Researched and written by [Neeraja Prakash](https://research.g2.com/insights/author/neeraja-prakash)

Updated April 9, 2026

Voice over Internet Protocol (VoIP) software transmits phone calls over an IP network without relying on traditional telephone infrastructure, functioning as a modern alternative to private branch exchange (PBX) systems. It helps organizations cut communication costs, support remote work, and maintain secure calling capabilities.

### Core Capabilities of Voice over Internet Protocol (VoIP) Software

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

- Provide VoIP PBX systems for businesses or offer a VoIP softphone application
- Include features that help manage incoming calls, such as call forwarding, call transferring, and routing
- Enable real-time network monitoring via dashboards
- Offer integration compatibility with communication and CRM platforms
