[asterisk-dev] Asterisk Core Sounds 1.4.15, Extra Sounds 1.4.8, and Freeplay MoH Update Released

[Asterisk Development Team]

The Asterisk development team is pleased to announce the release of Asterisk
Core Sounds version 1.4.15, Extra Sounds 1.4.8, and Freeplay Music On Hold
sound files. These sound files are available at
http://downloads.digium.com/pub/telephony/sounds/. Future versions of
Asterisk will do this automatically from the Makefile (when the sounds are
enabled in menuselect).

Jean-Marc Valin (from Octastic) had been experimenting with high-pass filters
on the existing Asterisk sound files and found a configuration which
dramatically reduced the amount of low-frequency sound on the prompts, thereby
making them sound much clearer, especially when used with highly compressed
codecs such as GSM and G.729. The existing sound files have been run through
this filter and released back to the community.

If you do not wish to upgrade your version of Asterisk, you can still install
the sound prompts manually.

First, download the sound files with wget for all the sound formats you need.
Our example below is downloading the core sounds for the english language in
the wav format:

# mkdir /usr/src/asterisk-sounds
# cd /usr/src/asterisk-sounds
# wget 
http://downloads.digium.com/pub/telephony/sounds/asterisk-core-sounds-en-wav-current.tar.gz

Then extract the files into your sound directory. By default in Asterisk 1.2
and 1.4, the files are located in /var/lib/asterisk/sounds/ and in Asterisk
1.6.x they are located in /var/lib/asterisk/sounds/_language_/ where _language_
should be replaced with 'en' for english, 'fr' for french, 'es' for spanish,
etc.

# cd /var/lib/asterisk/sounds/en/
# tar zxvf /usr/src/asterisk-prompts/asterisk-core-sounds-en-wav-current.tar.gz

Then do the same for the Extra sounds. For music on hold, perform a similar
process, but the music on hold sounds are located in /var/lib/asterisk/moh/.

Thank you for your continued support of Asterisk!
