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

### Common use cases for Voice over Internet Protocol (VoIP) Software

VoIP software supports scalable, reliable communication for internal collaboration and customer-facing interactions. It also benefits teams using related tools such as [video conferencing software](https://www.g2.com/categories/video-conferencing), [UCaaS platforms](https://www.g2.com/categories/ucaas-platforms), [contact center software](https://www.g2.com/categories/contact-center), and [CRM systems](https://www.g2.com/categories/crm).

### How Voice over Internet Protocol (VoIP) Software Differs from Other Tools

VoIP differs from traditional PBX by replacing legacy on-premises telephony systems with IP-based calling, reducing infrastructure and maintenance costs while improving flexibility for remote and hybrid teams. Compared with broader UCaaS platforms, VoIP primarily focuses on voice calling, softphones, and SIP-based PBX functionality, though VoIP is typically a core component of most UCaaS offerings.
