Voice over internet technology allows users to make voice calls using an internet connection instead of traditional phone lines. Also known as VoIP, this innovation has revolutionised communication for businesses and individuals by offering crystal-clear audio, lower costs, and enhanced flexibility across devices and locations.
What Is Voice Over Internet?
Voice over internet refers to the transmission of voice signals over IP networks, enabling real-time communication without analogue phone lines. It’s the foundation of VoIP and is used in apps, business systems, and contact centres. KLR implements enterprise-grade VoIP services using reliable connectivity and managed infrastructure.
How It Works in a Business Context
VoIP converts your voice into digital packets and routes them through your business internet provider. You can make calls from IP phones, desktops, or mobile apps. It’s scalable, easy to use, and works perfectly for remote or hybrid teams. Read our comparison of VoIP and landlines to explore advantages further.
Benefits of Voice Over Internet
This technology offers lower call rates, excellent audio quality, multi-device access, and features like voicemail-to-email, conferencing, and auto-attendants. With hosted voice over IP, companies can avoid PBX hardware and enjoy cloud-based calling with minimal overheads.
Required Infrastructure for Success
To use voice over internet effectively, you need fast and stable connectivity—preferably fibre or a dedicated leased line. KLR provides networking equipment, IP telephones, and end-to-end support to ensure smooth deployment.
Security Considerations
Internet voice systems require protection from interception, spoofing, and DoS attacks. KLR integrates firewalls and security policies into all VoIP deployments. Using VPNs, encryption, and managed routers, we ensure safe and compliant voice communications.
Applications for Home and Business
Voice over internet is used in both residential and commercial setups. Businesses rely on it for high-volume calling and CRM integration, while individuals benefit from lower international call rates and app-based calling. Our IT support team helps configure and maintain both environments.
Testing, Maintenance, and Support
Reliable performance requires structured cabling, bandwidth management, and diagnostics. KLR technicians use tools like a network cable tester or LAN tester to eliminate bottlenecks and ensure optimal voice traffic flow.
