Asterisk 1.4.21.1 (Current branch)
07-09-2008
Asterisk is a hybrid TDM and packet voice PBX (Private Branch eXchange) and IVR platform with ACD functionality. It acts as middleware between the Internet (IAX, SIP, MGCP, Skinny, H.323), telephony channels (like Zaptel, T1, PRI, E1, FXO, FXS, VoIP, VoFR, ISDN, modems, Internet Phone Jack, etc.), and applications (like voice-mail, conferencing, directories, MP3 players, intercoms, etc.). It has many advanced features such as a codec translation API. The base distribution includes several channel backends, as well as applications. However, the beauty of Asterisk is its ability to be extended using its APIs, dynamic module loader, and AGI scripting interface. End users can even write their own applications that run on the system in C or any scripting language of their choice.|

SAFE_ASTERISK(8) Linux Programmer's Manual SAFE_ASTERISK(8) NAME
safe_asterisk -- A wrapper to run the asterisk executable in a loop SYNOPSIS
safe_asterisk [ asterisk_params ] DESCRIPTION
safe_asterisk is a script that runs asterisk in a loop, which can be useful if you fear asterisk may crash. The script does not run in the background like a standard service. Rather, it runs in its own linux virtual console (9, by default). It also uses the option '-c' of asterisk(8) to avoid detaching asterisk from that terminal. safe_asterisk also runs asterisk with unlimited core file size, and thus asterisk will dump core in case of a crash. To get a "picture" of console 9, from another terminal (e.g: from a remote shell session) you can use: screendump 9 The init script of the Debian package should be able to run safe_asterisk as the asterisk service, if so configured. See coments in /etc/default/asterisk FILES
/tmp safe_asterisk runs in that directory, rather than in / as usual. /tmp/core If core files were generated there, they may be /etc/asterisk/startup.d Files in this directory will be 'source'd by the safe_asterisk script before it starts Asterisk proper, allowing them to set addi- tional environment variables or run any other steps that are needed for your system. BUGS
While showing the output on a console is useful, using screen(1) as the terminal may be better. The script does not read configuration from standard location under /etc It uses fixed locations under /tmp , and thus may be exposed to a symlink attacks. SEE ALSO
