What is VoIP calling?
VoIP stands for Voice over Internet Protocol, which means calling another person using the Internet instead of the traditional phone lines. This technology has become popular after the introduction of 3G phones which have enough bandwidth to convert your voice into data packets and transmit it over the internet to the receiver.
The data packets contain your voice and are then converted to sound that is projected out of the speaker. This process continues and all this happens within microseconds that is never felt.
Therefore, there’s a difference between a Voice over IP phone call and a normal phone call.
What is the difference between a VoIP call and a phone call?
The difference between these calling procedures is obvious. In phone calls, you need both the phones within the range of the cell tower so that they can receive signals. Landlines were even worse as you need to have a physical cable connected to every device. In-app calling over the internet, you only need to have the internet connection either Wi-Fi or data network from any service provider and the call will get connected. It does not have limitations of having a number assigned and the need for the mobile phone to be in the range of the mobile tower of the service provider.
The best example would be, if you travel abroad and your mobile network is out of range, then via Wi-Fi connectivity, you can call your family and friends back home free of cost, provided they have the same app installed.
What is SIP?
SIP or Session Initiation Protocol is used to initiate, maintain and terminate any media communications while conducting a Voice over Internet Protocol call.
VoIP calling is definitely the future over the Public Switched Telephone Network as it offers:
- Low Cost: You will not be charged per minute but only for data consumed.
- Free Over Wi-Fi: If you have an unlimited Wi-Fi subscription, then calling through Wi-Fi will be considered free as you have to pay for the fixed monthly charges whether you use the Internet or not.
- VoIP devices are portable and need not be fixed like Landlines.
- VoIP calling does not require you to be in the range of Service Provider’s network tower.
- Some VoIP calling apps does not need you to obtain SIM Cards or any number.
- Voice over IP calls do not include any roaming charges
- VoIP call apps enable the users to send free messages which are still chargeable with many Service Providers.
- VoIP calls have been upgraded from voice to video calls
- VoIP calls apps also allow the users to communicate with Instant chat service.
- Voice over IP calls has integrated many special features with their apps like Screen Sharing, Conferencing with at least 50 people at the same time and transfer of files.
With a mountain load of benefits, VoIP calling does have a few limitations:
- Every app requires both the parties involved in the communication process to install the same software in both devices.
- Voice over IP does not work with a slow internet connection.
- The technology is more complicated than simple Landline phones, the latter would work even if there is no electricity.
- As some apps do not require a specific telephone number, it becomes difficult to track the calls.
- A study concludes that people have started spending more time talking on cell phones, as there is no charge, and this has resulted in rising health issues.

Voice over IP phone call has already been a part of our social life since the advent of social media apps. It started initially by allowing us to send voice messages and later developed into voice calling and video calling. The benefits of this technology are countless, and a few limitations must not deter us from using these apps. Not all these apps are the same and each developer has tried to provide a unique feature in their app which is not available in others. It is my personal view that WhatsApp and Skype fulfill my personal and professional requirements.
