Independently Verified

The Numbers
Don't Lie

Every claim we make is backed by independent testing from Broadband-Testing — Europe's foremost independent network testing facility — using Spirent Axon traffic generators and iTrinegy WAN emulators.

Voice Quality Under Extreme Load

8Mbps emulated WAN link, 500 FTP sessions + 500 HTTP sessions running simultaneously. Then we added voice calls.

Without ViBE — 6 Calls

  • MOS: 3.4
  • Packet loss: 4.4%
  • Latency: 225ms

    • With ViBE — 6 Calls

  • MOS: 4.0
  • Packet loss: Zero
  • Latency: 5ms

    • Without ViBE — 40 Calls

  • MOS: 3.1
  • 1,933 dropped packets
  • Latency: 211ms

    • With ViBE — 40 Calls

  • MOS: 4.0
  • 5 dropped packets
  • Latency: 7ms

    • Without ViBE — 80 Calls

  • MOS: 3.1
  • 14,817 voice packets lost
  • 127 of 160 calls successful

    • With ViBE — 80 Calls

  • MOS: 4.0
  • Flawless quality
  • 160 of 160 calls successful

    • Without ViBE — 180 Calls

  • MOS: 3.0
  • 200 successful calls
  • Severe degradation

    • With ViBE — 180 Calls

  • MOS: 4.0
  • 360 of 360 calls successful
  • All 180 HTTP sessions successful

    • The Ultimate Test

    180 calls at 50% bandwidth (4Mbps) — ViBE still delivered MOS 4.0, 360/360 calls, and all HTTP sessions completed successfully.

    TCP Acceleration Testing

    Raw Speed Comparison

    100Mbps symmetric link, 100ms RTT. Standard TCP vs ViBE.

    No Window Scaling
    TCP: ~5 Mbps
    ViBE: Near line speed
    0.1% Packet Loss
    TCP: 2x slower
    ViBE: Less than half the time
    1% Packet Loss
    TCP: Severely degraded
    ViBE: 25x faster

    Satellite + Packet Loss (500ms RTT, 0.1% loss)

    ViBE completed transfers approximately 7x faster than raw TCP.

    Aritari Voice Optimisation Testing

    The Headline Numbers

    10Mbps symmetric link, 40ms RTT. Real-world conditions.

    📞

    400 Calls on a Single Link

    Where 30 calls previously failed, ViBE carried 400 simultaneous calls with data capacity to spare. Ping RTT peaked at just 54ms.

    ⚡

    1-Second Failover

    Standard failover restored all calls in just over one second. With RAIN mode, calls were completely unaffected — zero interruption.

    🎯

    3 TCP Streams Kill 1 Call

    Without ViBE, just 3 TCP downloads alongside a single voice call on 10Mbps produced 1.8% packet loss. With ViBE — perfect quality with 10 calls, 10 downloads, and a 3Mbps UDP stream.

    📡

    ATM/DSL Transformation

    20 G.729 calls consumed ~6Mbps effective bandwidth due to overhead. With ViBE, the same link carried 400 calls with data capacity remaining.

    "

    Any company from SMB to ISP who wants to be able to optimise bandwidth consumed by a mix of VoIP and data should invest in Voipex's ViBE technology. It really is that much of a no-brainer.
