Installing Asterisk on Ubuntu Server

I will give an example of a quick installation of Asterisk on Ubuntu Server.
I will install it on versions 14.04 LTS and 16.04 LTS.

First, check if there are updates for the system and install them:

sudo apt-get update
sudo apt-get upgrade

Perform the Asterisk installation:

sudo apt-get install asterisk

Install additional components:

sudo apt-get install dahdi asterisk-dahdi asterisk-mp3 asterisk-mysql asterisk-core-sounds-ru asterisk-core-sounds-ru-g722 asterisk-core-sounds-ru-gsm asterisk-dev asterisk-core-sounds-ru-wav lame

You can see whether Asterisk and its version are running with the commands:

ps aux | grep asterisk
sudo netstat -tap | grep asterisk
sudo netstat -na | grep 5060
sudo netstat -na | grep :5060 | wc -l
asterisk -V

Connect to the Asterisk console using the command:

sudo asterisk -rvv

This is where Asterisk installation is complete, since we didn’t set up unnecessary web interfaces for management, and for advanced users and tweaking they are not needed, all settings must be made in the configuration files located in the /etc/asterisk/ directory.

In the sip.conf file in the “general” block, we will change the specified parameters for security reasons:


And restart asterisk:

sudo service asterisk restart

In case of problems, you can analyze incoming packets, for example, via tcpdump:

tcpdump -i any -vnn -s0 port 5060
tcpdump -i any -vnn -s0 port 5060 and net
