VOIP vs. VOLTE: What Suits Your Business Most

volte vs voip for business

VOIP (Voice Over Internet Protocol) and VOLTE (Voice Over LTE) are two popular communication technologies that allow businesses to make phone calls over the Internet. While they share some similarities, they also have key differences that can make one more suitable than the other depending on your business needs.

With so many options available, it can be difficult to know which one to choose. In this article, we’ll break down the differences between VOIP and VOLTE and help you determine which one is the best fit for your business.

Main Differences Between VOIP and VOLTE

One of the main differences between VOIP and VOLTE is the network they use. VOIP uses the internet, while VOLTE uses 4G LTE networks. Another difference is the devices they can be used on. VOIP can be used on any device with an internet connection, while VOLTE requires a device that supports 4G LTE networks. Moreover, VOLTE provides better call quality, faster call setup times, and improved battery life compared to VOIP.

Advantages of VOIP


Cost savings

VOIP typically costs less than traditional phone systems because it uses internet connections instead of traditional phone lines. This can result in significant cost savings for businesses, especially those that make frequent long-distance or international calls.


VOIP allows users to take their phone numbers with them wherever they go, as long as they have an internet connection. This means that businesses can have a virtual presence in multiple locations without needing physical offices.


VOIP systems offer a wide range of features that aren’t available with traditional phone systems, such as call forwarding, voicemail to email transcription, video conferencing, and more. These features can improve communication and collaboration within a business.

For example, there are services such as Optimum Business that offer feature-rich packages so you can stay connected to your customers. All you need is an Optimum Business phone number to start connecting with more leads and nurture your current customer base.


VOIP can easily scale up or down depending on the needs of a business. Adding or removing lines can be done quickly and easily without the need for additional hardware or infrastructure.


VOIP allows users to make and receive calls from anywhere with an internet connection. This means that employees can work remotely or on the go without being tied to a physical office.


VOIP systems can be easily integrated with other business applications, such as customer relationship management (CRM) software, to improve productivity and streamline communication.


The quality of VOIP calls has improved significantly in recent years, with many providers offering high-definition audio and video calls. This means that businesses can rely on VOIP for high-quality communication with customers and colleagues.

Disadvantages of VOIP

internet connection

Dependence on Internet Connection

VOIP relies on a stable and strong internet connection. If the internet connection is weak or unreliable, call quality may suffer, causing dropped calls, choppy sound, or delays.

Power Outages

Unlike traditional landline phones that work even during power outages, VOIP phones require electricity to function. If there’s a power outage, the VOIP phone system won’t work unless there is a backup power source.

Security Concerns

VOIP calls are vulnerable to hacking and eavesdropping, which can lead to sensitive information being compromised. Companies need to take extra precautions to ensure that their VOIP systems are secure.

Latency Issues

VOIP calls transmit voice signals over the internet, which can lead to latency issues. Latency refers to the time delay between when a speaker speaks and when the listener hears the message. This can be frustrating and cause misunderstandings in conversations.

Compatibility Issues

VOIP technology isn’t universally compatible with all devices and software. Some older devices may not support VOIP, and some software may not work well with VOIP systems.

Emergency Services

VOIP systems don’t always support emergency services like 911 in the same way that traditional landlines do. This can be a critical disadvantage in emergency situations where immediate access to emergency services is needed.

Advantages of VOLTE

LTE network

High-Quality Voice Calls

VOLTE provides superior voice quality compared to traditional voice calls, as it uses a high-speed data network to transmit voice calls. This means that calls are clearer and have less background noise, making it easier to hear and understand the person you’re talking to.

Faster Call Setup

With VOLTE, calls are set up much faster than traditional voice calls, which means that you can connect with your contacts quickly and easily. This is particularly useful in emergency situations where every second counts.

Seamless Call Handover

VOLTE allows for seamless call handover from LTE to Wi-Fi networks, which means that you can continue your call even if you move out of LTE coverage. This is particularly useful if you are in an area with poor network coverage, as you can switch to Wi-Fi and continue your call without interruption.

HD Video Calls

VOLTE supports HD video calls, which means that you can make high-quality video calls to your contacts. This is particularly useful for business calls, as it allows you to have face-to-face conversations with your colleagues and clients, even if you’re not in the same location.

Simultaneous Voice and Data

VOLTE allows you to use voice and data services simultaneously, which means that you can browse the internet, send messages, and make calls at the same time. This is particularly useful if you need to access information while you are on a call.

Enhanced Security

VOLTE uses end-to-end encryption to protect your voice calls from eavesdropping and hacking. This means that your conversations are secure and private, which is particularly important for business calls where sensitive information may be discussed.

Disadvantages of VOLTE

battery life

Dependence on Internet Connection

One of the major disadvantages of VOLTE is it requires a stable and reliable internet connection to function properly. Poor internet connectivity can lead to dropped calls, poor call quality, and even complete call failure.

Battery Life

VOLTE requires more power than traditional voice calls, which can drain the battery life of the device faster.

Limited Compatibility

VOLTE is not compatible with all devices, and some older models may not support the technology, meaning that users may need to upgrade their devices to use VOLTE.

Network Coverage

VOLTE requires strong network coverage to function properly. It may not work in areas with poor network coverage or in remote locations where network coverage is limited.

Increased Data Usage

VOLTE uses data to make voice calls, which can increase the amount of data usage on a user’s plan. This can be a disadvantage for small businesses on a limited budget.

Final Thoughts

The choice between VOIP and VOLTE will depend on your company’s specific needs. Ultimately, the choice of whether to use VOIP or VOLTE should consider factors such as price constraints, coverage area needed, and desired features of the system as well as what kind of voice services are most important for your business.
