ABSTRAK

Kebutuhan akan informasi dan komunikasi semakin meningkat akibat

berkembangnya teknologi. Sehingga dibutuhkan media dan sarana komunikasi

yang akurat, cepat, efisien dan hemat biaya. Salah satunya media komunikasi

yang dikembangkan menggunakan jaringan internet yaitu

Voice Over Internet

Protocol

(

VoIP

).VoIP merupakan teknologi yang dapat menggabungkan antara

jaringan telepon dengan komunikasi data.

Pada tugas akhir ini direalisasikan jaringan VoIP dengan server Asterisk

dan aplikasi

softphone

berbasis Android. Komunikasi jaringan menggunakan

koneksi Wi-Fi yang menghubungkan server dan

client (user)

. Antar

client

baik

yang menggunakan laptop yang terinstal

softphone

x-lite atau menggunakan

smartphone

Android yang terinstal

softphone

SIP yang telah dirancang dapat

berkomunikasi suara dalam satu jaringan yang terhubung Wi-Fi

Perancangan jaringan VoIP dan aplikasi

softphone

SIP pada

smartphone

Android berhasil direalisasikan dalam satu jaringan, penyebaran koneksinya

terbatas pada kemampuan router menjangkau wilayah. Aplikasi

softphone

pada

Android hanya dapat digunakan pada server Asterisk yang penggunaannya

disesuaikan dengan kebutuhan server untuk komunikasi suara saja.

ABSTRACT

The need for information and communication are increasing due to the

development of technology. So it takes media and means of communication of

accurate, fast, efficient and cost-effective. One of them developed communication

media that uses the internet is Voice Over Internet Protocol (VoIP). VoIP is a

technology that can combine between telephone networks with data

communications.

In this final project realized VoIP network with an Asterisk server and

Android-based softphone applications. Communications network using Wi-Fi

connection that connects the server and client (user). Between client whether

using a laptop installed x-lite softphone or using a smartphone installed Android

SIP softphone which has been designed to voice communication in one network

are connected Wi-Fi.

Design a VoIP network and SIP softphone application on Android

smartphones successfully realized in the one network, spread of connection is

limited to the ability the router reach the area. Softphone applications on Android

can only be used on the Asterisk server, its use matched with the needs of the

server just for voice communication.

Bab I Pendahuluan 2

Universitas Kristen Maranatha I.2 Identifikasi Masalah

Diperlukan suatu aplikasi softphone SIP pada smartphone Android yang dapat terintegrasi dengan server Asterisk yang memiliki jaringan VoIP berbasis SIP. Antara client yang telah terinstal aplikasi dapat berkomunikasi satu sama lain tanpa harus menggunakan pulsa atau membayar untuk hubungan tersebut.

I.3 Rumusan Masalah

1. Bagaimana mengkonfigurasi server Asterisk agar dapat digunakan sebagai server VoIP?

2. Bagaimana merancang sebuah jaringan VoIP agar antar client (user) bisa saling berkomunikasi menggunakan server Asterisk?

3. Bagaimana membuat program aplikasi client SIP pada smartphone berbasis Android?

I.4 Tujuan

Tujuan dari tugas akhir ini membuat jaringan server VoIP berbasis SIP dan aplikasi softphone pada smartphone Android untuk dapat menelepon antar client dalam satu server yang terintegrasi.

I.5 Pembatasan Masalah

Dalam perancangan tugas akhir ini, hal-hal yang akan dibahas meliputi: 1. Implementasi VoIP dengan menggunakan client Android.

2. Hanya melakukan perencanaan jaringan VoIP dengan menggunakan software Asterisk sebagai server.

3. Komunikasi antar perangkat hanya melalui hubungan LAN dan Wi-Fi dalam satu jaringan (tanpa dapat komunikasi dengan PSTN atau GSM dan CDMA).

4. Hubungan antara server dan client berbasis Android hanya dihubungkan dengan koneksi Wi-Fi dalam satu jaringan.

5. Tidak membahas yang berhubungan dengan keamanan sistem. 6. Jaringan VoIP menggunakan koneksi wireless Fidelity (Wi-Fi).

Bab I Pendahuluan 3

Universitas Kristen Maranatha I.6 Spesifikasi Alat

Spesifikasi alat yang digunakan untuk perancangan dan realisasi adalah sebagai berikut:

1. Tiga smartphone dengan OS Android, digunakan sebagai client aplikasi Android.

2. Laptop dengan OS Linux Open Suse 10.2 yang terinstal software Asterisk PBX 1.4.17 dan softphone X-Lite, sebagai server dan client pc1.

3. Laptop yang terinstal softphone X-Lite sebagai client pc 2.

4. Wireless Router TP-Link TL-WR841ND, digunakan untuk menyebarkan sinyal Wi-Fi dan pemberi nomor IP.

5. Earphone Genius HS300A yang digunakan untuk komunikasi suara pada client laptop.

I.7 Sistematika Penulisan

Sistematika penulisan laporan dalam tugas akhir ini disusun menjadi beberapa bab seperti yang diuraikan berikut:

BAB I PENDAHULUAN

Dalam bab ini menjelaskan permasalahan yang melatarbelakangi penulisan laporan tugas akhir ini, selain itu membahas identifikasi masalah, rumusan masalah, tujuan, pembatasan masalah dan menguraikan sistematika penulisan tugas akhir ini.

BAB II DASAR TEORI

Dalam bab ini akan dibahas mengenai landasan teori mengenai VoIp, SIP, Wi-Fi, perangkat LAN, softphone, Asterisk dan Android.

Bab I Pendahuluan 4

Universitas Kristen Maranatha BAB III PERANCANGAN DAN REALISASI

Dalam bab ini akan dibahas mengenai hardware dan software yang digunakan, perancangan sistem VoIP, Perancangan aplikasi dan tampilan interface aplikasi Android.

BAB IV ANALISA DAN DATA PENGAMATAN

Dalam bab ini dibahas pengambilan data dan analisa terhadap data pengamatan.

BAB V KESIMPULAN DAN SARAN

Pada bab ini akan membahas mengenai kesimpulan dari apa yang telah dikerjakan dan saran untuk perbaikan dan pengembangan lebih lanjut.

71 Universitas Kristen Maranatha

BAB V

KESIMPULAN DAN SARAN

V.1 Kesimpulan

 Perancangan jaringan VoIP dan aplikasi softphone SIP pada smartphone Android berhasil direalisasikan dalam satu jaringan, yang penyebarannya terbatas pada kemampuan router meng-cover area/wilayah.

 Komunikasi suara client 104 Samsung Galaxy W dan client 105 Smartfren Andromax U dengan client lainnya (kecuali client 102 S. Galaxy Tab2) memiliki tingkat keberhasilan 100% dari 10 kali pengujian. Komunikasi suara antara S.Galaxy Tab2 dengan client lainnya (Laptop dan smartphone) memiliki tingkat keberhasilan 50% sampai 70%, hal ini disebabkan karena perangkat S.Galaxy Tab2 memiliki level sinyal Wi-Fi yang kurang stabil dibandingkan perangkat lainnya.

 Penggunaan smartphone Android dengan versi Operating System yang berbeda tidak mempengaruhi kerja aplikasi. Level sinyal Wi-Fi client saat pengujian juga mempengaruhi kualitas suara dan keberhasilan panggilan. Perbedaan spesifikasi yang dimiliki masing-masing smartphone juga mempengaruhi kerja aplikasi.

 Delay komunikasi antara 2 client dan 4 client yang saling berkomunikasi memiliki rata-rata waktu 0,43s dan 0,4s untuk komunikasi S.Galaxy Tab2 dengan S.Galaxy W, waktu yang dihasilkan hampir mirip karena kemampuan server Asterisk yang cukup handal dalam alokasi bandwidth.

V.2 Saran

Perancangan aplikasi softphone berbasis Android ini agar dapat dikembangan lagi tidak terbatas pada penggunaan koneksi Wi-Fi saja, namun dapat dengan jaringan lainnya seperti EDGE, 3G dan dapat terkoneksi dengan jaringan PSTN. Selain itu untuk perkembangannya aplikasi tidak hanya mendukung komunikasi suara saja namun juga kemam- puan komunikasi lainnya seperti message, video call, video message dll.
