Additional sound files for the Asterisk PBX
Extra sound files for use with the Asterisk PBX, including many city names, phases and words. These sounds were recorded in March of 2003 by Allison Smith, who does PBX voicemail voices for hire and is the voice of Asterisk. She does a great job! Note: she did not, in fact, make the monkey noises. These sounds have been donated to the Asterisk community. Many of these sounds will probably find their way into the Asterisk standard distribution (notably the number enunciations, which are useful for speaking dates.) However, the rest are for general consumption.
More information about apt-get remove
Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library.
apt-get remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. If a plus sign is appended to the package name (with no intervening space), the identified package will be installed instead of removed.
