VoIP is now HOT in Korea

Posted: December 23rd, 2008, by Yunho Chung

Now VoIP is hitting Korean communication market. From October 31 number portability for VoIP has began to apply, which means that people were able to change their fixed phone to VoIP without changing phone number. Previously, people should change their phone number to VoIP number beginning 070. New VoIP subscribers moved from fixed phone subscribers increased by 10 thousand for only four days since October 31. Also by November 27th, VoIP subsciber moved from fixed phone has increased by 100 thousand.

This growth of VoIP is mainly due to cheaper price, which is cheaper up to 85% comparing fixed phone. Because of economic depression, VoIP market growth will be more accelerated.  IDC Korea forecasted that Korean VoIP market will increase upto 1.4 trillion won (around 1.1 billion US dollar using current exchnage rate) by 2011 with 53% annual market growth rate.

In Korean VoIP market, LG Dacom firstly launched VoIP for home, myLG070. After that SK Broadband, Samsung Networks and KCT(Korean Cable Telecom) started to chase LG Dacom. Moreover KT, the fixed phone market dominator currently, also started to tap into Korean VoIP market even though they could cannibalize their fixed phone business.

Still VoIP marekt is much smaller than fixed phone(PSTN) market, but increasing rate is increasing more and more. Also some people is pointing out that VoIP would be the main issue for bundling such as DPS, TPS or QPS from 2009, not broadband whch has been the main item for bundling so far. In that reasons, VoIP market competition would be fiercer.

    Please let me elaborate more on VoIP. Voice over Internet Protocol has been around since many years. But due to lack of sufficient and affordable bandwidth it was not possible to carry carrier grade voice over Internet Protocol. But since the arrival of low cost internet bandwidth and new speech codecs such as G.729, G.723 which utilizes very low payload to carry carrier class voice it has recently been possible to leverage the true benefits of VoIP. G.723 codec utilizes only 6 Kbps (Kilo Bytes/sec) which is capable of maintaining a constant stream of data between peers and deliver carrier grade voice quality. Lets put this way if you have 8 Mbps internet connection, by using G.723 codec you can run upto 100 telephone lines with crystal clear and carrier grade voice quality. I am also a user of VoIP and have setup a small PBX at home. Since I have discovered VoIP I have never used traditional PSTN service.

    Dear readers, if you have not yet tried VoIP I suggest that you try VoIP technology and I bet you will never want to use the traditional PSTN phone service ever again. VoIP has far more superior features to offer which traditional PSTN sadly cannot offer.

    Also It has recently been possile to carry Video alongwith VoIP by using low payload video codecs. I cannot resist to tell you that by using T.38 passthrough and disabling VAD VoIP can carry FAX transmission, but beaware FAX T.38 passthrough will only work when using wide band protocols such as G.711, a-Law and u-Law.

    By using ATA (Analog Telephone Adapter) which converts VoIP signals into traditional PSTN you can also using Dial-up modems to connect to various dialup services. I wont go in to the details what VoIP can offer, to cut my story short VoIP is a must to have product for every business and individual.

    How VoIP Works

    When we make a VoIP call, a communication channel is established between caller and called party over IP (Internet Protocol) which runs on top of computer data networks. A telephony conversation that takes place over VoIP are converted into binary data packets streams in real time and transmitted over data network, when these data packets arrive at the destination these are again converted into standard telephony conversation. This whole process of voice conversion into data, transmission and data conversion into back voice conversation takes place within less than few milliseconds. That is how a VoIP is call is transmitted over data networks. I hope that now you understand basics of how a VoIP call takes place.

    What are speech codec’s and what role codec plays in VoIP?

    Speech codec play a vital role in VoIP and codec determines the quality and cost of the call. Let me explain you what exactly VoIP codec’s are and how they work. You may have heard about data compression, or probably you have heard about air compressor which compresses a volume of air in enclosed container, VoIP codec’s are no different than a air compressor. Speech codec’s compresses voice into data packets and decompresses it upon arrival at destination. Some VoIP codec’s can compress huge amount of voice while maintaining QoS which means use this type of codec will cost less because it will consume just a fraction of data network. Some codec’s are just not capable of encoding huge amount of voice they simply consume huge amount of data networks bandwidth hence the cost goes up.

    Following is a list of VoIP codec’s along with how much data network bandwidth they consume.

    * AMR Codec
    * BroadVoice Codec 16Kbps narrowband, and 32Kbps wideband
    * GIPS Family - 13.3 Kbps and up
    * GSM - 13 Kbps (full rate), 20ms frame size
    * iLBC - 15Kbps,20ms frame size: 13.3 Kbps, 30ms frame size
    * ITU G.711 - 64 Kbps, sample-based Also known as alaw/ulaw
    * ITU G.722 - 48/56/64 Kbps ADPCM 7Khz audio bandwidth
    * ITU G.722.1 - 24/32 Kbps 7Khz audio bandwidth (based on Polycom’s SIREN codec)
    * ITU G.722.1C - 32 Kbps, a Polycom extension, 14Khz audio bandwidth
    * ITU G.722.2 - 6.6Kbps to 23.85Kbps. Also known as AMR-WB. CELP 7Khz audio bandwidth
    * ITU G.723.1 - 5.3/6.3 Kbps, 30ms frame size
    * ITU G.726 - 16/24/32/40 Kbps
    * ITU G.728 - 16 Kbps
    * ITU G.729 - 8 Kbps, 10ms frame size
    * Speex - 2.15 to 44.2 Kbps
    * LPC10 - 2.5 Kbps
    * DoD CELP - 4.8 Kbps

    Switch to VoIP Today and you will never want to use traditional PSTN ever again.

Your windows vista activation key operating system is now reinstalled on your reformatted hard drive, and you are all activated without having to actually go through the product activation process.
    Remember, though, this won’t work for transferring activation information from one computer to another or if you alter the hardware, because then the information contained in your “wpa.dbl” file will not match the configuration of the computer. This trick is only for reinstalling buy windows 7 activation key online on the exact same computer after formatting the hard drive. To tell you the truth, I have never understood what the big deal is with product activation.
    The fact is that software piracy is rampant, and cheap windows 7 professional product key is the target for a large percentage of the piracy due to their dominance in the market. They have a right to try to stop or at least control that privacy, and the product activation seems to be a fair way of ensuring that only legitimate software owners get to benefit from using it. Users who reformat their hard drive and perform microsoft office 2011 product key finder mac a clean installation of the operating system will find that they need to reactivate the product.

    Follow the steps below to save the activation status information in office product key card 2010 and restore it once your system is rebuilt. No matter the reason, there are plenty of users who would rather never go through the windows activation key process again. Unfortunately for those users, they may very well run into a situation where they do. Product activation monitors the system configuration. If it detects a major hardware change or even too many minor hardware changes within a set number of days (I believe it’s 180 days before it resets) then it crosses the threshold and requires reactivation.
