What does Asterisk do in Linux? It passes the interpreted version to commands. For example, the most commonly used special character is asterisk, * , meaning “zero or more characters”. When you type a command like ls a* , the shell finds all filenames in the current directory starting with a and passes them to the ls command.
Is Asterisk still used? Today, there are more than one million Asterisk-based communications systems in use, in more than 170 countries. Asterisk is used by almost the entire Fortune 1000 list of customers.
Is FreePBX and Asterisk the same? FreePBX, as per the definition from FreePBX.org, is “a web-based open source GUI (graphical user interface) that controls and manages Asterisk.” So it’s a GUI built on top of Asterisk that makes it easier to deploy a PBX from that Asterisk core.
