Optimizing the sound on VOIP technology used in the PABX device, so that the previously unclear voice becomes clear.
The steps I took are as follows:
- Quality of Service (QoS): Implement QoS on your network to prioritize VoIP traffic over other types of traffic. This helps reduce latency, jitter, and packet loss which can affect sound quality.
- Codec Selection: The codec is what compresses and decompresses voice data. Some codecs require more bandwidth but offer better quality. G.711 is a high bandwidth-high quality codec, while G.729 uses less bandwidth with a slight reduction in quality.
- Echo Cancellation: Echo can be a significant issue in VoIP systems. Ensure that your PABX system has a good echo cancellation feature.
