PREREQUISITES Now, with all that said, you really don’t need knowledge of all that. Get the book “Asterisk: The Future of Telephony” from asteriskdocs.org, go to chapter 3 and type in each thing they have written. When you get into trouble, go to the Asterisk wiki at voip-info.org. You haven’t done anything that someone else hasn’t already done. If you have, try for a prize.Now, with all that said, you really don’t need knowledge of all that.

Installing Asterisk make samplesmake samples –Installs the sample configuration files in the /etc/asterisk directory make progdocsmake progdocs –Installs the Asterisk program documentation. This uses doxygen to generate the documentation from the source and some areas are documented better than others make configmake config –Configures the Linux system to execute Asterisk automatically on system startup

Commonly Used CLI Options -c – –Console. This allows you to connect to the Asterisk CLI. Example: asterisk -c -v – –Verbosity. This is used to set the amount of output for CLI debugging. Example: asterisk –vc or asterisk -vvvvvvc -r – –Remote. This is used to reconnect remotely to an already running Asterisk process. Example: asterisk -vr
