An increasing number of businesses are beginning to recognise the benefits of voice over internet protocol (VoIP) and the positive effect it can have on the way in which corporate communications are carried out.
However, enjoying a VoIP system is never a simple case of installing the hardware and moving on. There are always ways in which businesses can improve their communications systems, which can sometimes suffer from some basic but largely surmountable problems.
Get rid of the jitters
One of the most common problems associated with VoIP systems, jitter is an issue that can have a substantially negative impact on voice quality. However, it is also a problem that is usually quite straightforward to solve.
Information, or voice data, is divided into packets, each with the ability to travel by a different path from the sender to the receiver.
When they arrive at their intended destination in a different order than when they were originally sent, it can lead to poor or scrambled audio.
The good news is that jitter, which often refers to the measure of the variability over time of the latency across a network, is quite simple to solve.
The use of a jitter buffer makes it possible to store arriving packets in order to minimise delay variations. Packets that arrive too late are discarded.
No room for delays
There are several types of delay that occur on most VoIP networks, which can affect quality and lead to an echo effect during calls, which hardly presents an image of professionalism to colleagues and potential clients.
The best way in order to prevent delays is to prioritise the VoIP traffic over your network. This can be achieved by policy-based network management, bandwidth reservation, Type of Service, Class of Service, and Multi-Protocol Label Switching (MPLS). Ensuring you have a router that is up to the job is also an important consideration.
Bad hardware equals bad service
Perhaps one of the most common causes of issues to do with call quality. Many smaller businesses use their internet connection for both voice and data, which is only advisable if you happen to have a router that has the ability to prioritise VoIP traffic.
By not having a router geared towards to packet prioritisation, it leaves the call quality across your network at risk of suffering degradation.
Getting the right router is not expensive, but can prove the difference between a good network and a bad one.
