As posted on blogs.digium.com today: http://blogs.digium.com/2009/08/18/asterisk-music-on-hold-changes/ the Asterisk project has changed providers for Music-On-Hold (MOH) content distributed with/for Asterisk. In addition to the change for future Asterisk releases, we have also opted to rebuild historical releases with the new MOH content, in an effort to eliminate unnecessary distribution of the old MOH content. This means that all Asterisk releases available on downloads.asterisk.org have been rebuilt to include the new Opsound MOH files, and the release branches and tags in the svn.digium.com Subversion repository have also been changed so that any checkouts from those tags/branches will include (or install) the new MOH files as well. Finally, the AsteriskNOW RPMs available on packages.asterisk.org have been rebuilt using the Opsound MOH files. We have tried to make the changes in a relatively convenient and painless way, but if you encounter any issues with these changes please don't hesitate to post on the asterisk-users mailing list or create an issue on issues.asterisk.org. Thanks for using Asterisk!
