6 Key Differences Between VoIP and WhatsApp Call

When it comes to effective communication, whether for work or personal reasons, the tools we use make a big difference. Two popular options are VoIP (Voice over Internet Protocol) services and WhatsApp. Both offer ways to call and video chat over the internet, but they’re quite different in who they’re for and how they work. 

This article explores the distinction between VoIP and WhatsApp calls by looking at their features, how they work for international calls, and what kind of security they offer. This will help you figure out which one might be the best fit for you or your business.

Understanding VoIP technology 

VoIP, short for Voice over Internet Protocol, represents an innovative method enabling individuals to conduct voice calls through an Internet connection in place of traditional analog phone lines. 

In simpler terms, VoIP technology is about using your internet connection not just to access websites or send emails, but also to make phone calls anywhere in the world, often at a fraction of the cost of a standard phone service. 

This technology transforms your voice into a digital signal, allowing it to move across the internet. For businesses and professionals, this means the capability to handle a high volume of calls with greater efficiency and lower operational costs. 

What is a WhatsApp call? 

WhatsApp calling functions as an extension of the app’s messaging capabilities, offering voice and video calls over the Internet. This means that similar to a traditional VoIP call, your voice is converted into digital signals that are transmitted over the internet.

It also offers you the convenience of voice communication without the need for separate hardware or software designed specifically for internet calling. 

This makes WhatsApp calls particularly appealing for personal use and informal settings, providing an easy and cost-effective way to stay connected with friends and family globally, as long as both parties have the app installed and an active internet connection. 

The main differences between VoIP and WhatsApp Calls

1/ Quality of Service: 

Quality of Service (QoS) consists of key network performance metrics crucial for VoIP call quality. It includes latency (delay before data transfer), jitter (latency variability), and packet loss (dropped data packets). 

On the other hand, WhatsApp’s QoS heavily depends on the user’s internet connection, with bandwidth and network stability playing vital roles in call quality.

2/ Features and Functionality Comparison:

VoIP presents a range of advanced features that extend beyond fundamental call functions. This technology integrates capabilities like video conferencing, auto-attendant, and virtual phone numbers to enhance your communication needs. You can also personalize your setup with call recording, voicemail transcriptions, and CRM integration to customize your communication requirements.

Unlike traditional VoIP services, WhatsApp provides voice calls and messaging within a secure, easy-to-use platform. This approach ensures that anyone with a smartphone and an internet connection can make calls across the globe without needing technical know-how or additional setups. 

3/ Privacy and Security

VoIP systems, particularly those utilized in business settings, frequently integrate advanced security measures like end-to-end encryption, Secure Real-time Transport Protocol (SRTP), and Transport Layer Security (TLS). These measures are designed to protect data integrity and confidentiality across communication channels. Furthermore, VoIP services can be aligned with your organization’s internal security policies, offering precise control over data protection and user accessibility.

In comparison, WhatsApp calls benefit from the app’s end-to-end encryption feature, ensuring that conversations remain private and inaccessible to third parties, including WhatsApp itself. However, it is crucial to acknowledge that the security of WhatsApp calls also depends on the overall security of the user’s device and the app’s compliance with changing privacy regulations and standards.

4/ Cost Considerations in Voice Communication

VoIP solutions, commonly integrated into a business’s operations, may involve initial setup expenses, like acquiring specialized, hardware or software and IP Phones if required.  However, the long-term benefits, such as reduced call rates – especially for international communications – and the elimination of traditional telephony lines, can lead to substantial cost savings for organizations.

Conversely, WhatsApp calls offer a cost-effective alternative for individual users. They bypass traditional telephony networks by utilizing internet data, effectively eliminating call charges. For users with unlimited data plans or access to Wi-Fi, this can translate to minimal direct costs for voice communication. 

5/ Infrastructure Needed: 

VoIP often requires an advanced setup including SIP (Session Initiation Protocol) trunks or IP-PBXs (Private Branch Exchanges) for businesses, aimed at managing large-scale communication needs with reliability and flexibility. 

On the other hand, WhatsApp calls, while also utilizing VoIP technology, operate within a more streamlined and user-centric framework. These calls are conducted exclusively through the mobile application, relying on internet connectivity without specialized infrastructure.

6/ Protocol Used:

Protocols serve as the language through which data and, by extension, voice communications are transmitted. VoIP mainly functions using either the SIP or H.323 protocols. These protocols govern the management of voice, video, and message sessions on the IP network. 

Whereas, WhatsApp employs its unique end-to-end encryption with a transport layer security (TLS) protocol to secure its voice calls, showcasing its strong commitment to privacy and security.
