Voice over Internet protocol (VOIP) is a technology which enables voice transmission over an Internet connection. VOIP is also synonymous with Internet telephony as it is a communication structure built on internet. One of the key considerations that users bear in mind is that you cannot control the call quality of the receiver’s phone. Here are a few important tips to improve the quality of VOIP:
-
Network: First of all, the network on which data transmission takes place should be configured properly for VoIP traffic, especially if both audio and video traffic move to and fro along the same network.
-
Router: The router that you are using should be of good quality. If you are routing both audio and video traffic over an Internet connection, you need to install a router which prioritizes VOIP traffic. Without a VOIP priority router, the call quality in terms of audio will suffer heavily.
-
Inadequate Internet connection: If your internet connection is not proper, it can also create a major impact on the call quality which is configured over VOIP. Voice packets require special type of internet protocols for smooth transfer which might not be supported by the bandwidth that is allotted to you by your ISP. Cable and DSL high speed connections generally provide these services.
-
Robotic sound voices: If you experience silent or robotic sound voices, then it generally happens because of loss of Internet packets. For efficient and proper transfer and reallocation of packets at another end and to sustain better call quality through VOIP, one requires a minimum bandwidth of at least 100kbps on both sides. Hence, again your Internet connection and your Internet Service Provider play a vital role here.
-
Handsets & Speakers: If you hear echoes during the call, then one reason can be that the headset which you are using is of low quality or someone else has turned his handset speaker on due to which voice gets echo and the receiver hear it after a fraction of second time. The solution to this problem is to tell the other users on call to switch off their handset’s speakers.
-
Poor voice quality: The major reason of poor voice quality can be the presence of JITTER. Generally, all the voice packets travel through a route before reaching to their destination. Now, all these voice packets adopt different routes in order to reach their destination. What actually happens is that due to jitter delay, voice packets reach in mismanaged order due to which voice quality deteriorates. A regulated channel stores the voice packets and rearranges them in the order in which they were send. Hence, it improves the voice quality of VOIP during a call.
-
Latency: If one faces a problem of hearing voice at other end a bit late, then this problem is called Latency in technical terms. In order to avoid latency and to enhance call quality over VOIP, one should use better quality VOIP router which can prioritize VOIP traffic over the network. IT experts can do this in a well-oriented and efficient manner.
