How does Mobile VoIP technology work?

Although the process behind mobile VoIP calling may seem complicated, it works instantly. Mobile VoIP is used to convert your voice into digital packets, which are then transmitted across the internet.

Here’s a simple breakdown:

The working steps of mobile VoIP technology.

1. Voice to Data Conversion

The mobile VoIP app on your phone records your voice when you are talking. It then directly translates the analog sound waves into small digital data packets. These packets are compressed to make them efficient and facilitate fast internet travel.

The app records such sound waves and converts them to a stream of digital data using an Analog-to-Digital Converter (ADC). But this raw data is too large to transmit efficiently. This is where a codec comes in.

?

What is a Codec?

A codec is an advanced algorithm that compresses the digital voice data. The compression is relevant for maintaining good voice quality.

2. Transmission over the Internet

The compressed data packets are then sent over your active internet connection. This could be your Wi-Fi connection or your mobile data plan (4G/5G). Unlike a traditional landline, which creates a dedicated, single path for a call, the internet uses a method called “packet-switching”.

Each data packet is addressed individually, and the most efficient path is taken. The packets may even be routed along different paths to the same destination, which is a highly efficient method of handling network traffic.

3. Routing by the Provider

The data packets travel to your VoIP provider’s servers. These servers act as a digital switchboard, routing the call to its destination. The call is either connected directly to another VoIP user over the VoIP network, or it is transferred to the traditional telephone network to reach a landline or mobile number.

  • VoIP-to-VoIP Call: If you are calling someone who is also using a VoIP service, the packets will be forwarded directly to them over the Internet. These calls are often free as they never go through the traditional phone network.
  • VoIP-to-Traditional Call: When you are calling a regular landline or mobile number, the packets are directed to a PSTN (Public Switched Telephone Network) gateway by the provider. The gateway will serve as a translator, converting the VoIP data packets back into a format that the old network can comprehend.

4. Reception

The recipient device receives the incoming data packets, reassembles them in a correct order, irrespective of any jitter. This ensures that the call is not choppy, caused by network delays.

And finally, the VoIP service or phone then decompresses it and reorders the packets into their original order. It then converts the digital transmission back again into audible, clear sounds and enables one to have a real-time conversation.

How to Set Up Mobile VoIP?

Mobile VoIP is very easy to begin, and no technical background is required. With a few simple steps, you can get your new phone system running in no time with a smooth and efficient transition.

Prerequisites for Setting up Mobile VoIP

Before choosing a provider and installing an app, it is necessary to ensure that the foundation is in place. These easy requirements will ensure that you have a smooth setup and a premium quality call.

I. Compatible Smart Device

The first thing you require is a modern smartphone or tablet. Mobile VoIP services run on apps that are compatible with the current systems. This will cover the iPhone and smartphones. This requires you to be able to access the App Store or the Google Play Store.

II. Stable Internet Connection

This is the most essential element for clear and reliable calls. VoIP services need the internet, and the quality of the calls will depend on the speed of your internet connection.

You have the option to use one of the following:

  • Wi-Fi: Nothing can beat the quality of the audio when you have a stable and reliable Wi-Fi connection, whether at home or at the office.
  • Mobile data: You need to be able to access a reliable 4G LTE or 5G connection on the move. A weak cellular signal can lead to choppy audio or dropped calls.

III. A Headset

A headset (wired or Bluetooth) is not required strictly, but highly recommended. It improves the call quality by reducing background noise and distracting echo that may occur when using a speakerphone.

Setting up Mobile VoIP: Step-by-Step Guide

Here is a step-by-step guide that can help you select a provider to make your first phone call.

  • Step 1: Select a Provider

Research different VoIP providers. Compare VoIP companies. Compare their features, pricing, and calling plans to determine which one best suits your business.

  • Step 2: Select a Plan and Number

Sign up for a subscription plan. You can request a new business phone number or choose to transfer (port) your existing number to the new service.

  • Step 3: Download the App

Visit your App Store or Google Play Store. Then, install the official VoIP app from your provider onto your mobile phone.

  • Step 4: Configure Your Settings

Sign up with your new account details. Set up business hours, voicemail greeting, and call forwarding rules. Once done, you can start making calls.

Mobile VoIP Vs. Traditional Cellular Services

To compare communication options, it is necessary to mention the major differences that exist between mobile VoIP and traditional cellular services. Both can be used to make calls over a phone, but differ depending on various technologies and in terms of cost, utility, and flexibility.

Now, to get a feel of which one will suit you better, let us discuss the differences.

A. Key Differences in Technology and Functionality

Mobile VoIP uses the internet (a packet-switched network) to make calls. It converts your voice into digital data packets and transfers them over a Wi-Fi or mobile data connection.

Traditional Cellular is based on cellular towers or circuit-switched networks. This technology provides a dedicated and constant link between the two callers throughout the conversation.

Cost Comparison

Mobile VoIP is affordable, especially on long-distance and international calls. These calls are usually much cheaper or even included in the package.

When comparing costs, VoIP phone calling is almost always more economical, especially for businesses. Traditional Cellular can be costly, with higher charges for international calls. It also comes with high roaming charges when you use your phone outside of your provider’s coverage area.

Feature Set Comparison

Mobile VoIP has advanced features like auto-attendants, call recording, voicemail-to-text transcription, and other business software such as CRMs.

Traditional Cellular is focused on an individual consumer basis and offers basic texting and calling features. Advanced business features are usually not available or come at an extra cost.

Let’s summarize the major differences between the two with this quick table:

Aspect Mobile VoIP Traditional Cellular
Technology & Functionality Uses the internet to make calls. Relies on cellular towers.
Cost Cost-effective, particularly for long-distance and international calls. It can be expensive, with higher charges for international calls.
Feature Set Includes advanced features like auto-attendants, call recording, and voicemail-to-text transcription. Offers basic calling and texting features.

Which Industries Can Benefit from Mobile VoIP?

The flexibility and innovative features of mobile VoIP make the technology useful in all business lines. A business where the process of communication plays a substantial role, and employees value mobility, can experience improvements in its operation and customer service.

Let’s explore some key industries that can benefit the most from mobile VoIP solutions.

I. Healthcare

In healthcare, mobile VoIP enhances secure and efficient communication for telehealth services and patient follow-ups. Doctor and nurses can use their personal phones without revealing their private numbers, and this shift can ensure them privacy and professionalism.

However, to ensure that patient data is protected, you need to select a HIPAA-compliant service.

For example, a nurse can make calls to patients with a business number via a secure VoIP app on a personal phone. This keeps both her personal and patient data safe.

II. Real Estate

To a real estate agent, who is constantly moving around, a mobile VoIP app is a must-have. It also allows them to do business calls together with personal calls without the need to reveal their personal numbers on a single mobile handset. They can answer calls to their business number wherever they are, whether at a property showing, in their car, or at their office, ensuring they never miss a lead.

For example, an agent uses a VoIP auto-attendant to professionally route buyer inquiries from a “For Sale” sign, ensuring no leads are missed during a showing.

III. Retail and E-commerce

Retail and E-commerce enterprises can experience enormous advantages. The ability of customer service teams to handle calls from anywhere, using VoIP systems, makes mobile VoIP a great way of supporting remote working.

Features like call queues and call analytics help in managing high call volumes and improve customer experience, which increases the satisfaction and retention rates.

For example, an online store can have its customer service team working remotely and attend the business phone line wherever, reducing the response time during holidays.

IV. Technology

VoIP is affordable and flexible, making it suitable for tech startups and small businesses. It provides a professional, fully functional phone system at minimal investment in hardware or a traditional phone system.

As the business expands, adding new users can be as simple as updating a subscription, offering a communication solution that grows with the business.

For example, a small tech startup uses a VoIP auto-attendant (“Press 1 for Sales”) with the aim of presenting an image of a larger and established entity to the client.

V. Consultants and Freelancers

Mobile VoIP is immensely valuable to consultants and freelancers. It offers a dedicated business line on a personal mobile phone, which makes it a good tool to create a separation between work and personal life.

Such a professional setup will increase credibility with clients and make managing business communications much easier.

For example, a freelance designer uses business hours in their VoIP app, which redirects after-hours client calls to a professional voicemail.
