VoIP Basics: Complete Guide to Affordable Business Calling

Traditional phone systems are costly, rigid, and lack the features modern businesses need, especially for remote work. This is a significant problem that stifles growth and flexibility.

The solution is Voice over Internet Protocol (VoIP). This technology utilizes an existing internet connection instead of outdated analog lines to transmit calls, offering significant cost savings and superior quality. 

This means, VoIP offers the crucial flexibility that businesses need to remain competitive on a global scale.  According to a recent industry report, the global VoIP market is expected to grow from $134.86 billion in 2023 to $151.21 billion in 2024, representing a compound annual growth rate (CAGR) of 12.1%. 

If you are considering switching from your traditional phone system to VoIP, this guide will help you understand the basics of VoIP, its benefits, and how to set it up. 

Overview of Voice over Internet Protocol (VoIP)

Voice over Internet Protocol, or (VoIP), is a technology that enables you to make low-cost phone calls using the internet instead of traditional phone lines. Think of it like the difference between mailing a physical letter and sending an email. 

In a traditional letter, you need to have a postal infrastructure (mailboxes, postmen, sorting facilities, delivery trucks) to send a message from one point to another. However, email can travel quickly over the internet, arriving within seconds, regardless of distance. 

VoIP works similarly but for phone calls: instead of relying on dedicated copper telephone wires, your voice is transmitted as digital data packets over the internet, just like an email or a video stream.

VoIP Types

Businesses typically have two options for implementing VoIP: on-premise PBX or hosted (cloud-based) PBX. Both systems utilize Private Branch Exchange (PBX), but they may differ in terms of their setup, management, and responsibilities.

On-Premise PBX

In an on-premises PBX, all the hardware and equipment which are needed to make VoIP phone calls are kept in your office. Here, calls are made through IP phones that connect to an IP-PBX serves with the help of a local network. 

Hosted (Cloud-Based) PBX

The hosted PBX is managed by a third-party provider that handles all its tasks, including hardware, setup, and maintenance. With this, you can get instant setup and deployment of your features. 

VoIP terminology 

Voice over Internet Protocol (VoIP) utilizes various industry-standard protocols and codecs to ensure reliable call completion and high-quality sound. Here are some key technical terms associated with VoIP:

• Audio codecs: These VoIP codecs determine the method by which your voice data is compressed, transmitted, and ultimately perceived on both sides of the call. Some of the known VoIP codecs are G.711, G.722, and G.729.
  
• Session Initiation Protocol (SIP): A protocol used to start, maintain, modify, and terminate the VoIP sessions in real-time with each connection. The SIP is used when both endpoints communicate via video, message, or voice. 
  
• Public Switched Telephone Network (PSTN): In VoIP, PSTN represents the traditional, circuit-switched telephone infrastructure being replaced by IP-based services.
  
• Jitter: Jitter refers to the variation in the time it takes for data packets to travel from the sender to the receiver. High jitter can cause noticeable delays, often experienced by users as “lag.”
  
• Dynamic Host Configuration Protocol (DHCP): DHCP enables client devices on a network to automatically obtain an IP address, along with other essential settings required to establish a connection. It also prevents duplicate IP addresses. VoIP phones can operate using either a static or dynamic IP configuration.
  
• Latency: Latency is the delay between sending a signal and it reaching the receiving endpoint. Essentially, it measures the time it takes for a user’s voice to be transmitted and heard by the other party.

How to set up a VoIP network for your business

To set up a VoIP (Voice over Internet Protocol) network for your business, begin by assessing your specific communication needs and setting a budget.

Here’s a step-by-step guide on how to get started with a voice over IP phone system: 

Step 1: Understand your business needs

Before setting up VoIP, it is essential to have a clear understanding of why your business needs a business VoIP phone system. So, identify the key purpose of using it, and then determine the number of users using it, the call volume necessity, or the need for remote working. 

You also must determine its scalability for future business growth, feature expansion, flexible plans, cloud-based platforms, and modular hardware.
