Download Asterisk 1.4.1/1.2.16

Asterisk is a comprehensive PBX for the BSD, Linux and Mac OS X platform. The program offers all the functions you can expect from a telephone exchange. It includes options for voicemail, conferencing and call queuing. In addition, support for caller ID services, ADSI, SIP and H.323 is available. For a complete overview of all possibilities, we refer you to this page. The developers have released two new versions with 1.4.1 and 1.2.16 as the version numbers. The announcements look like this:

Version 1.4.1

This release contains a very large number of bug fixes, including a fix for the recently discovered security vulnerability.

It also contains a complete rewrite of the Shared Line Appearance (SLA) support that was first released as part of Asterisk 1.4.0. The new version of this functionality has been tested against a variety of phones and provides much more flexibility and configurability (along with actually working properly in most scenarios, which the original implementation failed to do). Users who are interested in SLA functionality should update to this version and try it out; we welcome bug reports and test reports.

Because of the security vulnerability fix present in this version, all users of Asterisk 1.4 are urged to update as soon as they can schedule it.

Version 1.2.16

This release contains a number of bug fixes, including a fix for a recently discovered security vulnerability. All Asterisk 1.2 users are urged to update to this release as soon as possible.[break] The following two files can be downloaded:
