5 Tips on how to improve your VoIP calls

A core characteristic to measure VoIP success is voice. All other benefits of VoIP will not mean much if the quality of the call has dropped after digitizing your phone system or moving the office home.

We know that the quality of a call depends highly on how the VoIP vendor has engineered their system. However, quality also depends on the underlying network, thus, it depends on a combination between IT staff and Internet providers as well.  

First step, even before making any changes to your hardware and network is to contact your VoIP provider. They might be able to help you identify the issue. Also, contact your Internet Service Provide to rule out any problems they might be experiencing which are out of your reach. 

If this investigation results on everything working right, here goes potential common issues that could be happening to your system making quality decrease:  


1. Jitter: We have already talked about this issue in one of our previous articles. It happens when the packages of data are not delivered in the right order and it might be caused by a network congestion, improper queuing or configuration errors. How can you solve it? 

First you can try upgrading your Ethernet cable to a Category 6 (CAT 6). You could be using an outdated one. If the problem persists, you can try configuring a buffer. This will make sure data is delivered in the right order. 

2. Buy a new headset: Recording artist use the best headphone on the market, right? Why is that? Basically, because the headset you use actually makes a difference. Therefore, it might be time to upgrade yours.

Which one do I choose? You don’t need the most expensive set on the market. However, noise-cancelling, delivering sound in both ears and corded USB are features that contribute to a more stable sound quality. 

3. Make sure your router knows VoIP: Home networks are usually simpler than business-class meaning that advanced features such as VoIP traffic are dealt with in a better way. Wireless mesh systems provide an excellent solution for home use. 

When choosing the right router you have to make sure it has the following  characteristics. First, Quality of Service (QoS) is a feature that lets you prioritize specific traffic. And second, Session Initiation Protocol (SIP) that ensures data is delivered to the client and the server reliably. And third, Virtual LAN (VLAN) can help group data where the latency is the lowest. 

4. Reduce your bandwidth: Home networks are generally centered around a single router. You can reduce the amount of bandwidth used by other apps. However, this might not be feasible in a family house with kids doing school work, etc. An alternative would be to set up a dedicated VLAN only to run VoIP traffic. 

5. Interference clearance: Check on which frequency your phone runs (5.8-GHz phone or 2.4-GHz phone). Decide which traffic will run in each spectrum. 


Do not despair if the problem persists. As an ultimate resource you can always hire an expert. VoIP consultants also offer optimization network services.
