Codecs used: Codec programs compress

It is more efficient and uses less bandwidth. Factors affecting VoIP bandwidth The number of simultaneous calls, codec type, network congestion, jitter, and packet loss are some of the factors that affect VoIP bandwidth. 1. Number of calls: The more calls happening simultaneously, the more bandwidth you need. Each call requires a specific amount of data, so if multiple calls occur, the data accumulates. For example, if each call uses 100 kbps, five simultaneous calls require 500 kbps of bandwidth. Insufficient bandwidth may result in poor call quality, delays, or dropped calls. 2.


And decompress the voice data of VoIP calls. Different codecs use different amounts of bandwidth. For example: The G.711 codec provides high call quality but uses more bandwidth (80 Kbps (64 Kbps voice + 16 Kbps overhead)). The G.729 codec oman mobile phone numbers database uses less bandwidth (about 8-32 kbps per call), which is better for saving bandwidth, but call quality may not be as high. 3. Jitter and packet loss Jitter or packet loss occurs when some voice packets fail to reach their destination, causing gaps or silence during VoIP calls.



When VoIP calls experience jitter or packet loss, delays, distortion, or audio loss can occur. 4. Network congestion Congestion occurs when too much data is transmitted over the network at the same time, causing slowdowns and reduced quality. Any delay caused by congestion can disrupt the flow of voice data, causing audio distortion or delay, making it difficult for users to communicate clearly. 5. Other network use: If other activities (such as video streaming, heavy downloads, or online gaming) occur at the same time as a VoIP call, they will compete for the same bandwidth.
