Telecom has undergone many changes in the last few decades. In the 80s, you were using landline phones to connect with someone, and in the mid 90s mobile phones were introduced. They made communication quite easy. Unlike landline phones, cell phones are based on digital technology.
They use radio waves to send sound signals from one end to another. Apart from voice calling, they offer several other features like text messaging, multimedia calls, etc. Mobile phones are great for personal use, but this telecommunication technology is quite expensive when it comes to commercial purposes. Because of this, organizations started deploying voice-over-internet protocol telephone systems.
VoIP allows you to make multiple calls over the Internet at no additional cost. Moreover, these telephony services have simplified the video conferencing and meetings of the businesses. Many vendors offerbusiness VoIP services in Chicago and around the world at very affordable prices. You can contact a nearby service provider to enjoy the Internet telephony services at any time.
VoIP has countless benefits. But those who do not put effort into managing VoIP quality often face call drop problems. Here we will discuss why call quality drops in VoIP telephone systems and how to avoid it. Before going on, let us throw light on the working principle of VoIP.
How Voice Over Internet Telephony Works?
The VoIP system takes analog voice signals as input and converts it into small data packets. These data packets are sent over the broadband line to the dedicated destination. At the receiver end, the digital data packets are again converted into sound signals.
What Is VoIP Jitter?
For clear voice quality, the data packet must reach the receiver end without any damage. If some packets are lost or go bad on the way, it can interrupt the voice signal, and the call may drop. Similarly, if the ethernet packet does not arrive in an orderly manner, it causes jitter (call delay). As a result, both parties cannot talk comfortably.
Jitter is measured in milliseconds and can degrade the quality of the call if increased beyond 50 ms. If the bandwidth of your broadband connection is not enough there is a high chance of getting jitter. According to expert VoIP business serviceproviders, in addition to poor internet speeds, jitter may occur for the following reasons.
Although wireless networks increase mobility and allow you to use the network at any location in the office, it reduces the quality of VoIP calls. The reason for this is that wifi networks are shared by multiple users (around 50), which eventually divide the bandwidth of the network.
The other major cause of call drops and jitter is network congestion. When too many devices try to hook up with a single network node, it becomes overwhelmed with traffic. And this results in dropped or poor quality calls.
Poor Quality Hardware
If your router, modem, or ethernet cable is damaged, there may be a call quality issue. Moreover, there are two types of VoIP calling: software-based & hardware-based. If you have chosen hardware-based VoIP services, installing A-grade cordless or traditional phones with analog telephone adapters is essential. Any technical issues in ATA can stop VoIP entirely.
From core to access layer, VoIP configuration must be done very carefully. Apart from this, the network must also be designed effectively to transmit data packets smoothly and to maintain QoS. The configuration error can halt the network and deteriorate the voice quality.
How To Measure Jitter?
If you are often facing call drops, words jumbled, and voice delay with your internet telephone, it is vital to measure the jitter. There are two types of jitter: internal and external. Internal jitter is related to the organization’s internal network and can be measured easily by executing ping jitter tests. However, you need to seek the help of business VoIP service Chicago providers to gauge the external jitter.
How To Reduce Jitter?
You can reduce the jitter of VoIP calls by increasing the bandwidth of the network, installing quality hardware, utilizing jitter buffers, and checking the QoS as well as other configurations.
