    Asterisk installation for linux

    The reference page is http://www.asterisk.org/

    We can download the 1.6.2.20 version and untar it.

    1)

    # tar -zxvf asterisk-1.6.2.20.tar.gz
    # rm -f asterisk-1.6.2.20.tar.gz
    # cd asterisk-1.6.2.20

    2) execute "make"

    And if everything has been correct

    3) execute "make install"

    The first time is recommended to install the examples of Asterisk PBX using the command

    4) "make samples"

    But, caution !! This command will rewrite all the configuration files that you already had

    Then you can start Asterisk PBX with the following command

    # asterisk -vvvc

    You could see a lot of messages at the screen when Asterisk starts. (the "vvv" means "very very verbose") and the "c" letter shows us at the end of all the messages a console command line like the following one.

    *CLI>

    At this point Asterisk is installed and running. The command "help" at the command line is very useful

    You also can use the command "man asterisk" in the linux command line to get information about how to start and stop Asterisk server.

    The Asterisk configuration files have been installed in the /etc/asterisk directory where you can find a lot of information.

    Now we are going to verify that Asterisk is running ok with some easy tests:

    We must configure a softphone, for example SJPhone, (more info about its configuration in Sjphone configuration) to register in our own Asterisk server. The default installation has two user that we can use.

    A: user: 3000 password=anything works
    B: user: 3001 password=anything works

    When we have it properly configured and the user has been registered in our Asterisk server it is time to make some calls defined in the default extension dialplan.

    1000 - Main menu
    1234 - Transfer the call to the console (you could see the call at the console command line)
    1235 - Console voicemail
    1236 - Call to the console command line

    3000 - Call to 3000 SIP user
    3001 - Call to 3001 SIP user

    500 - Call to Digium

    600 - Echo test

    8500 - Voicemail menu

    99990 AGI test
    99991 EAGI test
    99992 Tell the hour
    99999 Music

    700 Parked call
    701-720 Parking calls

    One interesting tests at this moment is to configure 2 softphones in two different computers: one with the 3000 user and the other one with the 3001 user and make a call each other. If it works you are ready to learn how to configure Asterisk and create new users and dialplans in the first steps with Asterisk chapter.
