IP04 CaseIP04 CaseBapak2, Ibu2 dan Kawan2 yang saya hormati,

Terlebih dahulu saya ingin memberikan penghargaan yang tinggi kepada Bapak Dr. Onno W. Purbo, yang telah banyak menyumbangkan pemikiran dan hasil karya bagi penerapan TIK yang Pro-Rakyat Kecil, seperti RT-RW Net, Wajanbolik, Open Source Software (Linux), dan lain-lain lagi.Namun sangat disayangkan bahwa pemikiran dan hasil karya beliau lebih banyak mendapat perhatian dan diterapkan di luar negeri, khususnya di Kanada, Eropa dan negara-negara berkembang.

Kali ini beliau menemukan informasi yang dapat menjadi titik balik kebangkitan Industri TIK Nasional, serta yang dapat mempercepat kemajuan teknologi dan perekonomian bangsa Indonesia, sebab yang disampaikan oleh beliau adalah sebuah informasi lengkap untuk memproduksi hardware dan software sistem teleponi (VoIP) baru yang gratis, baik copyright hardware-nya maupun software-nya (Open Source).

Kita bebas untuk meng-copy, memperbanyak dan memproduksi Sistem Free Telephony ini bagi kemajuan dan kesejahteraan bangsa Indonesia, sebab proyek ini, yang dinamakan Free Telephony Project, memang dirancang untuk dibagi (di-share) bagi kemajuan ummat manusia sebagaimana konsep Software Open Source (versus konsep Proprietary Software, yg ingin dinikmati keuntungannya bagi pemiliknya sendiri). Jadi ini sangat cocok bagi negara-negara berkembang seperti Indonesia, untuk dapat mengejar ketertinggalannya dari negara-negara maju.

Hardware sistem ini terdiri dari sebuah Asterik IP-PBX, termasuk multiple analog ports (T1 atau E1), dan tanpa memerlukan lagi Personal Computer. Biaya pembuatannya tidak lebih dari beberapa ratus Dollar.

Produk awal dari Proyek ini dinamakan IP04, yaitu sebuah Sistem Telepon murah yang mampu untuk menyalurkan panggilan telepon dari sistem telpon analog ke sistem telpon VoIP (Internet Telephony). Sistem ini telah dirancang secara professional dan telah dapat diproduksi secara massal saat ini.

Tujuan Proyek ini adalah untuk membuat biaya telpon se-rendah mungkin, sehingga siapa saja manusia di bumi ini bisa melakukan panggilan telpon, karena ini merupakan Hak Azasi Manusia untuk berkomunikasi kepada sesamanya.

Ini sangat cocok dengan tujuan proyek USO, yang mungkin sudah menjadi takdir Illahi, Tender Proyek USO Indonesia saat ini di batalkan. Saran kami agar proyek ini di review kembali dengan diperolehnya informasi tentang tersedianya Sistem Telepon murah IP04 ini. Bila sistim ini diproduksi secara massal, oleh produsen2 Indonesia, dengan dana dari Proyek USO, maka industri TIK nasional dapat segera bangkit kembali.

Mudah-mudahan para pembuat kebijakan TIK Nasional Indonesia bersedia untuk mengakomodasikan info terbaru Sistem Telepon murah IP04 ini, sebagai titik balik kebangkitan Industri TIK Nasional, dan sebagai awal kebangkitan bangsa Indonesia di bidang kemajuan teknologi dan kemajuan perekonomian bangsa Indonesia, sebab akan dapat meningkatkan kemandirian bangsa Indonesia dari ketergantungan pihak asing (vendor asing, hardware dan software asing).

Informasi lengkap tentang Proyek Free Telephony dan Sistem Telepon murah IP04 dapat dilihat dibawah ini.

Semoga mendapat perhatian para pembuat kebijakan nasional di bidang TIK, serta membawa kemajuan teknologi, perekonomian dan kesejahteraan bangsa Indonesia.



Free Telephony Project



The goal of this project is to provide free hardware designs for telephone systems. Both the hardware and software are open. You are free to copy, modify and re-use the hardware designs. The hardware for a complete embedded Asterisk IP PBX (including multiple analog ports or a T1/E1) can be built for a few hundred dollars. No PC required!

Our first product is the IP04. The IP04 is a low cost phone system that can switch phone calls from analog phones or phone lines over the Internet using VoIP. The IP04 is a professionally designed product that is in volume production today:


IP04 in production case

The hardware designs collected on this site have been developed by a dedicated group of telephony professionals. The technology is complex, hence most of this web site is deeply technical. However the goals of the project are easy to understand – we want to lower the cost of telephony for everyone on the planet. Making a phone call should be a human right, not a privilege.

For a non-technical introduction:

  1. NEW We have recently released a white paper outlining the use of the IP04 for VoIP in developing regions.
  2. Open hardware telephony really can “connect the planet”. Here is a article published on Next Billion that describes the possibilities for the developing world.
  3. This blog post introduces the business and social possibilities of Open Hardware.

Why Free Telephony Project?

  1. Our designs are free as in speech, like Open Source software. Anyone is free to copy, modify, manufacture.
  2. Recent breakthroughs mean that free software can now do most of the work in a telephone system, work that was previously done by specialised, expensive hardware. This means a dramatic drop in hardware prices is possible. Thus hardware costs are getting closer and closer to $0. Our job is to help them get there faster – by releasing royalty free designs and encouraging their mass production!


Would you like to experiment with your own embedded Asterisk IP-PBX with multiple analog ports? A good start is to order an IP04 Four Port IP-PBX. This is a fully assembled, hackable IP-PBX based on open hardware and software designs.

The projects on this site are organised along software and hardware lines:

  1. uCasterisk (you-see-Asterisk) is a set of scripts, makefiles and patches to build embedded Asterisk for uClinux. Target hardware is the Blackfin BF533/BF537 STAMP boards. This project is nearing the end of it’s useful life and is being replaced by Astfin.
  2. GPL Hardware is a project to develop open (GPL) telephony hardware for the Blackfin platform. The range of designs includes FXO/FXS analog boards, a BRI ISDN Appliance, single span E1/T1 and a Blackfin BF532 mother board.
  3. Oslec is an open source high performance line echo canceller that outperforms the Zaptel echo cancellers used in Asterisk. Although developed for the Blackfin it is also in wide use on x86 platforms.

There is a project forum here.

There are also several related sites:

  1. The BlackfinOne is a high performance DSP motherboard suitable for embedded telephony. The design is completely open (free as in speech).
  2. Astfin is the latest Blackfin uClinux Asterisk distribution. The authors have used Buildroot to make the very complex embedded build process very simple. Astfin is the successor to uCasterisk, and where Blackfin Asterisk software development is now focused.
