What Is VoIP?

VoIP allows you to make phone calls with a broadband internet connection (like Wi-Fi) rather than a typical, analog telephone line. It works by converting your voice into a digital signal that's passed through the internet, and doesn't require a traditional phone for a voice call.

VoIP calls can occur from VoIP phones, computers, or phone adapters. The digital signal can travel straight to another computer or VoIP phone, or convert into a normal telephone signal if contacting an analog telephone. 

There are many advantages to using VoIP over traditional phone services. Here are three core reasons to consider adopting a VoIP call center phone system:

1. Lower Cost

At Verizon, a traditional, unlimited mobile plan ranges from $40 to $60 for four lines per month. A landline home plan starts at $79.99 per month. A business VoIP plan starts at $35 per line per month for one to ten lines and can go as low as $25 per line per month for 21+ lines.

Clearly, you can see the difference in price between an analog phone plan and VoIP phone service. Many companies have made the shift due to this cut in cost for communications.

In many cases, VoIP can even be free. After all, if you have a computer, microphone, speaker, and WiFi connection, you can likely find and use a free VoIP service.

2. Better Features

VoIP phone service offers all the same features included in your traditional phone plan: voicemail, caller ID, call forwarding, three-way calling, and more. Plus, it offers even more features, such as the convenience of being able to connect these features to a computer or other device. Your employees can take or make calls and listen to voicemails straight from their computer, laptop, or tablet.

3. Video Calls

VoIP hit peak popularity back in 2003 when Skype was founded. This app allows you to make video conference calls and phone calls and share instant messages. The ability to use these services for free was revolutionary and a key aspect of VoIP that cannot be accomplished by traditional phone services.

VoIP Can Be a Game Changer for Your Business

As businesses continue to transition to remote and hybrid work environments, having a reliable and flexible telecommunications solution becomes increasingly important. 

VoIP solutions provide businesses with a range of communication tools, including voice and video calling, text messaging, and conferencing, all within one streamlined platform. They also offer businesses greater flexibility and scalability and cost savings since they don’t require hardware costs like traditional telecom solutions.
