How to Install Asterisk 11 in RHEL/CentOS/Fedora and Ubuntu/Debian/Linux Mint

Asterisk is an Open Source software PBX (Private Branch Exchange), developed by Mark Specer of Digium. It allows you to make calls to one another which may have connected to other PSTN (Public Switched Telephone Network) and Voice over Internet Protocol (VoIP). Asterisk runs on Linux, BSD, MacOSX and others. Having built-in features like voicemail, conferencing, IVR, queuing etc.
In this article, we are going to see a basic installation and working of Asterisk 11 in RHEL 6.4/6.3/6.2/6.1/6.0, CentOS 6.4/6.3/6.2/6.1/6.0, Fedora 18,17,16, Ubuntu 12.10/12.04/11.10, Linux Mint 14/13 and Debian Linux Operating Systems.

1. Preparation for Installation

First, you make sure that your system is up-to-date, if not try to update the system and then install dependencies packages using “yum command” and “apt-get command“, before installing Asterisk on your system.

On RHEL/CentOS/Fedora

# yum -y update
# yum install -y make wget openssl-devel ncurses-devel newt-devel libxml2-devel kernel-devel gcc gcc-c++ sqlite-devel

Turn Off SELinux by changing the line “enforcing” to “disabled” in /etc/selinux/config file.

SELINUX=disabled

Once you disabled SELinux, you need to reboot the system.

reboot

On Ubuntu / Linux Mint / Debian

# su root
# apt-get update && apt-get upgrade -y && reboot
# apt-get install build-essential wget libssl-dev libncurses5-dev libnewt-dev  libxml2-dev linux-headers-$(uname -r) libsqlite3-dev

2. Downloading DAHDI, LibPRI and Asterisk Tarballs

Download the source tarballs, these following commands will download current release of DAHDI 2.6, LibPRI 1.4 and Asterisk 11.

How to Install Asterisk-GUI

After I try to install asterisk on my previous writings, it seems so hard to configure with CLI. However i’m just a newbie…remember that. So, I’m trying to find an easy way to configure using ‘Asterisk-gui’. actually there are many third-party applications developed for asterisk, such as pbxware, asterisk now, freepbx, briker, etc. asterisk-gui is a web interface, it’s just like you have installing a trixbox on your own.
Here is step by step installation:
1. Go to your installation directory (for example: /usr/src), download the latest version:
[root@gembul ~]# cd /usr/src/
[root@gembul src]# svn checkout http://svn.digium.com/svn/asterisk-gui/trunk asterisk-gui

this is will create directory named asterisk-gui

2. Enter asterisk-gui directory, compile and install:
[root@gembul asterisk-gui]# ./configure
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking for uname... /bin/uname
checking for gcc... gcc
##################################### skipped #####################################
configure: Package configured for:
configure: OS type : linux-gnu
configure: Host CPU : x86_64
[root@gembul asterisk-gui]# make && make install
##################################### skipped #####################################
+------- Asterisk-GUI Build Complete -------+
+ Asterisk-GUI has successfully been built, +
+ and can be installed by running: +
+ +
+ make install +
+-------------------------------------------+
+---- Asterisk GUI Installation Complete ---+
+ +
+ YOU MUST READ THE SECURITY DOCUMENT +
+ +
+ Asterisk-GUI has successfully been +
+ installed. +
+ +
+-------------------------------------------+
+ +
+ BEFORE THE GUI WILL WORK +
+ +
+ Before the GUI will run, you must perform +
+ some modifications to the Asterisk +
+ configuration files in accordance with +
+ the README file. When done, you can +
+ check your changes by doing: +
+ +
+ make checkconfig +
+ +
+-------------------------------------------+
3. Configure general parameters, I suggest to backup your default configuration first. and then modify manager.conf http.conf files:
[root@gembul asterisk]# cp -r /etc/asterisk /etc/asterisk.backup
[root@gembul asterisk]# vi /etc/asterisk/manager.conf
[general]
enabled = yes
webenabled = yes
port = 5038
bindaddr = 0.0.0.0
[gembuls]
secret = your_password
permit=0.0.0.0/0.0.0.0
read = system,call,log,verbose,agent,user,config,dtmf,reporting,cdr,dialplan
write = system,call,agent,user,config,command,reporting,originate
[root@gembul asterisk]# vi /etc/asterisk/http.conf
[general]
enabled = yes
bindaddr = 0.0.0.0
bindport = 8088
prefix = gui
enablestatic = yes
4. Reload/restart your asterisk
[root@gembul asterisk]# asterisk -r

RESET SAMSUNG ML-2240

Samsung ML-2240 setelah counter pagenya menunjukkan angka di atas 1800, maka printer ini akan blink yang disertai dengan berkedipnya lampu merah pada printer. Lampu merah tersebut menunjukkan bahwa toner telah habis. Walaupun toner sudah kita refill, namun lampu merah tersebut tidak bisa hilang.

Hal ini mengakibatkan printer Samsung Ml-2240 ini tidak bisa ngeprint. Agar printer Samsung ML-2240 ini dapat berpungsi kembali, maka kita harus mereset ulang kembali counter page tersebut dengan cara manual menggunakan jumper atau dengan membeli alat chip. Untuk cara reset manual Samsung Ml-2240 menggunakan jumper akan kami jelaskan di sini.
Sebelum kita melakukan reset printer Samsung ML-2240, sebaiknya anda melakukan test printer untuk melihat OS Version dan hasil terakhir Toner Page Count dari printer Samsung ML-2240.


Cara test printer Samsung ML2240:
1. Hidupkan printer, dan tunggu sampai proses kalibrasi selesai
2. Pasang kertas 3 lembar, kemudian tekan tombol Resume selama 3 detik. Lepas tekanan pada tombol resume, dan printer melakukan test print.

3. Setelah selesai test print, perhatikan OS Version dari hasil test printer anda.
Ada beberapa tipe OS Version dari Samsung ML-2240 ini yang tidak dapat kita reset secara manual menggunakan jumper. Adapun tipe OS Version Samsung ML-2240 yang dapat di reset adalah :
1.01.00.68
1.01.00.70
1.01.00.72
1.01.00.76
1.01.00.77
1.01.00.78
semuanya bisa di reset pake jumper atau disolder.
Tapi kalo yang OS versi :
1.01.00.82
1.01.00.83
Masih belum bisa di reset pake jumper.
Langkah-langkah reset printer Samsung ML-2240
A. Peralatan yang dibutuhkan :
- Obeng plus (+), dan obeng minus (-)
- Kabel atau kawat kecil untuk jumper
B. Langkah-langkah reset printer Samsung ML-2240
- Lepas semua kabel printer (kabel power printer dan kabel data printer), dan pastikan switch printer dalam keadaan OFF
- Lepas dua buah baut yang ada pada bagian kiri dan kanan di belakang printer menggunakan obeng plus (+)

- Setelah kedua baut dilepas, dan soket pengunci dibuka, geser cover ke samping secara pelan-pelan.

- Lepas kipas pendingin yang menempel pada cover

- Akan terlihat dua buah mesin printer Samsung ML-2240, yaitu mesin power supply dan motherboard.

- Cari dan perhatikan IC EEPROM kaki 8 yang menempel pada mainboard printer Samsung ML-2240, yaitu ic U6 dengan nomor 93C66WP.

- Setelah IC U6 ditemukan, pasang dan hubungkan jumper atau kawat kecil pada ic kaki 1 dan 4
Kalau terbiasa menggunakan solder, solder aja kabel tersebut pada kaki 1 dan 4 agar anda tidak ribet memegangnya.

- Setelah kaki 1 dan 4 pada ic dihubungkan, pasang kabel power, dan hidupkan printer.
- Tunggu beberapa saat hingga printer selesai kalibrasi dan lampu menunjukkan warna hijau
- Setelah lampu hijau, matikan printer, kemudian lepas kabel atau kawat yang menempel pada kaki 1 dan 4 IC EEPROM 93C66WP
- Tutup kembali cover belakang printer tersebut dan jangan lupa pasang dua buah baut skrup yang dilepas tadi.
Reset Samsung ML-2240 telah selesai dilakukan, dan printer beroperasi kembali.
