VoIP Call quality is important for both VoIP service Provider as well as for individual users. The outcome of VoIP Technology, VoIP Call is the easiest and cost efficient means of telecommunication. Contrary to the traditional telephone system, VoIP calls use packet switched network. In packet switched network, information travels as packets along the routes and reaches the destination. The benefit of the packet switched network is that in this transmission the resources are allocated without sharing. To know more about VoIP calls check here: End to end working of VoIP Call
VoIP Technology is one of the most popular technologies of the present day. Individuals for personal uses along with corporate users all benefit from VoIP Technology. VoIP is the revolutionised form of the traditional telephone system. Through VoIP Calls, VoIP Technology presents the best solution to high international call charges. But even though the progress of VoIP Technology is remarkable, there are many places where the technology is yet to reach. In addition to these places, there are many other areas where though VoIP connectivity is available, the call quality still remains an issue.
The quality of VoIP Call is important in business because it is through the call quality that one can get more clients or lose them. This is necessary for both Reseller VoIP and Hosted VoIP business. It is essential to maintain the call quality for these retail VoIP businesses. VoIP Providers provide mobile dialers to consumers for making calls. Mostly app-to-app calling is free of cost. But calls to normal GSM and landlines without an internet connection on the receiving end require some credit balance. This balance is easily available from the Service Provider in form of recharges through cash or online payment modes. Also, the call charges are different for each destination. Some providers offer special calling packages for certain destinations. But it differs from one provider to the other.
Some of the factors that affect the VoIP Call quality are as follows:
One of the basic requirements for VoIP Call is an internet connection. High-speed internet connection produces the best quality call. But as in many areas, internet connection is not stable the call quality suffers. Lack of bandwidth causes packet loss.
The amount of bandwidth consumption also affects call quality. If bandwidth consumption is more, in poor network condition the call quality drops. There are many VoIP calling apps or mobile dialers which consume less bandwidth and hence performs better.
The Mobile Dialer used to make the VoIP Call is also a factor that affects the call quality. The quality of the mobile dialer can degrade the call quality. So it is better to keep dialers of the latest version to avoid any type of issues. Also for a Service Provider, it is better to keep multiple dialers.

As a VoIP Service Provider, one must be aware of the number of concurrent calls necessary. The cc call limit when exceeds puts the load in the network traffic and as a result call quality suffers.
The type of codec used is an important factor that affects the VoIP Cal quality. This is because of the higher the compression, lessens the size of data for transmission to the other side. But the downside of the high compression is that voice quality also suffers.
Network latency takes place due to the distance that a packet travels and also the changing network conditions. The delay increases with the increase in distance and the number of router-hop a packet takes to reach the destination.
Jitter occurs when due to network delays the packets arrive at different time intervals and not in the same order as they were sent.
With several of the aforementioned issues affecting the call quality, it is for the service provider to provide proper VoIP Services to maintain a stable quality. On the consumer’s end, a good and stable internet connection is necessary. Meanwhile, the service provider sees all the technical details for managing call quality.
Some easy and useful tips for achieving this are as follows:
As a Service Provider, one should offer good quality mobile dialer to its customers. A good quality dialer solves many technical issues which would otherwise create a problem. Also, a regular update of the application is necessary for security purposes.
When network load increases, it affects the call quality. And therefore as a service provider, one should ensure that the network is large enough to take on the load. For Reseller VoIP and Hosted VoIP, it is better to choose the number of concurrent calls according to the number of consumers or clients.
Many service providers offer a free demo for their services. So it is better to check the quality of the service through the demo. It also ensures good quality service for the consumers. Free demo helps one to check the quality of the service and select it thereafter. Through this demo, one is able to check the details of software, mobile dialer, call quality and all other related points.
To solve the issue of latency, one has to prioritize the VoIP Traffic over the network. Some common techniques for prioritising VoIP Traffic are policy-based network management, type of VoIP Server, the bandwidth reserved, class of service and MPLS.
Similarly, jitter buffers help to solve the issue of jitter. The jitter buffer temporarily stores arriving packets for minimising delay variations. They discard packages which arrive too late.
The usefulness of tunnelling software is huge for VoIP Calls, Mobile Dialers with tunnelling protocol can bypass firewalls and VoIP blockages. Tunnelling Protocol further reduces bandwidth consumption during the calls resulting in better call quality.
