PC – Telecommunication PFA

If you make international calls, and are not yet using internet phone service, you are probably spending way too much money. International calling rates are at an all time low with most VoIP providers, averaging less than .05 per minute! If you have friends or relatives overseas, and want to save money by making call free international.

The word ‘free’ is like honey to the ears. Be it free shirts, free samples, coupons or even VOIP calls, we all will be definitely interested. Free VOIP calls are the latest buzz in the VOIP market. Everywhere we go we come across many VOIP providers who offer free international calling facilities to their customers. The voice quality and the call rates vary from company to company.

Whatever your calling needs are, there is a VoIP provider out there with a plan that is just right for everyone. The key to finding the best VoIP provider for your needs is to know what you want in the way of calling options, and then shopping around for the provider that offers the type of service plan you need. The quality of internet phone service has come a long way in the past couple of years, and the price cannot be beat. A broadband internet connection is required in order to use VoIP, and for the best quality and most cost savings it’s best to have cable internet or DSL.

Now you can call your friends in many countries around the world simply free of charge. You can also get free number for receiving international calls. Free calling from one PC to another was around since the start of the internet but now you can make call to standard phones for free.

Domestic and international calling cards are available for purchase in more and more places. The main options are to buy through an online calling card website or to buy at a retail store. Sometimes this isn’t possible because you need a card in a pinch – like during a trip. But if you are able to plan ahead, you will get much better calling card value – and avoid calling card scams, at the same time.
There are five main reasons to buy calling cards online:
Easier to identify and compare calling card vendors online
Easier to check company reputation and calling card complaints history
Harder for shady companies to hide calling card rates and fees
Easier to compare calling card prices and features for several different cards
Easier to use advanced features like PIN-less dialing and speed dial
The bottom line is that you will find the best calling card deals for your specific needs much more easily if you shop online.
While there are sketchy providers online, calling card scams appear to be concentrated with off-brand calling cards sold in retail and convenience stores. Cards sold under recognized brand names and/or through online outlets seem to face fewer complaints. A major reason for this has to do in part with packaging. In retail stores, companies are very limited in the amount of information they can provide due to the small size of the cards. As well, concerns about security and shoplifting force many store owners to limit browsing and comparison shopping. As a result, unscrupulous companies have the perfect environment to over-promise and under-deliver.
ADSL2 is an innovation in Internet technology that makes use of the cutting-edge mechanism to offer high-speed data transfer from a PC or a computer terminal to the network of networks – the Internet. DSL, which stands for Digital Subscriber Line, is the standard that facilitates carriage of data bits from the telephone connection with the help of which one can take up voice calls and even carry out video conferencing. ADSL, which stands for Asymmetrical Digital Subscriber Line, is the familiar and the advanced version that lets an Internet user to download at a substantial speed however the uploading speed is expected to be comparatively low.
This standard is meant to offer a high-speed connectivity to various computers that are interconnected within a particular network. With the working characteristic that is capable to operate at twice the speed of a normal ADSL modem now the upload speed of 24 Mbps and download speed of 3.5 Mbps is no longer a distant reality.
There are hundreds of thousands of Australians who are unable to get ADSL2 or Naked DSL even when it is available in their local exchange because their phone line is connected via Pair Gain, a sub exchange or a RIM.
They are offering the best deal in Australia to provide better platform to explore the world via diversified knowledge of internet (Cloud) by using cheap ADSL 2 to explore world and gain knowledge.

VoIP is probably the least understood telecom subject – even among dealers. So – here is a quick primer to get you up to speed.

Today, commercially available VoIP comes in five (5) basic flavors:

1. VoIP Dial Tone
2. VoIP SIP Trunking
3. VoIP PBX Gateways
4. VoIP Extension Phones
5. VoIP to the PC

VoIP Dial Tone:
This is what most people mean when they say “Does this phone system support VoIP?” Companies like Vonage, Packet-8 and Lingo offer VoIP phone service that competes with local and long distance phone companies. They will gladly tell you that their service is not usually dependent on what type of PBX you use, but you have to ask. In fact, you could hook up a $10 single line telephone to their service and it would work.

To the PBX, it’s just another POTS line (Plain Old Telephone Service). There are many companies that claim to have a new PBX that work with these VoIP lines and suggest that you switch over to their hardware. Unfortunately, they fail to tell you that it is totally unnecessary since these circuits will work with any phone system or any single line telephone. Before they get connected to your PBX or home telephone, they have been converted to look like regular analog lines.

VoIP SIP Trunking:
SIP Trunking is Dial Tone that is obtained from an ITSP (Internet Telephony Service Provider). Instead of breaking the circuit out into analog channels, it stays digitally packetized from the ITSP’s Central Office to your equipment. SIP Trunking is obtained using a broadband Internet connection that plugs into your PBX. Typically, each voice channel (also referred to as a ‘session’) requires between 60k and 85k of bandwidth, depending on the codec employed. SIP is an acronym for Session Initiation Protocol.

The service is usually sold through Telephone Equipment Vendors such as KX-TD.COM because of the initial complexities of its one-time setup. This is fairly new technology and it is rapidly growing in popularity due to the low monthly costs. Currently, Panasonic supports SIP Trunking on all of their KX-TDE IP PBX’s, all of their KX-NCP Series IP Converged PBX’s and the new KX-TDA50G. SIP WILL be the dominant technology going forward.

VoIP PBX Gateways:
These are essentially “H.323 Tie Lines” between PBX systems. An example of this would be a company that has multiple locations and the desire to connect them together to achieve free intercom calling. There are several ways to do this from something as simple as D-to-A Converters (FXO & FXS Cards) in your router. Most advanced IP PBX’s actually allow you to install special VoIP Gateway cards, which in turn connect across the Internet to other PBX’s with the same card to create Tie Lines.

The advantage to this is that it sends other call information, such as the extension name and number, lamp information, distinctive ringing, etc. through the gateway. For added security, VoIP Gateways from Panasonic operate within a VPN (Virtual Private Network) or across Frame Relay Network. Panasonic KX-TDA, KX-TDE and KX-NCP Series systems all have this option.

VoIP Extension Phones:
VoIP Extension Phones are becoming very popular. Today, there are three (3) types of VoIP Extension Phones, (i) Single Line Analog sets, (ii) Fully Integrate Multi-button Key Sets and (iii) Soft Phones. Single Line Analog sets are also called “dumb phones” since they do not digitally pass information between the phone and the PBX. These are like the old fashion phones that we all had in our homes in the 70’s & 80’s. Fully Integrated Multi-button Key Sets are “smart.” They look and act exactly like your wired desk set.

The difference is that the wired desk set is near the PBX and the VoIP Phones can be half way around the world. Instead of a wire, they use the Internet, along with some sophisticated built-in software to make the connection. Panasonic remote IP Phone users can access every feature that a wired phone user can. For added security, VoIP Gateways from Panasonic operate within a Hardware VPN (Virtual Private Network) or across Frame Relay Network.

Soft Phones are communication software applications that appear on a PC or laptop screen as PBX extensions. Soft Phones typically operate in a less secure environment, such as a Software VPN or no VPN at all. Panasonic KX-TDA, KX-TDE and KX-NCP Series systems all have fully integrated multi-button IP phone options and the ability to use Soft Phones.

VoIP to the PC:
VoIP to the PC technology relies on processing power from a Personal Computer or other external processor. Unless you are willing to dedicate a PC for each conversation, this is not a wise choice (yet). VoIP to the PC would be services such as Skype. Skype is in the process of Beta Testing their SIP product with several PBX systems, including Panasonic PBX systems. This is an emerging technology and has some merit – especially internationally.

We will continue to keep an eye on these developments and when Skype has demonstrated that they can adapt to the needs of commercial users, we will reclassify them as a VoIP SIP Trunking product. There are other more gimmicky companies in the VoIP to the PC category such as Magic Jack. We do not consider Magic Jack to be a viable product for anyone.
