Cara instalasi dan mempergunakan trixbox

Trixbox adalah sebuah VoIP server yang dibundel menjadi

satu dengan system operasi, yaitu Linux CentOS. Trixbox

bersifat open source, artinya setiap orang dapat mengetahui

source code programnya dan memperolehnya secara gratis.

Trixbox terdiri dari komponen-komponen sebagai berikut:

1. Sistem operasi   : CentOS Linux

2. Database    : MySQL

3. VoIP server      : Asterisk

4. Tampilan GUI    : FreePBX

Trixbox dapat diinstal di komputer PC biasa, tidak harus

computer server. Untuk PC biasa, kebutuhan minimal untuk

dapat menginstal Trixbox sebagai berikut:

1. Pentium II 350 MHz

2. Memory 256 MB

3. Harddisk dengan ruang minimal 4 GB

4. LAN card 10/100 Mbps

5. CD-ROM

Pada percobaan kali ini, saya mempergunakan :

[i].   1 Buah komputer untuk Server Trixbox

[ii].  1 Buah komputer untuk client (softphone)

[iii]. 1 Buah IP-Phone D-link (GLV-515)

[iv].  1 Buah Switch 10/100 Mbps

[v].   Kabel Utp secukupnya

--------------------------------------------------

Langkah-langkah menginstall trixbox, yaitu :

--------------------------------------------------

[a]. Siapkan CD instalasi Trixbox

[b]. Pastikan bahwa setting pada BIOS akan mem-boot

 CD-ROM pertama kali, ubah terlebih dahulu jika

 setting BIOS belum benar

[c]. Masukkan CD Trixbox dan restart komputer.

 Tunggu hingga muncul tampilan berikut

[1].

--------------------------------------------------

--------------------------------------------------

[2]. Selanjutnya ikuti perintah yang muncul ^_^...

 Pemilihan Keyboard Type

--------------------------------------------------

--------------------------------------------------

[3]. Pemilihan Time Zone

--------------------------------------------------

--------------------------------------------------

[4]. Pengisian root password

--------------------------------------------------

--------------------------------------------------

[5]. Memulai Proses Instalasi

--------------------------------------------------

--------------------------------------------------

[6].

--------------------------------------------------

--------------------------------------------------

[7]. Menginstall bootloader

--------------------------------------------------

--------------------------------------------------

[8]. Booting Trixbox

--------------------------------------------------

--------------------------------------------------

[9]. Pengisian user dan password login. mode CLI

--------------------------------------------------

--------------------------------------------------

[10].

--> untuk pertolongan ketikan help-trixbox

--> lalu untuk mengkonfigurasi ethernet interface,

 ketikan system-config-network

--------------------------------------------------

--------------------------------------------------

[11]. Edit Devices

--------------------------------------------------

--------------------------------------------------

[12]. Pilih interface yang akan dipergunakan

--------------------------------------------------

--------------------------------------------------

[13]. Pilih ingin static IP atau DHCP

--------------------------------------------------

--------------------------------------------------

[14].Karena di lab menggunkan DHCP, maka saya me-request

 ip dari DHCP Server, IP yang didapat adalah

 10.14.200.17/24

--------------------------------------------------

--------------------------------------------------

[15].Untuk mempermudah konfigurasi, kita akan memakai

 bantuan GUI, buka browser dari komputer lain, ketikan

 https://10.14.200.17, rubah dari mode user ke

 mode admin

--------------------------------------------------

--------------------------------------------------

[16].Jika muncul permintaan user dan password, isi dengan

 user=maint dan password=password, untuk merubah

 password maint, di cli server ketikan passwd-maint

--------------------------------------------------

--------------------------------------------------

[17].

--------------------------------------------------

--------------------------------------------------

[18].Pilih PBX Settings

--------------------------------------------------

--------------------------------------------------

[19].Pilih Extensions,Add extension, Device:Generic

 SIP device, Submit

--------------------------------------------------

--------------------------------------------------

[20].Example:

 User Extension : 2003

 Display Name   : harry

 secret         : xxxx

--------------------------------------------------

--------------------------------------------------

[21].

--------------------------------------------------

--------------------------------------------------

[22]. Submit dan Apply Configuration Changes

--------------------------------------------------

--------------------------------------------------

[23]. Continue with Reload, sampai posisi ini konfigurasi

 sederhana server trixbox selesai.

--------------------------------------------------

--------------------------------------------------

[24]. Untuk Client kita menggunakan 1 buah soft-phone

 (x-lite) dan 1 biah IP-Phone GLV-515 (D-Link)

--------------------------------------------------

--------------------------------------------------

[25]. Pada X-lite, klik kanan, Sip account settings

 Add

--------------------------------------------------

--------------------------------------------------

[26]. di Account isikan:

 example :

 Display name : harry

 User name : 2003

 password : xxxx

 dll...

--------------------------------------------------

--------------------------------------------------

[27].Jika tidak ada masalah maka di x-lite akan muncul

 tulisan Ready, "Your username is 2003"

--------------------------------------------------

 --------------------------------------------------

[28].Ip phone yang digunakan adalah produk D-link

 (GLV-515), Bentuk fisiknya adalah seperti berikut:

--------------------------------------------------

a.

b.

c.

d.

--------------------------------------------------

[29].Di Ip-phone parameter minimal yang diisi adalah

 sebagai berikut:

--------------------------------------------------

 --------------------------------------------------

[30]. Untuk pengujian, softphone (x-lite) dengan user

 2003, akan menghubungi Ip-phone GLV-515 dengan

 user 2000, berikut merupakan screenshoot di Ip-

 phone ketika dihubungi oleh user 2003 (harry)

--------------------------------------------------

 --------------------------------------------------

Sekian dan mudah-mudahan dapat bermanfaat..
