What is VoIP, and How Does it Work?

Voice Over Internet Protocol, VoIP, is a phone service that operates over the internet allowing anyone with an internet connection to make and receive calls. 

Compared to a traditional telephone network, VoIP allows for a feature-rich communication experience equipping businesses with video and messaging all on the same platform. 

VoIP works using IP-based networks instead of the PSTN (public switched telephone network) system used for traditional phone lines. 

A VoIP system can make and receive calls through IP-based networks just like that of a traditional phone line. The difference is that it can also include multiple other features and desired integrations that streamline communication across teams and locations. 

What to Consider When Choosing a VoIP Service

VoIP providers have quickly become a popular choice among small and large businesses for their functionality as multiple device communication platforms. The versatile solutions offered by VoIP providers allow sales, marketing, and customer service teams to increase productivity and efficiency, helping their businesses grow and thrive. 

When searching for a VoIP provider that will fit seamlessly into your business, be sure to consider the following questions:

  • What are the pricing and plans offered?
  • Do they offer a mobile app?
  • Do they integrate easily with existing applications, for example Salesforce?
  • What are the call management features they offer?
  • Do they offer customer support? In what form?
  • Is their security system robust?
  • Is there an opportunity for it to grow with your business?
  • Do you need a VoIP softphone or SIP hardware?

Keep those questions in mind while you explore the list below, outlining the best business VoIP providers and phone services.
