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

### 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.

### Insights from G2 on Voice over Internet Protocol (VoIP) Software

Based on category trends on G2, VoIP's reliability, cost savings, ease of remote access, and the convenience of softphone options that replace or supplement physical desk phones.
