The Asterisk Development Team has released version 1.2.7.1 of Asterisk. This release contains only two fixes, one of which is that the Page() application was entirely broken in version 1.2.7. If you have already upgraded to 1.2.7 and you do not use the Page() application in your dialplan, there is no need to upgrade to version 1.2.7.1.The release is available on the Digium FTP servers as PGP signed tarballs and also as PGP signed patch files, to ease upgrading from the previous versions. The keys used to sign these files can be verified by using the keyserver at pgp.mit.edu.
