VoIP telephony is demanding in requirements, this is a reality.
The main reason behind VoIP issues are jitter, latency, and packet loss. If these are not under control, the consequence is poor call quality.
Since this a must for our clients, we have spent a lot of time researching and identifying the main requirements to ensure VoIP performance.
Use a cable
When making calls, you can not rely on the Wi-Fi. If you want to avoid having issues, use a cable to connect your computer to the internet.
Unless your routers are configured to have 100% coverage in your office, you are bound to have drop off in certain areas.
Is not only about internet speed, but also about having quality equipment. Even with the fastest connection, if you are using poorly-configured or cheap equipment, VoIP call quality will be affected.
The IT team should test, evaluate, and upgrade (if necessary) the hardware through which the call will pass and ensure they do not become a bottleneck.
Your network has a lots of traffic going through, but not all of it is treated equally.
VoIP is more sensitive to internet quality, therefore it needs to be prioritised above all other types of internet traffic.
The IT team has the ability to set up this prioritisation, known as “Quality of Service”. This is done only once, and it will protect your call quality when someone in the office or at home decides to start a great download.
Configure it right
VoIP technology works different and it needs to be properly set up.
For example Zoom web conferencing or Google Hangouts might calibrate your video to low quality, whereas a VoIP upstream provider might just cut off your call entirely.
Nobody ever suspects about headsets and they can cause all sorts of issues. Funny enough, buying expensive ones with a great amount of features, does not guarantee voice quality, rather on the contrary.
Here you are a few examples of the problems headsets can cause:
- A headset bluetooth would disconnect every time a microwave was switched on
- The microphone is sometimes disabled when an unusual loud audio signal is detected (such as when placing the headset down on the desk)
- An auto-shut-off feature (power-saving mode) can be triggered when a call takes too long or there is a pause in the conversation.
