How Voice Over Internet Protocol Works?

How Voice over Internet Protocol (VoIP) works is a mystery to many Singapore businesses big and small. But if you understand its functionalities, you can easily use the technology to your company’s advantage.


Voice over internet protocol is a method of taking audio signals and transfiguring them into packets of data that can be transmitted through the internet. With this technology, the internet can now be used as a pathway for free phone calls. The practical outcome, if the technology is integrated to a company’s system, is that the need for a telephone company is eliminated, bypassing the service charges of telephone lines entirely. VoIP is an innovative technology that can potentially modify the world’s phone systems.

How does it work?

Voice over internet protocol from providers such as in Singapore use an existing internet line to make and receive phone calls. Instead of the calls travelling out of the telephone line, the voice of the caller is converted into packets, which will then be transmitted through the internet at the same speed as the internet connection.


On the receiver’s line, the packets are converted back to a regular voice sound just like a normal phone call. The person receiving the sound won’t even notice the difference. Moreover, with VoIP, people can call landlines and cellphones. Computer-to-computer calls are also possible. Both parties speak into a computer microphone and listen for the other line’s response through headsets or computer speakers.

What equipment is needed?

Voice over IP calls can be made from regular phones with an adapter provided by a VoIP Singapore company, or special IP software installed on computers to make calls. The software is most beneficial to people who do a lot of travelling since it can receive and make calls from anywhere as long as there’s an access to the internet. Also, to ensure security and best voice quality, consider using the voice over IP system on a private network.

What to watch out for?

Make sure the VoIP service supports 911 calling. Most large establishments are tied in to 911, so this shouldn’t be a problem. But for smaller companies, pay attention to this matter. Alternatively, one can maintain an existing telephone line for emergency calls and use the voice over IP line for everything else. Furthermore, when subscribing to a VoIP Singapore service, extra features like caller ID, wall transfer, call waiting, return call, repeat dial, and three-way calling, should be provided without additional charges.


All in all, voice over internet protocol is a great option for businesses and individuals looking for a cost-efficient alternative to expensive telephone services. Check out several VoIP Singapore providers and see how Internet telephony can provide convenience to you and to your company.
