Experiencing VoIP issues? Troubleshoot with the simplest steps.

In the digital age, businesses are increasingly adopting internet calling services over traditional or standard telephone systems. Quality VoIP services help businesses manage operations more efficiently by offering new business-centric features such as IVR and unlimited extensions. VoIP allows significant benefits for users and including cost savings, mobility, hone and service portability, and the integration with other applications

However, with benefits, there are certain challenges as well, that the technology encounters such as interoperability issues and architecture complexity. While these issues calls for expert solutions, there are certain smaller issues that can be trouble shooted easily. A critical prerequisite for a seamless VoIP service is a steady internet. Slow internet can degrade VoIP services to a great extent. Hence, it is very handy if one knows some basic troubleshooting. This helps to get the system back on track at the earliest with zero downtime.

For Choppy Voice

Voice clarity can be affected by different factors not limited to side tone, and the background noise Additionally, a common cause for a choppy or uneven voice during VoIP calls is inefficient bandwidth utilization. Blaming the internet service provider is the first thing that most of us do; however, the service provider is not always the reason for this. VoIP system converts analogue phone signals into digital forms and sends them over internet networks as packets. Each upload or download of these packets takes up to 90 kbps of the bandwidth. Hence, the first best VoIP Test for choppy voices is a ‘bandwidth usage check.’ This will identify the application on your network that is eating away your bandwidth, which you can easily delete or shut to get clear voice.

In case the bandwidth usage check returns normal, you can also check for any possible system malware and spyware. Sometimes the phone may also be defective. Replace it with another one and see how it works.

If the problem still persists, you might consider resetting your router and prioritize voice applications. If you are lucky enough, you will find that the VoIP Issues have been resolved. However, at times the router issues could be more critical and require an expert.

For Echo

Echo is a result of electrical impedance mismatches in the transmission path. Well, this problem can be resolved with some small tricks and it is easy to fix them in VoIP services.  All you need to do is while speaking on the phone, cover the mouthpiece with your hand or handkerchief. Notice if there is any reduction in the echo’s strength. If yes, then turn your phone’s volume down. If the problem still persists, try these VoIP test solutions with immediate effect.

  • Place the router at some distance from your system (Monitor, CPU etc.).
  • Use a corded phone only.
  • Remove caller id or any other devices connected to your router or phone.
  • Crosscheck your wiring and ensure that they are neither damaged nor too long.
  • Replace old devices with new standard ones.

For Jitter Issues

Jitter is key to frictionless VoIP Services. The jitter buffer first collects the incoming packets from the sender and then directs them to the receiver. It does all this at an even pace so that the packets never overlap or drop. But at times the buffer may be wrongly configured. This impacts  VoIP Quality. The ideal buffer length is between 30 to 50 millisecond. Anything lower than 30 ms will result in voice drops, and anything higher than 50 ms will increase voice delays.  Ensure the following points when reconfiguring the buffer.

The buffer must not be too small or too big. Buffer transmission depth can be anything between 30 to 50 millisecond. Ensure that the network admin identifies the root problem correctly, whether it is hardware or software based.

For Outdated Router

Last but not least, an outdated router can also impact VoIP service quality. An outdated router may lack the functions and features that the VoIP connection needs. This makes it paramount to ensure that the router is capable of efficiently handling the network traffic. If not, replace it with a new one that suits your required user count and bandwidth size. A dual-band router is highly recommendable if you are replacing the old router. Dual Band routers help to avoid network congestion very efficiently within a dedicated channel.


Performing VoIP troubleshooting can no doubt save you important business hours, but at times the problem can be too critical.  In times like this, call your internet service provider as well as the VoIP service provider without delay. Solving VoIP Issues do not take much time usually. But handling on a priority basis will definitely save valuable business hours.
