A VoIP high quality check measures the efficiency of your community connection. The check simulates a set variety of calls in your community and makes use of key metrics to find out how calls would sound in several conditions.
It might probably enable you perceive whether or not your connection is powerful sufficient earlier than implementing a VoIP system and provide you with a warning to potential submit deployment points as properly.
Imply opinion rating (MOS) is an trade customary metric for VoIP name high quality — it’s a easy 1-5 ranking system with 1 being the worst and 5 being one of the best.
Something above a 4 is adequate and scores beneath 3.5 ought to be thought-about unacceptable. Beneath that vary, customers usually tend to expertise mic echo, dropped calls, uneven or robotic sounds, and chopping out.
This information covers all the pieces it’s worthwhile to know to carry out VoIP exams and tweak settings to optimize for MOS.
What a VoIP high quality check measures
Earlier than we dive into the right way to run a VoIP high quality check, it’s necessary to know what metrics you’ll get again and what they imply.
Each VoIP check is completely different, however most measure issues like:
- Add and obtain velocity — Measures how briskly information packets can transfer by way of your community. Basically, the upper the velocity, the higher the standard.
- Bandwidth — The utmost quantity of knowledge that may be transmitted throughout your community. It immediately impacts the variety of simultaneous calls you’ll be able to have earlier than high quality takes a nostril dive.
- Jitter — Variations between despatched and acquired information packets. If these variations are important, customers would possibly miss total phrases or sentences in the course of the name.
- Latency (or ping) — Measures the delay from one caller to a different. Excessive latency is usually brought on by community congestion and leads to echoing.
- Packet loss — Refers to information packets that by no means attain their remaining vacation spot. If it exceeds 1%, calls will seemingly have uneven audio and different distortions.
Many may even allow you to simulate calls with completely different VoIP codecs. It is a parameter that defines how a lot compression occurs throughout a name. Extra compression makes packets smaller, leading to sooner transmissions and decreased community congestion.
However an excessive amount of compression can decrease audio high quality to the purpose it’s unrecognizable. The secret’s discovering a superb steadiness that works to your crew.
Lastly, among the higher VoIP high quality exams calculate your MOS by factoring in all of those parts and metrics.
It’s additionally value noting that some instruments allow you to run exams for various numbers of simultaneous calls, and you might even have the ability to change the origin location of the decision.
As you alter completely different parameters and variables, you might get a special MOS. For instance, you might need an ideal rating proper subsequent to your router however a decrease rating in the event you’re on the opposite facet of the constructing.

Find out how to run a VoIP high quality check
There are dozens of instruments that allow you to check VoIP high quality.
To maintain it easy, I’ll present you the right way to do it in just some minutes without spending a dime, and what to make use of in the event you’re a developer or want extra granular insights.
Free on-line VoIP high quality exams
Many enterprise telephone suppliers have their very own on-line VoIP high quality exams you should use without spending a dime. They’re very straightforward and fast, making them excellent in the event you’re not fairly positive what’s happening and simply want a easy technique to inform in case your community is secure sufficient.
Most measure latency, jitter, add velocity, and obtain velocity. Some (however not all) additionally measure packet loss and calculate your MOS.
RingCentral’s high quality of service check is among the greatest free choices I’ve seen.
The perfect half about this check is that it offers you MOS. It additionally measures packet loss, latency, and jitter in your audit abstract.
One other standout of RingCentral’s check is the power to regulate your codec. You may as well check as much as 50 simultaneous calls and run the check for as much as 5 minutes — the longer you check, the higher probability you might have of discovering a problem.
As soon as the check is completed, it does a superb job of explaining what all of the numbers imply and whether or not or not your connection passes.
It’s additionally about as straightforward because it will get to run. All you must do is choose your most popular variety of concurrent calls, alter the length, and tweak the codec if you need.
Whereas RingCentral’s is among the most detailed free choices, there are others you should use to validate your outcomes in the event you’d like.
There are different VoIP high quality exams available on the market that you should use, and it is likely to be a good suggestion to attempt a number of to see in the event you get constant outcomes throughout the board. Listed below are some others value trying out:
- Nextiva’s check — Easy possibility for testing as much as 200 simultaneous calls.
- Ooma’s check — Straightforward technique to test latency, jitter, add, and obtain velocity.
- 8×8’s check — Much like Ooma, however enables you to change the host.
General, RingCentral’s is probably the most detailed, however these different free VoIP high quality exams may give you extra information factors to make sure accuracy.

Community monitoring software program (paid with a free trial)
Community monitoring software program is often utilized by IT community directors to make sure their community is operating easily. It’s additionally helpful for figuring out points with varied parts (routers, servers, firewalls, switches, and many others.).
You may as well use them for testing VoIP community high quality, they usually present way more detailed info than any of the free instruments on the market.
SolarWinds VoIP community high quality supervisor is among the greatest. As an alternative of one-off exams from time to time, it runs repeatedly within the background.
Though SolarWinds isn’t free, there’s a 30-day free trial. You possibly can check your community for a full month to see how its efficiency modifications over time. From there, you’ll be able to determine if you wish to maintain utilizing it.
Past fundamental VoIP high quality stats, it additionally supplies WAN efficiency metrics. It additionally supplies contextual info associated to efficiency points.
For instance, you’ll be able to see the precise IP addresses of units which are inflicting jitter, latency, or packet loss. This can enable you decide if name high quality points are associated to {hardware} in your community or one thing else.
The software program does an entire lot greater than that, nevertheless it’s an incredible different in the event you want real-time information or extra information factors to know and enhance your MOS.
