VOIP is extremely popular and has penetrated the home and business market to an exceptional degree. VOIP was led initially by the home consumer, with small businesses piling into the market after being attracted by the cost savings associated with the solution. The VOIP market is fueled by the cost savings that it offers, however it is soon readily apparent that there is a world of telecommunication functionality which is quickly available and adopted by users after the deployment. As the popularity of VOIP increased amongst small to medium sized businesses, the larger, enterprise class companies have also seen the light and moved to adopt it too.
VOIP works over the existing network, utilizing bandwidth to deploy telecommunications as well as regular network traffic. This effectively makes the traditional telephone infrastructure redundant and it is no longer necessary, however a VOIP system is exceptionally simple to manage and produces a cost saving in terms of support as well as actual call costs.
Major objections to adoption include the reduction of call quality which was typical of many early deployments. Such concerns are largely redundant today - the call quality is typically exceptional with current deployments. Nevertheless, there are occasions when there is an issue with call quality, or clipping of speech transmission or rarely, a complete loss of the call audio on one side or both of the call.
Running a trace route test will help you assess if you are suffering from latency problems (latency is the metric for measuring the cycle time for the call data to make the round trip between the two callers over the network) or having a server connection issue. You can also run a Brix Network Test: this will produce a very detailed report and indicate the Mean Opinion Score. The Mean Opinion Score, or MOS, is a metric for reflecting the quality of the speech received at the destination end of the call circuit - it runs from "1", the lowest call quality, through to "5" which is the highest quality.
When you run VOIP tests, it is important that you run them through the same circuit/network which is being used by the callers reporting an issue.
Network connection testing should also be undertaken. You should be looking for congestion problems and traffic bottlenecks. Where there is data congestion, you will typically find that there is speech stuttering over the VOIP call - this is known as delay jitter. If the delay in transmission is too large, audio data cannot be effectively carried by the network and results in a playback issues at the receiving end of the call.
If a router is also handling too many data packets, some of them may be dropped (known as "packet drop"). This will also impact the playback quality of the audio data transmitted over the network. You will need a latency factor which is no higher than 150ms, and indeed significantly lower than this if VOIP is to be usable at all in many situations.
Running these simple diagnostic checks will in most cases restore call quality. However, if the problem is more involved, there are numerous advanced configuration solutions which will help you restore call quality in almost every modern VOIP installation.
