How to Deal With Poor VoIP Quality
It is usual to experience poor call quality for people who are using a VoIP system. Most of the user does not have any solution to deal with the issue, so in this article, you will be discussed 5 causes of it, along with it you will also discussed about solution to the problem.
5 Most Probable Causes for Poor VoIP Call and Its Solution
Jitter is considered to be a basic problem that is related to the connectionless network as well as packet switched network. This is due the information known as voice packet is divided on to packets; each packet has the ability to travel in a different way from sender to receiver.
When this packet arrives at their destination in different sequence than they were actually sent, then it results in poor audio.
The technical measure of variability over the time of latency is known as jitter. It is considered to be the most common call quality issues.
Solution: Make Use Of Jitter Buffers
Jitter buffers help in storing the packets temporarily that help to delay variations. The packets are generally discarded if they arrive late.
Latency is described as the time taken by it for speech for exiting the mouth of the speaker and reaching the listener’s ear.
Basically, there are three types of delay found in today’s VoIP network;
- Propagation delay
- Handling delay
- Queuing delay
It generally sounds like an echo.
In a vacuum, light travels at 186000 miles each second whereas and electrons known to travel through the copper approximately at a speed of 125000 miles each second.
Fiber network that is known to stretch halfway around globe that is 13000 miles each second tends to induce one-way delay approximately 70 milliseconds. However, the delay created is totally imperceptible to ear of a human. Propagation delay along with handling delay can cause speech degradation.
Handling delay is caused by devices that tend to forward frame through network. It can impact the network of traditional phones, but they seem to have a bigger issue in the packetized environment.
Queuing delay: Queuing delay happens when the packets held in a queue; this is basically due to congestion, generally on outbond surface.
Prioritize VoIP traffic known to yield latency and improve jitters over the network. Given below are some of the widely used techniques for prioritizing VoIP traffic.
- Policy-based network management
- Type of service
- Multiprotocol label switching
- Bandwidth reservation
- Class of service
Problem: Poor Internet
Generally, most of the ISPs are basically designed for surfing the web and they are not designed for advantages of VoIP. Transporting voice packets is totally different and it requires an additional set of IP, which might not be provided by your ISP.
Solution: Business Class High Speed
In order get over this issue, you can seek for high-speed internet service of business class, almost all cable service providers offer this to their clients. You can grab the deal to avoid further issue.
Problem: Router is inadequate
If your router is disturbing then make sure to change it. If it has gone old then it might be the main reason for the problem.
Solution: Installing A Specialized VoIP Router
This can be considered to be one of the most common causes for call quality related problems. It is seen, that most of the small business makes use of their internet connection for both data and voice. This can be done as long as your router supports to prioritize VoIP traffic.
By default it is configured for packet prioritization without a router, however, another user can also impact call quality on your network.
Say for example, while you are on a call, another user on your network is downloading a legal file, if you do not have packet prioritization, the call quality could be degraded.
Using VoIP router thus prevent this issue from happening, this is because in your network a VOIP router gives priority to voice traffic.
Problem: Internal Network Not Properly Configured
VoIP technique is recent in the market and it is less than 10 years old. Most of the company does not demand high-quality contents for VOIP communications. Generally, cal quality issues occur when the company chooses to route both voices as well as data over the same network which not properly configured.
Solution: Network Configuration
Network configuration is the easiestt way to handle this problem. Opting for router that are business VoIP capable is configured properly will solve the problem.
The poor quality VoIP calls can be diagnosed easily. It is necessary for your VoIP service provider to identify and work with you in order to correct these issues. It is recommended to find a different provider if they fail correct call quality issues.
