A 2015 report VoIP fraud call analysis from Simwood highlights that telecommunication fraud cost customers more than US$ 46 billion annually. And since there is no way to trace IP phones, more and more scammers rely on them to extort customers.

Also, BusinessWire reports that 95% of all customer interactions will be powered by AI, suggesting that existing call handling, and auto attendees features will further revolutionize and improve VoIP processes.

At the same time, the rise of remote work, especially since the pandemic, indicates that businesses cannot rely on their on-premise phone system anymore.

Nevertheless, Millennials and Gen-Xers prefer messaging and video chats more than phone calls. Additionally, businesses realize the benefits of video communications, given it reduces handle time by 70%. Plus, it has a close rate of 35% to 75%.

Needless to say, video technology is giving tough competition to VoIP (although the VoIP technology is growing). WebRTC technology — real-time communication in a browser using APIs — will merge with VoIP to bring a more seamless communication system.

Still, many businesses' ever-increasing demand for UCaas and mobile UCaaS will increase VoIP use among businesses. And the rise of mobile phone preference among businesses suggests the increase in mobile VoIP users.

What Do These VoIP Statistics Mean for Your Business?

Additionally, its ability to integrate with other software like ecommerce CRM tools are helping businesses store, organize, and analyze data related to consumer interactions conveniently.

So, if your company still hasn’t upgraded from a traditional phone line to VoIP systems, now is the time to choose the best business phone service and move to a more reliable and flexible system that makes your communication system intelligent.
