Thread: New "Voice over Internet" technology.

  1. #1

    Default New "Voice over Internet" technology.

    VOIP isn't exactly new technology, but this article indicates that it’s starting to be adopted across the globe as an alternative for cheaper phone calls. I have used Skype a bit and I find it a very competent tool for communication. You can conference call and the sound quality is far superior to a normal phone line. Download it here.http://www.skype.com/ <font color="red">17,788,200 downloads and counting...</font id="red"> Warning....It uses about 5kb for each person, when connected. So people using 3 gig ADSL accounts could potentially blow their accounts. However it's still a wonderful program. I think a small glimpse into the future.

    TAIPEI (Reuters) - Ring Fu's company plays a small part in a global trend that he says will dominate telecommunications in the not-too-distant future.

    "A few years ago they said it was a toy. Now, the biggest companies in the U.S. are adopting the technology," he said.

    That "toy" is a technology called voice over Internet protocol, or VOIP, which transmits phone calls the same way e-mails are sent over Internet broadband connections and at much lower costs than conventional calls.

    <font color="red">"It will be the main conduit through which humans communicate over long distances, absolutely,"</font id="red"> Fu said.

    VOIP has been around for several years, but has taken off recently as technology improves and the spread of broadband Internet connections make it easy to use the service.

    Verizon Communications, the largest telephone company in the United States, launched VOIP services last week.

    The cost savings it offers make VOIP a threat to big telecommunications carriers. AT&T, the largest U.S. long-distance phone firm, said this month it would no longer seek new residential customers and would instead concentrate on corporate clients due to rising competition in long-distance services such as VOIP.

    <font color="red">Gartner forecasts that about 17 percent of North American phone lines will be replaced by VOIP services by 2008.</font id="red">

    Taiwan's Chunghwa Telecom faces similar challenges.

    "Chunghwa has the most to gain because it is the largest provider of broadband access. But on the other hand, it has the most to lose because it has the largest share of long-distance service," said Fu.

    TOUGH POSITION

    Chunghwa is aware of that.

    "The company is prepared for these future developments," said Hank Wang, Chunghwa's director of finance, referring to Internet voice services. "But there is no timetable for the rollout."

    The problem for Chunghwa is that any benefits from the new technology would cannibalise its traditional fixed-line telephone services, which made up 39 percent of revenues in the first half but continued to decline.

    "Chunghwa is in a tough position," said Fu Chi-chung, a vice president at Seednet, a distant second to Chunghwa in the Internet service provider market. Seednet launched IP-based telephony earlier this year.

    The decline of traditional telephony is good news for Fu and his company, DSG Technology, which saw net earnings more than double in the first half of 2004 after more than tripling last year.

    The 41-year-old Fu makes money by buying Internet access time at wholesale from Internet service providers and then reselling it along with IP phones and other equipment to customers.

    According to U.S.-based Atlantic-ACM, global wholesale VOIP minutes during 2001 exceeded 10 billion minutes and will reach 300 billion by 2006.

    About 90 percent DSG's clients are overseas, with the majority in the Middle East and Africa where long distance rates are high.

    <font color="red">"My customers often thank me for cutting their telephone bills by up to 90 percent," </font id="red">Fu told Reuters at his company, which listed in February.

    The United States has been a leader in VoIP because of a relaxed attitude from regulators and a large long-distance market, while Japan has been a pioneer in Asia with companies such as Yahoo Japan Corp. pushing the new technology, say analysts.

    In the rest of Asia, the acceptance has been slower due to regulatory problems and smaller domestic markets.

    "It will happen in Asia, no doubt about it," said Andrew Chetham, a telecoms analyst with Gartner in Hong Kong. "Businesses particularly will be looking to lower costs, absolutely."</b>

    Skype uses about 5 kb per second. So a 56K modem is possible. However the overseas latencies might be the problem. Im confident that a 56K would work in the SA Context however. Perhaps they might like to convert their line to ISDN. This would be more stable.

    Also Skype uses less with certain local connections. I chatted to a fellow from SAWireless the other day and the connection varied between 0.5 to 2.5 kb. So bandwidth varies with different type of connections. I'm on ADSL.

    It should work fine on dial up as long as there is nothing else running. According to the FAQ it uses 3-16 KB/s depending on available bandwidth so the quality may be slightly worse than ISDN but still acceptable.

    The amazing thing about Skype is the quality. It sounds like the person is standing right next to you when you use a good mike and ADSL. The speakers also matter. Very good little proggy!

    Skype compares with somebody talking in my ear, inside a soundproof room. That was for a local connection (Cpt PC to Dbn PC).

    Ok just some feedback ... I have done the following tests ...

    ADSL : Jhb - CT = Quality Ok - some crackling & breaking up ...
    Dial Up: Same

    ADSL : Jhb - UK = Quality Perfect - No crackling and about 2-3 breakups in 58 minute conversation (which cost R8.30 -- for the whole 58 minutes)
    DIal Up: Same

    My conclusion:
    There is no difference between ADSL / dial up when it comes to skype as long as you nod doing anything else on the link

    The difference comes if you talk from SA to SA in comparison to SA to europe ...
    as the trip is twice the length ...

    JHB -&gt; CT is JHB - CT(exchange) -&gt; Europe -&gt; CT
    JHB -&gt; UK is JHB - CT(exchange) -&gt; Europe

    So u skip a big link in the second one ...
    The only thing i would reccomend is a noise cancelling microphone.
    The reason for this is that your voice is compressed before it's sent. Voice can be compressed well, however all outside noise (white noise) can not be compressed that well - pure white noise has a 0% compression ratio - so if you cut down the noise you will get a better connection ...
