[asterisk-announce] Asterisk 1.4.0-beta4 Released

[Asterisk Development Team]

The Asterisk Development Team is pleased to announce the release of
Asterisk 1.4.0-beta4.

This release contains a number of updates:

- a bug fix for the ExternalIVR application and addition of 'silence'
sound files to support it
- various SIP interoperability improvements
- memory and dialog leaks in the SIP channel driver
- a fix to music-on-hold random mode that was not really random
- an improvement to app_voicemail to ensure that the message duration is
properly included in email notifications when voicemail messages are
forwarded
- corrected a segfault issue during reload of the PostgreSQL CDR driver
- a change to no longer include a header file that does not exist on
Linux kernel 2.6.18 (and caused a problem on Fedora Core 6)
- logging of dynamic queue member addition and removal in queue_log
- a minor redesign of many CLI commands to be more similar to previous
Asterisk releases
- significant improvements to IMAP storage support for voicemail
- a change to the SIP channel to avoid offering formats (codecs) that
cannot be transcoded due to lack of available transcoders (along with
dynamic activation/deactivation of transcoders)
- support for G.722 16KHz (wideband) audio passthrough, recording and
playback
- support for standard prompts in G.722 format
- many other bug fixes

Some of the changes in this release are behavior modifications from the
last release; please review the UPGRADE.txt file.

This will very likely be the last beta release of Asterisk 1.4 before
the final release, which is targeted for next Friday.

Thanks for supporting Asterisk and Zaptel!
