Best VoIP Providers

Voice over internet protocol (VoIP) software uses an IP network to transmit phone calls, and in some cases video calls and other messaging, seamlessly without the need to connect to an extra network. It is a modern form of PBX, short for private box exchange or private branch exchange, a broad term for private telephone networks within organizations. Businesses can utilize VoIP solutions to have a reliable means of voice-based communications that leverages a pre-established internet connection, enabling calls between workers on the same network and to external clients or vendors. For organizations with a complete VoIP system, the technology can be utilized by employees at every level for their basic communication needs. These solutions save the company and its employees money and hassle related to standard phone hardware and membership plans, providing base level call features along with select other helpful features depending on the service.

VoIP is integrated collectively into company systems and users can often access features through a plug-in on their web browsers or by connecting to the network through a personal phone using the internet connection rather than wireless network. Depending on the VoIP provider, it may work in conjunction with specially designed hardware or be hosted in the cloud and not require additional hardware. VoIP software may integrate with other platforms such as CRM software to give users easy access to important customer information during calls, or web conferencing software to add increased functionality for multi-user video meetings. Conferencing tools will occasionally allow attendees to utilize their VoIP connections for optimum performance and call quality. Certain VoIP solutions offer features of web conferencing and team collaboration software, such as multi-way video chats and instant messaging, but only within the established network.

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

  • Transmit voice over the user’s IP network to be received on a separate computer or device
  • Utilize the internet through both public and private networks
  • Allow varying numbers of calls at the same time with no interruption
  • Allow users to bypass landline connections or wireless networks on company or personal devices to tap into the unified network
