activities on an ongoing basis.

6) The various Web and email addresses for follow-up work are listed over the page.

7) The Workshop Agenda is contained in Attachment 3 and the list of participants in Attachment 4.
