A properly functioning VoIP system should facilitate your calls seamlessly over the internet, along with the increased functionality that comes along with your business communications solution. The quality of the audio during your VoIP calls depends on the cohesiveness of several variables- one wrong hardware or software choice could result in connection difficulties.

To help you maximize VoIP call quality we put together 5 key suggestions to help your calls stay crystal clear:

1. Minimize Bandwidth Use

The more of your broadband's bandwidth that you can make available, the better the quality of your VoIP systems audio. It's truly that simple. This is possible by restricting downloads during VoIP calls, limiting simultaneous calls, and reducing the quantity of startup programs running on your computers. Also, be sure to schedule your user's system updates and downloads to run outside of business hours- when employees are home and the internet connection is not being used.

2. Upgrade the VoIP Router

In most cases, small businesses will use the same router for data and voice calls. And most times this is FINE, as long as your router is powerful enough to deal with the amount of traffic it handles. You have to make sure your router is able to prioritize VoIP traffic when necessary. If your router doesn't have enough processing power, your call quality can be affected by the other users on the network. To ensure that your calls will not be affected by the other users on your network, switching to a VoIP router is your best option. A VoIP router will make sure your calls are always a priority over data communications. 

3. How to Reduce Jitter in VoIP

When we speak into a VoIP system, our voices are broken up into data packets and then sent to the receiving end. These data packets take several different paths before reaching their destination. When these packets arrive they often are in the wrong order. This is what leads to poor audio quality. The term jitter refers to the measurement of this audio scramble and is the most common cause of poor audio quality during a VoIP call. Jitter buffers can help fix this issue. Jitter buffers store voice packets temporarily to ensure that when they arrive at their destination, they are in the correct order- ultimately clearing up your audio quality and making your VoIP calls more successful.

4. Reduce WLAN Frequency

If your business is like the majority and relies on a wireless connection for VoIP, there is a chance that you can increase the quality of your calls by reducing the WLAN frequency used. The higher the frequency, the more capable your router is of delivering faster data transfer speeds- but, the range and reliability are not as good as that of the lower frequency option. Try switching from the higher to lower frequency option to see how much of a difference it can make for you. 

5. Invest in a Quality Handset

Like most things in this world, the higher the quality, the greater the performance. It is important to check out the headset you're using. If you're using a cheap handset with thin, poorly insulated cables, the quality of your audio is going to suffer. It is important to choose a VoIP handset with a well-insulated, short cord. Additionally, make sure to replace the cord soon after you notice signs of wear and tear.
