Tips for Improving VoIP Call Quality

More and more companies are choosing to make the switch to VoIP which offers unrivaled call quality and communications reliability. That being said, there will be times when you’ll have less than perfect call quality. In such instances, there are things you can do to ensure that you have uninterrupted calls from your end to the other party. In this post, we’ll take a look at some of the causes of poor VoIP call quality as well as simple fixes you can apply that cost close to nothing in terms of finances, resources and time.

Choppy or Bad Audio Quality

VoIP is dependent on your broadband internet connection to transmit data packets. If you start to get phone calls that don’t sound clear or have whole swathes of conversations cut off, it’s time to look into strengthening your broadband connection. The first thing you can do is to monitor each workstation’s internet speed over a couple of days to determine which computer uses up a lot of bandwidth as well as the times and days which experience the largest load with regard to broadband demand.

Once you’ve done so, you can come up with recommendations to free up bandwidth, all of which will not interfere with the smooth functioning of office operations. For example, you could ask the staff to pause downloads during the day and then resume them later in the evening.

Alternatively, you could buy an assured contention ratio from your Internet Service Provider which essentially ensures that voice services get priority on the network. For example, a contention ratio of 100:1 means up to a hundred users might be sharing the line at any time. Whereas a 1:1 ratio means only a single connection is allowed on the line. This guarantees a constant speed at all times and would be suitable for a business willing to pay the cost.

You may notice this contention problem at home. For example at six o clock on a Sunday evening, your internet connection might seem slow. This may be because lots of people on your road are trying to connect to the internet at the same time. They all have to share the same physical cable which the data must travel on. Another time, when there are fewer people online, for example, 7 am on a Monday morning, the connection can seem fast and responsive.

Lastly, you could cut down on the number of internet-dependent processes running such as backup services, relegating them to perhaps the weekend.


An echo is basically sound bouncing off two terminals infinitely, making communication between two individuals next to impossible. This is a simple problem. It can be solved by asking the other party to turn the volume down on their set.

Latency or Lag

This basically denotes a pause between the time one sends voice data and the time the other party receives it. Ideally, there should be no lag at all. Voice quality should stay constant. Owing to the superior voice quality you can expect from VoIP.  Your latency value should be 200ms or lower if you’re looking to preserve voice integrity. If you find it to be higher, call up your Internet Service Provider and ask them to apply fixes on your connection.

Poor Audio and Computer Equipment

Sometimes, no matter how fast your broadband connection is, you’re bound to have questionable call quality. In such instances, look into replacing older computer models as well as issuing your staff with better-quality headsets, especially if they work from home from time to time.  If you experience any static or frequency buzzes while using your VoIP phones, consider moving your phones away from each other in the office, and look into getting cordless phones if these problems don’t let up.
