Installing Asterisk Dependencies

The accompanying content will download the MP3 sources which are needed to fabricate the MP3 module and use MP3 documents on Asterisk: 

sudo contrib/scripts/

Utilize the install_prereq content to determine the entirety of the conditions on your Ubuntu framework: 

sudo contrib/scripts/install_prereq install

We have just downloaded the MP3 source documents and now we need to advise Asterisk to construct the MP3 module by choosing format_mp3: 

Whenever you are done, press F12 to save and exit, or change to the Save and Exit catch and press Enter. 

Presently we can begin the accumulation cycle utilizing the make order:

Since we have Asterisk introduced we need to introduce the example design records. 

Introduce either the conventional arrangement records with reference documentation by composing: 

sudo make samples

Or then again introduce the fundamental PBX arrangement records: 

sudo make basic-pbx

The last advance is to introduce the Asterisk init content by composing: 

sudo make config

It is likewise a smart thought to run ldconfig to refresh the shared libraries store: 

sudo ldconfig

Creating Asterisk User

Naturally Asterisk runs as a root client. For security reasons we will make another framework client and design Asterisk to run as the recently made client. 

To make another framework client named reference mark run the accompanying order: 

sudo adduser --system --group --home /var/lib/asterisk --no-create-home --gecos "Asterisk PBX" asterisk

To design Asterisk to run as mark client, open the/and so on/default/reference bullet record and uncomment the accompanying two lines: 



Add the indicator client to the dialout and sound gatherings: 

sudo usermod -a -G dialout,audio asterisk

sudo chown -R asterisk: /var/{lib,log,run,spool}/asterisk /usr/lib/asterisk /etc/asterisk
sudo chmod -R 750 /var/{lib,log,run,spool}/asterisk /usr/lib/asterisk /etc/asterisk

Starting Asterisk

Since we are good to go up, we can begin the Asterisk administration with the accompanying order: 

sudo systemctl start asterisk

To check that Asterisk is running, associate with the Asterisk order line interface (CLI) by composing: 

sudo asterisk -vvvr
