The VoIP, Voice over IP, communication technology has ruling the world from last few years. The real acceptance and popularity that VoIP gained within a short span of time is due to its efficient features and enhanced functionalities.
VoIP technology actually refers to the technique of sending and receiving voice signals over private data networks with the help of Internet protocol and VoIP compatible equipments. Since VoIP systems and services fully deal with voice signals, the quality of voice signals to be transmitted for communication should be very high. That is, the voice quality is the crucial factor that determines the consistency and standard of the communication.
The quality of voice calls reduce due to the disturbances or distortions occurred from echo, choppiness, delay in transmission, etc. Sometimes such problems can be resolved by the network admin who can implement solutions on their own networks.
Some of the major tips that can help you in improving the VoIP call quality are as follows;
- Reducing Echo
A major disruption that that occurs in VoIP communication when users hear the voice repeated that overlaps the current conversation is Echo. Echo usually occurs as a symptom of the acoustic feedback from the phone of the other party. An echo originally generated as follows; your voice will travel across the phone system of the other person, his phone’s speaker outputs the sound, then other person’s phone microphone will picks up on that sound and is transmitted back to your phone as Echo.
It is easy to reduce and prevent Echo. The headset volume of both the users can be lowered to prevent the microphone from catching the conversational snippets from the phone’s earpiece and hence it will reduce the repeated voices. While using soft-phones in communication, it is preferred to use headsets. This will avoid the interference between the computer’s speaker and the computer’s microphone.
It’s another common call quality issue that occurs when the call audio is received as disconnected clumps. It greatly affects the flow of call. It happens when sound packets are lost while transmission and the common suspect behind this problem are mostly the firewall configurations.
- Packet Loss and Delays in Transmission
Some other problems like packet loss, jitter, latency etc. also results in reducing the call quality by missing packets or damaging the equality of sound packets.
Too much traffic in the network may create congestion in the network that may result in loss of packets. Incorrect configurations in routers and other hardware also lead to packet loss. These lost packets generates gap in the conversation and greatly destroys the quality of conversation.
The variation in the latency of packets is called jitter. In order to reduce the effect of jitter, the voice packets can be stored in a jitter buffer up on arrival and before transmission. But, it may result in another problem of transmission delay.
Latency is the time taken for a packet to reach its destination. Latency is not a serious issue that affects the call quality unless it is extreme.
Selection of a good service provider, quality network and internet connectivity are essential to minimize the problems like packet loss, jitter and latency.
- Unified Communication Environment
A complex Unified Communication environment with services from multiple vendors is hard to manage and troubleshoot. Always keep track of the applications and systems of critical VoIP components in your network. So that, any issues can be notified early before they can cause any impact on the business.
- Phone Call Monitoring
Monitor all calls and find when the quality of calls slips behind your standards. Call quality monitoring tools and call sampling facilities are provided by many of the service providers to determine if your call quality isn’t high enough. This helps to get early warnings when there are problems and when the quality falls below the acceptable levels.
- Automate the troubleshooting process
When the call quality drops, immediate troubleshooting is required to find which devices are contributing to poor performance. Analysis of all the devices in the network along a VoIP phone call can help you to quickly identify the reason behind the reduced call quality.
Quality of voice is the primary consideration for a firm to have good business communication with their clients. Decreased call quality can affect the customer experience adversely. Easy fixes to many of the common call quality issues that users might experience is more important for a modern business firm than having a team of dedicated IT staff.
