VoIP or Voice over Internet Protocol, also known as IP Telephony PBX PBA Doha Qatar or Internet Calling is an alternative way of making phone calls that can be less costly than standard telephone calls over PSTN (Public Switched Telephone Network).
This article explains what VoIP is, how it works and the advantages and disadvantages of VoIP calling over standard, traditional telephone services.
How does VoIP work?
VoIP works by taking standard analog audio signals and converts them in to digital data that can be transmitted over the internet using the IP Protocol.
Interestingly there isnít just one way of placing a call via VoIP, instead there are three different types of VoIP service that are commonly used today. These are:
ATA: This is simplest and most common form of VoIP calling. By using an ATA (Analog Telephone Adaptor), you are able to connect a standard phone to your computer or your internet connection for use with VoIP. An ATA is an analog to digital converter which takes the analog signal from your phone and converts it into digital data for transmission over the internet. Itís extremely straight forward to use and so it has been widely adopted around the world.
IP Phones: An IP phone is a specialized phone that looks like a regular phone with the usual handset you would expect to see, along with the cradle and buttons, however instead of hacing a standard RJ-11 phone connector, IP phones have an RJ-45 Ethernet connector instead. IP phones connect directly to your router and have all the necessary onboard hardware and software onboard to handle the IP call.
Computer-to-Computer: Of all three of the main systems, this would be the easiest way of using VoIP. Computer-to-computer VoIP calls use software loaded on your PC or device, a microphone and speakers (or headset) and your internet connection to allow you to make calls from computer to computer. Popular services like Skype utilise this VoIP platform to provide their services.
What are the advantages of VoIP services?
There are a lot of advantages to using VoIP over traditional phone services. These include:
Cost: For many businesses, VoIP is a way to easily cut down communication costs. The great thing about VoIP is it utilises pre-existing infrastructure without additional costs. In many cases VoIP services can be used for free with computers or devices that have the right software, and even in some cases with mobile and landline phones. When you consider the costs associated with international business calls, this becomes an obvious alternative for business owners around the world.
