cd /usr/src sudo wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-18-current.tar.gz sudo tar xvf asterisk-18-current.tar.gz

Change into the extracted directory and install additional required packages:

Now, proceed to compile and install Asterisk:

sudo ./configure sudo make menuselect sudo make sudo make install sudo make samples sudo make config sudo ldconfig

sudo systemctl start asterisk sudo systemctl enable asterisk

Ensure that Asterisk is running without issues:

sudo asterisk -vvvr
