To an IT administrator, causes of some of the VoIP performance issues may seem to be very complex and opaque. After installation, problems can surface very fast resulting in lots of user reports or much worse, calls not coming through. It is very important, for the sake of the success of your business to maintain a good call quality. As such, troubleshooting the VoIP and keeping it at its peak performance is a skill that all IT teams have to master. In this article, we will have a look at how you can best troubleshoot some common VoIP issues and employ different metrics to assess the environment you are operating in – VoIP troubleshooting tips.
This occurs when the network packets arrive too late, too early or they are just out of the normal sequence. VoIP systems are set to accept packets arriving in a consistent and predictable manner and in a certain order. When the jitter occurs, the calls may turn to be very pitchy, difficult to hear or halt altogether. You should compare your bandwidth usage with the jitter rate to find a correlation. If it is not the problem, then you might be forced to dig a little deeper to find the source of the disturbance.
It is common to find calls degrading to a noticeable rate in the burst periods that are sustained. This occurs when large amounts of packets are dropped at once. This may occur when the jitter buffer, meant to correct the network jitter gets to its threshold and is overwhelmed. Poor connection (wireless) or a malfunction on the circuit may also be the cause. Whichever the reason, you will have to track as well as analyze the burst periods to be able to uncover the root cause of the problem.
Call management issues
If the end users report issues of starting calls, there could be several reasons causing things and that you may have to investigate. First, the VoIP server that you have up and running may not be able to handle all the requests that it is receiving, or the IP of the user’s phone is misconfigured or there may be a connectivity problem on either the server or client side.to troubleshoot this issue effectively, you will have to isolate a call, and analyze the point at which it failed or degraded. This will help you get to the root of the problem.
In the long term, having a clear and strong understanding of the network environment and the issues affecting it will place you at a better chance of addressing the issues fast or even before they affect the end user.
