Voice Quality
Guaranteed
ViBE was born in the service provider world. For over 17 years, ITSPs across South Africa and globally have relied on ViBE to deliver voice quality that their customers demand — over connections that shouldn't be able to support it.
Why More Bandwidth Isn't the Answer
A single G.729 voice call needs just 8kbps of payload. But by the time IP, UDP, RTP, and link-layer headers are added, that 8kbps becomes 34kbps on an ATM/DSL link. That's over 400% overhead.
Now add data traffic. Just three TCP streams alongside a single voice call on a 10Mbps link produces 1.8% packet loss and 50ms+ jitter. On a 10Mbps link. With one call.
The problem isn't bandwidth. It's how IP networks handle real-time traffic alongside everything else. ViBE solves this at the protocol level.
The Overhead Problem
ViBE removes redundant headers using proprietary methods, reducing bandwidth per call by up to 80%.
What ViBE Delivers for Service Providers
Massive Call Density
Carry 400 simultaneous calls on a link that previously couldn't manage 30. ViBE's header removal and byte-level QoS transform what's possible on any connection.
Guaranteed MOS 4.0
Independent testing confirms MOS 4.0 maintained with 80+ concurrent calls on an 8Mbps link — with data traffic running simultaneously. Zero packet loss.
80% Bandwidth Reduction
Proprietary header removal reduces the bandwidth each call consumes by up to 80%. More calls on less bandwidth means better margins and happier customers.
Seamless Failover
Calls survive link failures. Standard failover restores in about one second. RAIN mode provides zero-interruption failover — users never notice.
Real-Time Monitoring
Full visibility into the true underlying status of your network. Call access control, traffic statistics, and quality metrics — all in real time.
Zero-Touch Deployment
Our Task Manager platform enables mass deployment with minimal user involvement. API integration with your existing provisioning systems for seamless onboarding.
Proven at Scale
Built for the Voice Business
Voipex started in the South African ITSP market, where bandwidth was expensive and unreliable. We had to make every byte count — and we did. That DNA runs through everything ViBE does today.
From there, ViBE expanded into the global termination market, where voice quality improvement and the ability to maintain call quality across challenging international routes proved invaluable.
Today, our service provider customers span multiple continents, carrying millions of minutes over ViBE-optimised connections every month.
Transform Your Voice Quality
Whether you're an ITSP, carrier, or UCaaS provider — ViBE can dramatically improve your call quality while reducing your bandwidth costs.
