Imagine a bustling business with offices scattered across different cities, each equipped with its traditional phone lines. The costs stack up quickly, from monthly bills to maintenance fees. Not to mention the sheer inconvenience of managing multiple services. Now, picture the frustration when modern communication demands, like video calls, instant messaging, and seamless call transfers, are out of reach.

This is where Voice over Internet Protocol (VoIP) is a game-changer for businesses. VoIP allows companies to make and receive calls via the internet, transforming the traditional phone system into a versatile, unified communications hub. It cuts down on the clutter of multiple landlines while slashing costs significantly.

Learn about the transformative benefits of VoIP for businesses, including how to set up VoIP or digital landlines for your business. 

What is VoIP, and how does it work?

VoIP (Voice over Internet Protocol) is a method of making phone calls through the internet, similar to Skype, Viber, and Google+. VoIP service has existed since 1991, allowing businesses to replace traditional phone lines, upgrade voice quality, access advanced calling features, and save on analog phone bills.

Which businesses are using VoIP?

VoIP is used worldwide by small to medium businesses and large corporations, primarily due to its cost savings and added benefits. With VoIP services valued at $151 billion in the US and forecasted to grow to $236 billion by 2028, it’s time to consider switching to VoIP—if your business hasn’t already. 

Key advantages of VoIP

  • No hardware installation fees
  • Reduced international calling rates
  • No need for separate phone lines
  • No maintenance required

Businesses can cut phone costs by 40–60% or more by switching to VoIP.  While the average traditional phone system costs about $50 per month, a second line with VoIP can cost as little as $4.96 per month.

Unlike traditional phone lines, which add charges like long-distance fees, maintenance, and other add-ons, VoIP covers unlimited calling, advanced features, and maintenance, so businesses get more for less. 

Felix Yanko, founding partner at Voiply, states that numerous businesses have witnessed transformative benefits from VoIP adoption. One such business is a local retail chain that cut communication costs by 50% while doubling customer engagement through integrated VoIP services. 

“All you need is a phone. We include the Voiply Mobile/Desktop App for free,” Yanko says.
“Our infrastructure is built in the cloud to be efficient, secure, and scalable, so we pass these savings directly to our customers.”

Unlike traditional phone systems that tie users to a specific physical location, VoIP allows employees to access their business phone system from anywhere with an internet connection. This is especially valuable for businesses with remote teams or a mobile workforce. Employees can make calls from their desktop in the office, a laptop at a café, or a smartphone abroad and continue to use their business phone numbers regardless of their physical location. 

Additionally, VoIP systems can easily integrate with other digital communication tools like video conferencing and cloud-based project management software, further enhancing collaboration among remote teams.

This ability to connect from anywhere, on any device, not only supports a better work-life balance but also opens up opportunities for businesses to hire talent from a broader geographic range. The flexibility to scale up or down based on business needs without significant infrastructure changes means businesses can stay agile in a dynamic market environment.

As companies expand, VoIP systems scale seamlessly to accommodate more users, additional locations, and increased call volume without additional infrastructure. This ensures businesses can grow without facing common bottlenecks associated with traditional phone systems, like limited geographic flexibility or extensive hardware upgrades.

Here’s how VoIP systems scale with businesses:

  • No physical infrastructure limitations: VoIP uses the internet, so expanding the system can often be as simple as adding new users to the software platform and ensuring sufficient bandwidth.
  • Cloud-based efficiency: Cloud providers can rapidly allocate additional resources to handle increased call volume or new features as a company grows. 
  • Software-based management and deployment: VoIP systems are managed via software, not hardware, simplifying the addition of new features or the integration of new technology. Software updates can deploy updates and new functionalities network-wide without physically altering a system.
  • Modular add-ons and integrations: A VoIP platform allows a company to start with a basic setup and expand its capabilities as its operational needs evolve.

Consider a mid-sized e-commerce company expanding to new regions and hiring remote customer service representatives. VoIP enables seamless integration with their CRM, facilitating streamlined customer interactions. The system's scalability allows the company to add new lines and users effortlessly, supporting rapid growth without additional physical infrastructure or phone lines. This reduces communication costs yet enables the company to improve operational efficiency and customer service. 

VoIP also improves efficiencies, saving businesses time and money. For example, VoIP systems integrate with customer relationship management (CRM) software, email platforms, and enterprise resource planning (ERP) systems, among others. This reduces the need for separate systems, which not only saves on costs for separate platforms but also improves workflows and employee productivity.

“VoIP integrations streamline communication workflows and reduce manual data entry, significantly boosting productivity by allowing teams to focus on their core tasks,” Yanko explains. “Features like click-to-call, caller information pop-ups, and automatic call logging all work to enhance productivity team-wide.”

VoIP technology offers advanced features that traditional phone systems often lack. These advanced features are often unavailable or more costly in conventional phone systems. Advanced features include but aren’t limited to:

  • Auto-attendant
  • Call forwarding
  • Integration with CRMs
  • Voice-to-email transcription
  • Conference calling
  • Call analytics
  • Spam call blocking
  • Simultaneous ring
  • HD voice
  • Easy management and reporting

According to Yanko, among the most underrated VoIP features are advanced call analytics and voice AI integrations. “These can offer deep insights into customer behavior and automate routine interactions.”

Maintaining clear and reliable communication is crucial in today's competitive business environment. 

VoIP technology uses sophisticated compression algorithms that efficiently use bandwidth to deliver high-quality audio. These algorithms help reduce the amount of data that needs to be transmitted over the internet, thus minimizing loss and improving sound quality.

Modern VoIP systems have enhanced network infrastructure to prioritize voice traffic over other data types. This prioritization ensures that call quality does not suffer, even during periods of high data usage within the network, helping businesses maintain a professional image.

How to ensure your internet connection supports VoIP

Here are some tips to ensure that your business’s  internet connection supports high-quality VoIP service:

  • Ensure that your internet connection provides sufficient upload and download speeds to handle your VoIP call volume alongside other internet usage. VoIP calls typically require about 100 kbps per line for optimal quality.
  • Assess your network regularly for issues that could affect VoIP performance, such as bandwidth bottlenecks or outdated hardware. 
  • Configure your router with Quality of Service (QoS) settings.
  • Choose a reliable internet service provider with strong customer service and a track record of minimal downtime.
  • Consider setting up a secondary internet connection for redundancy. This can be invaluable in preventing service disruptions due to service provider issues or local outages.

VoIP systems incorporate several security features to safeguard sensitive business data.

VoIP services commonly use strong encryption protocols, such as TLS (Transport Layer Security) and SRTP (Secure Real-Time Transport Protocol), to encrypt data transmission between endpoints. This ensures sensitive information, such as client details or proprietary data, remain confidential.

VoIP systems also typically require user authentication to access the network and make calls, which helps ensure that only authorized users can use the service.

Dedicated VoIP firewalls and Session Border Controllers (SBCs) protect the network against external attacks. These tools manage and monitor voice traffic as it crosses the network border, helping to prevent cyber threats such as denial-of-service attacks.

VoIP security best practices

  • Do regular updates to address security vulnerabilities
  • Configure VoIP systems to disable unnecessary services and secure access points
  • Segment networks to prevent an attacker from easily accessing other critical business systems
  • Educate employees about security threats like phishing attacks and the importance of using strong, unique passwords.

Since VoIP systems are typically cloud-based, they enable employees to maintain contact with contacts from anywhere with an internet connection. In unexpected disruptions, business operations can continue with minimal downtime with features like automatic call rerouting.

As businesses increasingly adopt digital transformation strategies, VoIP is a key component in evolving communication technologies. 

Integrating AI with VoIP, for example, can transform customer service through advanced interactive voice response systems and chatbots to handle repetitive interactions. This technology also supports real-time language translation, making it easier for global businesses to communicate without barriers. Additionally, the growing Internet of Things (IoT) trend can integrate VoIP in new ways, such as enabling voice commands for various devices and systems across a business’s operations.

Encouraging businesses to adopt VoIP isn’t just about keeping pace with technology—it’s about staying ahead. Companies that embrace VoIP now will benefit from its scalable nature, enabling them to easily add new functionalities as they become available. This adaptability helps businesses stay competitive in a fast-evolving market. 

As remote work continues to be normalized, VoIP’s ability to support a distributed workforce becomes increasingly valuable. It provides a consistent and reliable way for teams to collaborate, regardless of location. This capability attracts and retains top talent who seek flexibility in their working environment.

Environmental benefits of VoIP

Traditional phone systems require extensive hardware, such as copper wiring and dedicated phone lines, which can have a significant environmental footprint. In contrast, VoIP operates over the internet, using existing network infrastructure, reducing the need for additional materials. 

VoIP systems also support remote work and virtual meetings, decreasing carbon emissions from business travel and commuting. By adopting VoIP, businesses can contribute to a more sustainable future.

Disadvantages of using VoIP for Business

While VoIP offers numerous advantages for business communications, businesses must consider some disadvantages when transitioning from traditional phone systems.

Dependence on internet connectivity

One of the main drawbacks of VoIP services is their reliance on a stable and fast internet connection. This means any disruption in internet service directly impacts service availability. Bandwidth limitations can cause poor audio quality, dropped calls, and delays. Because of this, businesses should invest in backup internet connections—especially in areas where internet services might not be reliably fast or stable.

Power outages

Unlike traditional phone systems that can operate during power outages using the power provided through telephone lines, VoIP systems require power for the internet and phone hardware (if applicable). This can pose a risk to businesses in regions prone to power outages.

However, with VoIP, you can set up call forwarding to a cell phone or another live number so that your calls will still go through during a power outage. 

Integrate VoIP into your business communications with Voiply

Adopting VoIP is a strategic decision that equips businesses to be resilient, adaptive, and competitive.

VoIPly stands out as a premier VoIP provider. Choose from a mobile app with a second business line for solopreneurs, small business solutions for app-only teams, and hardware-compatible digital landlines for those who prefer or require physical handsets.
