There are several factors that can cause audio issues and affect the quality of the voice transmission. The network connection, bandwidth and latency all play a significant role in a good VoIP connection.
For the best conversations using a Softphone a headset and microphone should be used, which limits audio feedback. Some others include:
- Pops during loud points in voice. This can be a symptom of over-modulation. Ask the other party to decrease the volume on his microphone.
- A large amount of background noise. This can be corrected in most cases by adjusting the volume, using any Audio Wizard that your particular provider may offer.
- Echo. This symptom is usually reduced or eliminated by the use of a headset and adjusting the volume.
- Poor or scratchy sound. This is usually caused by latency on the network connection or packet loss, but could also be due to a bad network.
- Choppy audio, almost like a staccato sound. Insufficient bandwidth can result in this effect and will be even more pronounced on three-way conference calls or while files on the same network are being uploaded. Increasing your ISP’s level of service (bandwidth) and/or changing the codec to one that uses more compression can greatly help this problem.
