Talk:H.323

Proposal for a new article
Please find below a proposal for a new article on H.323. Feel free to contact us regarding any of the changes made. If there are no comments within the next days the edits are considered supported and we will publish the revised article. ITU-T 11:05, 27 February 2008 (UTC)


 * The suggested changes were presumably incorporated into the article. I have deleted the copy that was included here. --Kvng (talk) 15:15, 15 June 2010 (UTC)

Sources (?)
External links moved here per External_links. Though listed as sources, these are External links, and their purpose and value needs to be considered against WP:EL and WP:LINKFARM. SilkTork (talk) 11:26, 10 June 2021 (UTC)


 * @Paulej @SilkTork I think "Sources" is a pretty bad name. I would rename the section "Standards Documents" and keep them, because they are the official references, even so pretty hard to read. (not sure H.246 belongs there, never heard of that one before) GeneVincent55 (talk) 20:06, 11 June 2021 (UTC)
 * H.246 is for interworking H.323 with various other protocols, notably H.320 and the PSTN. H.320 is used for videoconferencing over ISDN.  PSTN includes protocols like ISUP. Paulej (talk) 21:15, 11 June 2021 (UTC)


 * SilkTork, those are links to the standards that compose the H.323 system. Those were placed there by ITU-T staff and handy to have for anyone who wants to read the various standards.  It's pretty typical for Wikipedia articles to point to standards documents. Perhaps what is unusual is the fact there are so many.  IMO, they are useful in the same way that there are links to IETF RFCs.  As an example, see: https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol. Paulej (talk) 17:00, 10 June 2021 (UTC)


 * Paulej - what is the essential difference between the list at and the ITU-T list below? And if there is a difference, why cannot the ITU-T list be added to your list at packetizer? SilkTork (talk) 15:02, 14 June 2021 (UTC)


 * SilkTork, the list here on Wikipedia is a subset of the links on Packetizer. Having it here is convenient for those looking for this list and I don't think duplication of this is a bad thing, especially as Wikipedia aims to be a source for a lot of information. Paulej (talk) 16:23, 14 June 2021 (UTC)


 * This situation is covered in WP:ELMAYBE#3: "A well-chosen link to a directory of websites or organizations. Long lists of links in articles are not acceptable."
 * The link to Packetizer serves as the link to a directory, and avoids us having a long list of links which is not allowed by policy. Wikipedia aims not to be a source itself, but a summary of existing sources. This situation here captures quite nicely Wikipedia's aims in that we would rather have one good link which summarises a long list of links than host the long list of links ourself.
