In this tutorial, we will show you how to install Asterisk on Debian 11. For those of you who didn’t know, Asterisk is an open-source framework used for building communications applications including VoIP gateways, and conference servers. Asterisk uses a VoIP protocol that allows you to make a call using the TCP/IP without any cost. Asterisk also supports all currently used protocols such as SIP, IAX2, GSM, G.711, or ISDN.
