Voice over Internet Protocol (VoIP) technology means that can deliver the human voice, video and data over an IP network the Internet. How to use VoIP, we make phone calls via PC or telephone terminals.
VoIP is widely used in big cities, because of cheap also infinite distances, even across countries. Ok, we discuss again how VoIP.
The terminal will communicate with the gateway through local telephony. Relations between the gateway is done through the IP network range ragama. Network IP biased form of any packet network, including ATM, FR, Internet, Intranet, or E1 line.
Bali including the majority of the island using VoIP as a way to communicate. Simply use the computer connected to the Internet, the computer is online the sesame communicate bias for FREE.
Voip offers cheaper transport signal, additional features, and transparency of computer data. Voip obstacle now is reliability under normal telephony, and about the standardization that will comes to interoperability. These barriers are still an obstacle.
By using a VoIP phone, a lot of advantages that we can. Among them is in terms of cost, obviously cheaper than traditional phone rates, because of the global nature of IP networks so as to international relations can be reduced up to 70%.
In addition, maintenance costs can be on tap for separate voice and data networks, so that the IP Phone can be added, moved and changed.
This is because VoIP can be installed in any ethernet and IP address, unlike traditional phone must have its own port in Central or PBX. Very interesting right to use VoIP?
The interesting thing about VoIP are many ways to make a call. Currently there are 3 different types of methods that are most commonly used to perform layalan Voip, namely:
1. ATA (Analog Telephone Adaptor)
The way the simplest and most common is to use a device called an ATA. ATA allows us to connect a regular phone to a computer or connected to the internet to use Voip. ATA is a conversion tool from analog to digital signals. The way it works is to transform the analog signal from the phone and turn it into digital data for transmission over the internet. Providers such as Vonage and AT & T Callvantage making tools ATA and give it away for free to customers as part of their service. They stay open ATA, installing telephone cable to the instrument, and VoIP can be used. Several types of ATA packaged and bundled with additional software that must be installed on the computer to configure the ATA, but in general it's just a very easy setting.
2. IP Phones
This special telephone seemed the same as a regular phone. But besides having a standard RJ-11 connector, IP Phones also has an RJ-45 connector. IP Phones connect directly from the phone to the router, and IP Phones existing in all hardware and software that is already installed inside the support to call IP. Soon, Wireless IP Phone (LAN) will be available, and allows users to make VoIP calls from hotspots are available.
3. Computer-to-Computer
This method is definitely the easiest way to make Voip calls. You do not even have to pay a penny to make long distance calls. There are several companies that offer low cost programs that can be used free even to make Voip calls. You must provide only a program (software), a microphone, speakers, soundcard and an internet connection, preferably a relatively fast Internet connection such as cable or DSL connection. In addition to monthly ISP fee, usually no more cost to call Computer-to-Computer, how far away.
Well, that's how VoIP is now more sought after and more people, especially the developed and developing countries. In addition to saving, better quality and without limited distance. Let's switch to VoIP!
