Asterisk on centos (deprecated)

this guide was gathered from official asteriks wiki (https://wiki.asterisk.org/wiki/display/AST/Asterisk+Packages#AsteriskPackages-YUM(CentOS6/RedHatEnterpriseLinux6))

first of all install libsrtp and libsrtp-devel

yum install libsrtp libsrtp-devel

Adding the repository

rpm -Uvh http://packages.asterisk.org/centos/6/current/i386/RPMS/asterisknow-version-3.0.0-1_centos6.noarch.rpm
yum update

install

yum install asterisk asterisk-configs --enablerepo=asterisk-11

install dahdi

yum install dahdi-linux dahdi-tools libpri

again upgrade

yum update

Basic configure add ser accounts into the /etc/asterisk/sip.conf

[user1]
type=friend
host=dynamic
secret=verysecretpassword ; put a strong, unique password here instead
context=users
;deny=0.0.0.0/0
;permit=192.168.5.0/255.255.255.0 ; replace with your network settings
 
[user2]
type=friend
host=dynamic
secret=othersecretpassword ; put a strong, unique password here instead
context=users
;deny=0.0.0.0/0
;permit=192.168.5.0/255.255.255.0 ; replace with your network settings

We have commented deny/permit lines with ";" character coz we would like to allow users to access server from anywhere. BUT! Asterisks wiki told us:

Be Serious About Account Security We can't stress enough how important it is for you to pick a strong password for all accounts on Asterisk, and to only allow access from trusted networks. Unfortunately, we've found many instances of people exposing their Asterisk to the internet at large with easily-guessable passwords, or no passwords at all. You could be at risk of toll fraud, scams, and other malicious behavior. For more information on Asterisk security and how you can protect yourself, check out http://www.asterisk.org/security/webinar/. (c)https://wiki.asterisk.org/wiki/display/AST/Creating+SIP+Accounts

go to the Asterisk command-line interface. with simple command

asterisk

make sip reload with netx command:

sip reload

Create Dialplan Extensions. add these lines into /etc/asterisk/extensions.conf

[users]
exten=>6001,1,Dial(SIP/user1,20)
exten=>6002,1,Dial(SIP/user2,20)

The extension numbered 6001 which attempts to ring user1 phone for twenty seconds, and an extension 6002 which attempts to rings user2 phone for twenty seconds.

make dialplan reload in the Asterisk command line interface

 dialplan reload

You can verify that Asterisk successfully read the configuration file by typing dialplan show users at the CLI.

dialplan show users

You can now try to make test call using for example ExpressTalk software for windows (http://www.nch.com.au/talk/index.html)
