VoIP Encryption in a Surveillance Society

Posted by Cindy Nishimoto on January 15th, 2012

March 7, 2007 lecture by Phillip Zimmermann for the Stanford University Computer Systems Colloquium (EE 380). Phil talks about how the debate on the use of crypto has shifted since the 1990s, when it was a clash between civil liberties and law enforcement – in the 1990s, the crypto debate was about averting omniscience in governments, but today the encrypted VoIP debate may be about averting omniscience in criminals.

New PC Accessory Dramatically Improves Voice Quality Over the Internet

Posted by Cindy Nishimoto on January 13th, 2012

— July 10, 2002

Westlake Village, CA — July 10th, 2002 – MicroElectronicDesign has created the ideal PC accessory for anyone who wants to clear up their voice quality on the Internet. The device is called “WebPhone Jack” and uses advanced proprietary digital signal processing algorithms with audiophile class components to clear up conversations over the World Wide Web.

Originally designed to interface Microsoft’s Netmeeting product with speakerphones in the corporate environment; this stand-alone hardware DSP based device happily interfaces with all H.323, SIP and other VoIP software including Microsoft and Yahoo Messenger programs.

Unlike competitive units, which use simple, out-dated echo cancellation circuits, WebPhone Jack’s DSP automatically adjusts for variations caused by Internet traffic and telephone set quality in real-time.

“Currently the common trend in PC design is to incorporate sound card circuitry onto the motherboard itself. This creates a noisy environment resulting in headset users experiencing ‘motor-boat’ type background noise when they speak into the microphone. The WebPhone Jack eliminates this problem by properly terminating the audio connections to these motherboards” explains Dinesh Bhatia, CEO/CTO of MicroElectronicDesign. “With WebPhone Jack – vocal clarity is dramatically improved over simple headsets regardless of their quality or cost.”

snom technology AG launches first client side support for ENUM in the latest snom200 IP Phone.

Posted by Cindy Nishimoto on January 10th, 2012

Berlin, Germany & Dallas, TX — February 20, 2004

snom technology AG, the Berlin based German SIP Phone manufacturer, announced at the Internet Telephony show in Miami that it now supports ENUM a new industry standard for mapping regular phone numbers to IP Phone addresses. This new system will be key to meshing the conventional telephony platform with the new world of IP Telephony.

„ENUM is a milestone in the usability of SIP” says Dr. Stredicke, founder and executive of snom. Using ENUM, we can address people who don’t even know how the packets find their destination and if the destination is a traditional phone or a voice over IP-phone. It links the easy-to-remember Email-style addressing with the simple-to-enter PSTN numbering scheme so that in all situations it is as convenient as possible to locate the destination of a call.

Richard Shockey, NeuStar Sr Manager Strategic Technology Initiatives and IETF ENUM WG co-chair remarked, “The SNOM phones are the first real telephones or VoIP software I’ve seen to flawlessly incorporate ENUM technology (RFC 2916) to translate E.164 telephone phone numbers into SIP URI’s and establish a SIP VoIP session. The ENUM resolver in the SNOM product has no demonstrable effect on call setup times that I’ve been able to detect. In short, it works! “

Mr.Shockey added,” With 23 nation states now in the process of ENUM trials and discussions, products like the SNOM will be a key to moving the global ENUM initiative forward.”

Alexander Mayrhofer of the nic.at Austrian governmental domain registrar and a pioneer for European ENUM “snom seems to be the first who has integrated ENUM lookup into a SIP hard phone that allows routing of SIP calls via common phone numbers from the client side using user specific dial plans. An advantage to this method in contrast to the server side ENUM routing is more transparency to the user: The phone displays the resolved destination URI before placing the call”

Several counties like Austria, Sweden and Korea already put their national numbering plan into ENUM databases. Other countries like Germany are currently trying out ENUM, it is expected that North America and other regions will soon follow (NANPA, http://www.nanpa.com). snom is participating in the German ENUM trial and can be reached both over PSTN and VoIP with the same number +49.30.39833.0.

About snom technology, AG.

snom is a recognized technology leader in the area of VoIP phones, with a particular focus on SIP. Founded in 1996 and based in Berlin, the company has constantly pursued a commitment to innovation, open standards and SIP.

snom manufactures state of the art, affordable VoIP phones with a high cost-performance ratio and a range of practical SIP applications for business and service providers. http://www.snom.com snom products are distributed in the US, Canada and Latin America by ABP International, Inc. http://www.abptech.com +1-972-745-1221

Restricting VoIP and WiFi Costs South Africa Its Position as a Technology Leader in Africa

Posted by Cindy Nishimoto on January 7th, 2012

— May 28, 2004

Commentary written by bridges,org in collaboration with the East and Southern Africa Centre for International ICT Policy (ESA-CIP)

South Africa is celebrating ten years of democracy — a period during which the country has shown progressive leadership, including explicitly targeting information and communications technology (ICT) as an enabler of socio-economic development. In its re-election campaign this year, the Government promised to focus on poverty alleviation and job creation. But, ironically, the Government’s legislative efforts affecting new technologies like Voice over Internet Protocol (VoIP) and Wireless Fidelity (WiFi) are actually working against the development goals it seeks to achieve.

On one hand, the South African Government has taken unparalleled steps in forming national and international advisory councils to advise President Mbeki on how to extend the benefits of ICT to all citizens. However, existing telecommunications and convergence policies are not keeping pace with technological progress, and communications costs remain high as a result. Moreover, the Government has failed to provide a coherent legislative framework for ICT. Unless the Government aligns its intentions and actions it may undermine the country’s position as a technology leader in Africa.

One example is South Africa’s strategy to create jobs by enticing international call centres to the country. These centres — common in places like India — provide outsourced services using high bandwidth connections and VoIP platforms. VoIP converts calls to data and carries them like messages on any data network (including the Internet), which lowers costs, but can threaten the earnings of traditional telecommunications providers. Call centres provide telephone support services to developed countries from their bases in developing countries where labour is cheap, bringing cash to local economies. VoIP can also support socio-economic development more generally by bringing the benefits of efficient data network use and lowered call costs to individual consumers, small businesses, government agencies, and community organisations. Yet existing legislation that limits the use of VoIP in South Africa stifles advances in this area.

South African law also inhibits the use of WiFi technologies that could help bring the Internet to under-serviced communities. WiFi creates a high-bandwidth network using certain radio frequency transmissions that cover short distances. It is cheap to implement, largely because it does not require traditional wire infrastructure, and can be used to extend the reach of telecommunications and “backbone” Internet connectivity at low cost. And this in turn offers an effective channel for the delivery of many development services to under-serviced and rural communities. But it also jeopardises telecommunications profits.

Developing countries and communities with low telephone penetration stand to benefit the most from the introduction of new technologies like VoIP and WiFi. Gone are the days of voice traffic over traditional copper wire (which is often stolen), and separate cabling for data transmissions. There are huge cost savings to be gained in under-serviced communities by rolling out technologies that allow for both voice and data services on a single, combined, cost-effective network. Moreover, until recently VoIP and WiFi were only available to people with access to personal computers, but technology advances are extending this reach. For example, WiFi can be used to connect handheld devices to the Internet. And instead of requiring a computer with VoIP software, now people can use a regular telephone handset to dial to an intermediate computer connected to the Internet that will convert their call to VoIP.

Across the continent, other African countries are moving to the forefront. Algeria, Mauritius, Mali, Nigeria and Kenya have legalised VoIP and WiFi. For example, the Algerian Government recently approved several Internet Service Providers to use VoIP to legally compete on international calls. Prior to this, only the incumbent telecommunications operator was allowed to offer international call services, costing six times more. These progressive governments are boldly embracing new technologies to gain the long-term benefits of ICT, despite potential short-term losses in revenue as incumbent telecommunications providers restructure their approaches.

Currently, the provision of VoIP services in South Africa is only allowed in areas where less than five percent of the population have access to a telephone. The Government maintains that such restrictions will encourage companies to provide telephone service to these outlying regions and thereby rectify the imbalance in technology access between modern, urban hubs and under-serviced and rural communities. WiFi is also restricted to use by individuals or organisations within the confines of their own premises. So “hotspots” are okay, but connecting offices across town is not. In South Africa, it appears as if Government policy-makers either do not understand the development potential offered by these technologies, or they are just not ready to let go of the entrenched revenue streams from Telkom’s stranglehold on the market.

Nonetheless the use of these effective, cheap technologies is growing in South Africa — albeit illegally — including in different spheres of government. For example, local government agencies are connecting remote departments with WiFi networks that are well-suited to carry VoIP calls. Their existence is no secret, with public tenders in the local media calling for the installation and maintenance of these systems.

Removing restrictions and allowing competition to thrive in the communications sector will lead to greater choice, lower prices, and the proliferation of innovative services. This will in turn benefit the development needs of under-serviced and rural communities, where communication services are prohibitively expensive, as well as the corporate needs of businesses wanting to enter the value-added network market. All that is holding back the unlimited provision of VoIP services in South Africa is the public announcement of a date, at the Minister of Communication’s discretion, from which VoIP will be legal. This is a seemingly easy step, yet one not taken. Consequently, business leaders, development practitioners and the ordinary consumer alike are suffocating under an artificial constraint on telecommunications growth.

And in the meantime the South African Government, with all its right intentions, is increasingly losing its position at the technological forefront in Africa. An apparent reluctance to embrace new technologies must not be allowed to hinder the creation of jobs and wealth for the people of South Africa. Every citizen should understand the socio-economic development potential of new technologies, and call upon the Government to drive the changes needed to allow their widespread use. Unless the South African Government alters its course in this area, during the next election voters may well be asking why the Government has not delivered on its promises.

The Single Most Important Thing to Know About Computer Phones (VoIP)

Posted by Cindy Nishimoto on January 6th, 2012

— December 5, 2004

The single most important thing to know about computer phones, aka VoIP, is Security. Security involves privacy of phone calls and vulnerability to viruses, worms, Trojan horses, and unscrupulous computer hackers. Over 90% of voice over ip telephony (VoIP) computer phones use a standard, publicly available codex and protocol to transport voice conversations. Industry standard codex such as G.711, and industry standard packet protocols such as RTP, are open and interpretable. Like many peer-to-peer solutions, private information about “buddy” lists or call patterns, etc., are not confidential. In addition, users are vulnerable to decoding after a packet interception when traveling over the internet.

Here’s how VoIP services should protect your security, even on dial-up, wireless, satellite, and cable connections.

Call Security: The VoIP should be compressed using a proprietary codex that is transported over the internet using proprietary packets. Only that particular VoIP’s service software should be able to interpret the headers and data contained in that particular VoIP service’s packets.

Computer Phone Identity: When a VoIP computer phone is first installed, a phone number and password should be required to protect against unauthorized installation. Each VoIP computer phone’s setup process should combine the phone name and hardware data from the PC on which it is installed, thus creating a unique ID string known only to that VoIP service’s server. This unique ID should be associated with the PC that “owns” the VoIP computer phone, and also prevent one person from reconfiguring their VoIP computer phone to spoof another. In addition, it should also prevent someone from copying that particular VoIP’s software to another PC and then using it without having gone through the password-protected installation process.

Client Server Model: A VoIP service provider should follow a client-server model. The VoIP softphone “client” should share information only with that particular VoIP’s server. This means, that unlike some peer-to-peer solutions, private information about “buddy” lists or call patterns, etc., are entirely confidential. The VoIP provider’s server should be behind a highly secure firewall in a professionally hosted facility.

Softphone Setup: Firewalls vary widely and each network configuration may be quite different. When a VoIP softphone initializes, it should discover its ability to reach that particular VoIP’s server and use a variety of ports and protocols for placing calls, depending on the results of its discovery. In a stricter environment, the VoIP softphone should use the same path the firewall already permits for web browsing, typically TCP ports 80 and 443. This allows users to make calls from anywhere without compromising or reconfiguring their firewall.

The VoIP softphone should be able to initiate conversation with that particular VoIP’s server and keep the server updated as to its status. No public IP address should be setup for the PC running the computer phone, thus enabling the user the flexibility to move from network to network without concern. The particular VoIP computer phone should be compatible with Network Address Translation (NAT) and Port Address Translation (PAT), and the kind of dynamic addressing that is found in wireless “hotspots”, hotel internet access, and dial-up.

Monitoring Capability: A strong security model should include an auditing mechanism to monitor usage and activity. As such, each VoIP computer phone should include its own usage log, enabling users to look through their history of inbound, outbound, and missed calls. In addition, the VoIP service’s website should provides users the ability to view all individual phone call charges.

To experience a 7 day free trial secure line with patented technology, and with no contracts, obligations, or hassles, visit http://www.superiorvoip.com/PTL4ever Lines will simply go dead at the end of the free trial period unless you decide to activate the service.
