Is VoIP Reliable for Business

While newer modes of communication like email and text messaging are undoubtedly essential, a dependable telephone system remains crucial for both internal and external business interactions. However, modern companies face new challenges with phone calls, such as the demand for flexibility, scalability, and international capabilities, among others.

These challenges partly explain why VoIP (Voice over Internet Protocol) business phone systems are gaining popularity. But is adopting a VoIP system the right choice for your small business? Keep reading to delve into VoIP and its reliability.

Do Businesses Adopt VoIP Phones?

In short, yes, businesses of all sizes frequently adopt VoIP phones. Why the shift toward this technology? VoIP systems offer increased flexibility, enabling businesses to make and receive calls wherever an internet connection is available. This is especially valuable considering the rise of remote and hybrid work arrangements. VoIP also provides several other advantages, including:

Lower average costs compared to traditional phone lines

Enhanced customer satisfaction through features like call routing, voicemail-to-email, and call analytics

Access to advanced features via Unified Communications as a Service (UCaaS)

For those unfamiliar with the technology, let's take a step back. A VoIP phone system utilizes the internet for call transmission. It converts audio conversations into digital packets, which are then transmitted through the internet in real-time. This differs from traditional landline systems that rely on physical telephone lines.

Fortunately, setting up a VoIP phone line is a straightforward process that often requires minimal new equipment, if any. Here's what you need:

Broadband or high-speed internet access: VoIP relies on internet connectivity, so a stable high-speed internet connection is essential. This can be in-office internet, home Wi-Fi, or mobile hotspots.

Internet-enabled devices: Any internet-capable device, from laptops to smartphones, can make VoIP calls.

VoIP adapters: These devices enable traditional phones and hardware to function as VoIP-enabled devices.

Is VoIP Reliable for Business?

Yes, VoIP is a dependable technology for business use. This is a common concern due to historical issues with internet reliability affecting call quality. However, VoIP is now highly reliable. You need access to high-speed broadband internet and reliable internet-enabled devices, as discussed earlier. Many businesses also implement backup power and internet sources to ensure system continuity during outages.

What makes VoIP reliable? Reliability for phone systems hinges on uptime and call quality.


VoIP uptime refers to how often a VoIP provider's service is available and operating as expected. For example, at Vonage, our uptime reliability averages 99.999% from July 2021 to February 2022. This ensures consistent VoIP access for users, unlike traditional landlines, which can suffer from hardware-related outages.

Call Quality:

High-speed internet connectivity typically ensures clear call quality with VoIP. Assuming a stable connection, you won't experience static or delays.

Backup Measures:

During power outages, internet access may still be available. ISPs often equip their lines with battery backups. Alternatively, consider:

Battery backups: Easily attach these to your router to maintain internet access during power outages.

Uninterruptible power supply (UPS): Combines surge protection with battery backup to instantly support devices during outages.

Portable generators: Provide power for extended outages.

For internet outages, options include:

Using mobile data

Employing a mobile hotspot

Using Wi-Fi USB dongles (internet sticks)
