Question about H.248 Annex F
by Sasha Ruditsky 07 Oct '05

07 Oct '05

Hi In version 3 of H.248.1 the new Annex F was introduced which clarifies ServiceChange procedures. Is this annex is expected to affect versions 1 and 2 of H.248, i.e. for example it is going to become part of implementors guide for those versions? If the answer is no then what is the expected behavior of the version 1 and 2 H.248 entities relevant to the procedures described in Annex F. Thanks, Sasha

Every participant should use the registration form at: http://ftp3.itu.int/av-arch/avc-site/2005-2008/0511_Gen/0511-WP2-16-Regist ration_form.doc. AND advise (cc.) the Rapporteur (patrick.luthi(a)tandberg.no) of your attendance by e-mail. Early registration of your attendance is welcome and encouraged, but preferably before 18 November 2005 to facilitate the production of badges for all participants. People needing visa support letters (see below for requirements) should register as soon as possible. We would remind you that citizens of some countries are required to obtain a visa in order to enter and spend time in Switzerland. The visa must be requested and obtained from the office (embassy or consulate) representing Switzerland in your country or, if there is no such office in your country, from the one that is closest to the country of departure. If problems are encountered, for ITU members, the ITU can, at the official request of the administration or company you represent, approach the competent Swiss authorities in order to facilitate delivery of the visa. Visa requests should be made by official letter from the administration or company you represent. This letter must specify your name and function, date of birth, passport number as well as the date of issue and expiration. The letter must be accompanied by a photocopy of your passport and completed registration form and must be sent to TSB, bearing the words "visa request", by fax (No.: +41 22 730 5853) or e-mail (tsbreg(a)itu.int) Please note that the Union needs at least one week to process all papers required for the delivery of a visa. For the ones needing this letter, TSB should receive a meeting registration form which can be found at: http://ftp3.itu.int/av-arch/avc-site/2005-2008/0511_Gen/0511-WP2-16-Regist ration_form.doc. 7. Hotel Room Reservation ^^^^^^^^^^^^^^^^^^^^^^^^^ Participants should contact the hotels directly for finding your room availability and making room bookings. Hotels offering preferential room rates for ITU participants are found at: http://www.itu.int/travel/index.html. An appropriate hotel reservation form can be found at: http://ftp3.itu.int/av-arch/avc-site/2005-2008/0511_Gen/0511-WP2-16-Hotel- reservation-form.doc. Please note that participants must use this hotel reservation form, or they would NOT get the special ITU rates. Note: the closest business-class hotel to the ITU buildings is the Intercontinental, and a more popular strategy is to obtain hotel accommodations downtown, e.g., near the Cornavin train & bus station (which is more centrally located than the ITU or the Intercontinental), from which buses run frequently to the vicinity of the ITU. Not all hotels are equipped with high-speed internet access, so participants may want to check with the hotel for the availability of this service. I am looking forward to meeting with you in Geneva. Sincerely yours, Patrick Luthi ---------- ** CRM114 Whitelisted by: simao.campos(a)itu.int ** [View Less]

Dear colleagues, can someone help this engineer from Brazil? I will translate his two questions: 1) When RRq fails in H.225.0 and there is a retransmission, requestSeqNum is repeated. His question is, what does he use as the timestamp? I presume it remains the same. 2) What happens with the timestamp when summer savings time (clock is adjusted one hour ahead or behind) starts? I presume if it changes outside a session, it is business as usual; if it changes in the middle of a session, then … [View More]
