“Due to the easy of implementation Asterisk has become
more popular than anything else. Asterisk is very easy to use and
lots of open source and closed source panels provide a GUI for it.“Installation of asterisk server:
Pre-requites for asterisk installation: Asterisk requires a system
running with kernel 2.6 and the header files must be present to
compile asterisk on our system. Asterisk is written in c; we
require gcc with the supporting libs such as termcap, and openssl.
Asterisk add-ons require the mysql header files so please install
mysql lib, mysql client and the headers to compile
asterisk-addons.”
