Best VoIP Providers

Voice over internet protocol (VoIP) software uses the internet to transmit phone and video calls, effectively creating a unified network regardless of a worker’s location. One advantage of VoIP is that telephone calls via the internet don’t incur a surcharge beyond what the user is already paying for internet access, just like users don’t pay to send individual emails. Some VoIP applications come bundled with popular web browsers. Others are standalone products. Business-specific VoIP is commercial-class versions of residential VoIP services that provide small and medium-sized businesses with advanced features and functionality such as private branch exchange, conference calling, desk-to-desk calling, music on hold, and automated attendants. Most business and enterprise VoIP providers support multiple simultaneous calls.

To qualify for inclusion in the VoIP category, a product must:

  • Be able to share any or all: audio phone calls, video phone calls, pictures, screens, messages
  • Utilize the internet through both public and private networks
  • Be utilized across different (internal) communication channels as well as across differing platforms like web browsers and mobile applications.
