Quality of Service (QoS)

It’s not just our quality of service. It’s your quality of experience.

Vonage can give you quality of service (QoS) for all your business communications including pristine, high-quality voice, video and messaging. Our goal is to maximize your communications efficiency and availability while eliminating call drops, data loss and static. We even can monitor for issues and fix them before you know they occur.

  • VoIP QoS for voice, video, conferencing and more
  • SD-WAN for UCaaS
  • 24/7 monitoring and updating

If your business relies on call quality, you need VoIP QoS

Will a garbled call lead to significant loss for your businesses? WIll a dropped call mean you lose a customer, the deal or your credibility? With Vonage you get VoIP quality of service on your office phone system.

What is QoS?

QoS stands for quality of service, and is an industry-wide set of standards and mechanisms used to ensure high-quality performance for critical applications which, in the case of a communications system, includes HD voice and video. Learn why quality of service is a true Vonage advantage.

Why Vonage for QoS

$600 million in new tech investments in just four years. 150+ U.S. patents (160+ pending). And a history of making network QoS work.

How can your business achieve QoS?

Voice or video data sent through a VoIP system is broken into thousands of data packets which travel through your network without the need or cost of a dedicated phone line. This data is reassembled as a call, conference, or video. QoS is achieved when unified communications have sufficient bandwidth, jitter is controlled, latency and data loss are reduced, and MOS is optimized.

  • What is latency or delay? The time it takes a voice packet to reach its destination is called latency or delay. Too much delay can exacerbate an echo on the line or cause parties to talk over each other.
  • What is jitter? Jitter is the variation of delay between packets. The human ear can handle consistent delay between packets but when the information jumps, we may hear garbled audio.
  • What is packet or data loss? Information packets can also be dropped. When this happens, data will be missing when it has being reassembled at its destination.
  • What is MOS? MOS (Mean Opinion Score) is a measure of how humans perceive the quality of the voice call calculated based on industry standard benchmarks including average latency, delay and jitter.
