Technology Explained: VoIP vs WebRTC
Before diving into costs, it's crucial to understand what we're comparing. Both VoIP and WebRTC enable voice communication over the internet, but they use fundamentally different approaches that directly impact their cost structures.
Traditional VoIP Systems
How It Works:
VoIP converts voice calls into data packets and routes them through dedicated VoIP infrastructure. Requires specialized hardware, software, and ongoing service contracts.
Infrastructure Required:
- • IP phones or adapters ($50-300 each)
- • PBX server or cloud service
- • Network configuration and QoS setup
- • Professional installation and training
- • Ongoing maintenance and support
Cost Structure:
- • Monthly per-user licensing fees
- • Hardware purchase or lease
- • Installation and setup costs
- • Per-minute calling charges
- • Maintenance and support fees
WebRTC Technology
How It Works:
WebRTC enables real-time communication directly through web browsers. No additional software, hardware, or complex infrastructure required - just an internet connection and modern browser.
Infrastructure Required:
- • Any device with modern web browser
- • Internet connection (wired or wireless)
- • Built-in microphone and speakers
- • No additional hardware needed
- • Zero installation or configuration
Cost Structure:
- • Pay-per-use pricing only
- • No hardware costs
- • No installation fees
- • Ultra-low per-minute rates
- • No maintenance or support fees
