VoIP is a cloud-based system connecting your team’s existing mobile devices, computers, and desktops. It converts analog sound frequencies into digital data transmitted instantly over the Internet.

Businesses looking for more features and scalability should consider switching to VoIP phone systems. However, there are a few things to remember before making the switch.

Call Quality

Regarding sound quality, VoIP can provide a small advantage over landlines. However, the difference depends on your internet connection. VoIP calls can be virtually indistinguishable from landlines with a high-quality internet service provider. VoIP’s main disadvantage is that it relies on an internet connection, which means a power outage will disrupt the phone system. Furthermore, the location of an internet call can’t be easily tracked, which can slow emergency responders. Overall, VoIP is 40-80% less expensive than landlines and offers many benefits to businesses. It also has low maintenance and setup costs, enabling enterprises to scale quickly.

Additionally, it allows employees to work from any location with an internet connection. The technology is constantly evolving, and the future of business communications looks bright. With so many benefits of an internet home phone, it’s no wonder more businesses and even residential homes are switching to VoIP. 


For VoIP to work properly, you’ll need a reliable internet connection. It’s worth checking with your IT team to ensure that your business’s Internet meets the minimum requirements for a quality VoIP system. VoIP technology uses a variety of wideband audio codecs that provide higher-quality sound during calls. It also enables features like virtual receptionists, voicemail-to-email, three-digit dialing, and more. On the other hand, landlines typically come with basic calling features and charge extra for advanced services like call recording. Another benefit of VoIP is that it doesn’t require the same infrastructure as landlines, including hubs, switches, telephone adapters, lines, and copper wires connecting to the PSTN. It can be a significant cost saver for businesses looking to cut costs. It’s also far easier to scale VoIP as a company grows than with an analog phone system. It’s a better choice for fast-growing businesses.


VoIP technology is a cloud-based solution that doesn’t require copper wires and hardware. Instead, it uses your existing internet connection to power your business phone system. It offers clear advantages over landlines, including lower costs, improved mobility, and increased security. As a result, many businesses are moving away from landline systems and adopting VoIP solutions for their communications needs. Some leading VoIP providers offer a wide range of advanced calling features for an affordable monthly fee. A traditional landline system can be expensive to scale as your company grows.

In contrast, a VoIP business phone system can easily support more employees or locations with a few clicks. Some VoIP services (including Dialpad) also include call screening and blocking functionality to help reduce those pesky spam calls. This way, only legitimate customers can get through to your team. It is a huge time saver for your business. In addition, VoIP is more resilient to outages as it doesn’t rely on a physical line.


Landlines have a slight edge regarding emergency calls, but VoIP wins in almost every other way. For instance, a high-speed internet connection is essential for VoIP service, and most providers offer multiple packages to ensure businesses have the capacity needed. A Hosted Private Branch Exchange (PBX), a physical infrastructure required for a landline business system, can be expensive for organizations to set up and maintain. On the other hand, a VoIP solution offers various features such as virtual receptionists, voicemail-to-email, automatic call forwarding, and three-digit dialing that landline systems cannot provide at the same price point. Furthermore, VoIP systems include HD voice technology that translates sound waves into digital signals for the best possible audio quality. It enables telemarketing teams to deliver crystal-clear audio and increase productivity. Most of these VoIP systems have reporting and analytics tools unavailable on landline phones.
