What I found most irregular was your specific attribution of the document in question to Nortel Networks. It is not that we are ashamed of the document, but that your naming of Nortel Networks in the process of your commentary seemed calculated to affect the attitude of other parties present in Q.13/16 toward Nortel. I have not observed such behaviour in other delegates, and believe that it is incompatible with a chairman's role.

Dear Tom: Allow me to repeat the comments I made during the meeting. I noted that a large contribution comparing SIP and H.323 had been submitted to 3GPP, having the conclusion of SIP's superiority. I complained that I was disappointed in the non-technical nature of much of the material provided, and urged the delegates to bring in real technical contributions concerning the possible demerits of H.323, with a view to the improvement thereof. My goal, then, as now, is the improvement of H.323, and also to call the delegates attention to a document whose existance they may not have been aware of, and which might stimulate them to bring in additional contributions. Any implication that, for example, 3GPP members are gullible, or there were no other contributions in 3GPP on this topic appears to be speculation. In addition, the idea that I or Sonus might profit in some fashion from these comments is both speculative and humorous. As you can clearly see, they have brought me nothing but trouble so far. I am still hoping for the real gain of additional valuable H.323 related contributions. I would like to take this opportunity to thank Francois Audet for his many contributions to H.323 over the years, both as an editor and as a contributor, and also to his many contributions to the ATM Forum. Francois has been, without fail, a positive and helpful member of Q13 and the H.323 community, and I would like to thank Nortel for supporting his standards work. One of the criticisms of H.323 in the 3GPP discussions appeared to be the idea that SIP would be easier to modify for the wireless environment than H.323, apparently because of a perception that the SIP community is more open to change. I feel this is completely unfair and untrue. As rapporteur, I have always welcomed new contributors and new ideas into the H.323 system of recommendations, and would like to urge the further consideration of H.323 for wireless/mobile applications by groups other than 3GPP (of course, further consideration by 3GPP is also welcome!). Such groups will find Q13/WP2/SG16 ready and eager to work with them in defining any changes needed for the wireless/mobile environment. I would also like to call attention to the continuing work of Q13 in H.323 Annex H and I. H.323 Annex H (User Service, and Terminal Mobility in H.323) Determination 11/00 Editor J. Sundquist (Nokia) H.323 Annex I (Packet based MM Telephony over Error Prone Channels) Determination 11/00 Editor B. Aronson (Toshiba)

Sincrely, Dale Skran Q13 Rapporteur
