435 Mbps) 2. Using G.729 codec: Bandwidth per call: 31.2 kbps Number of calls: 5 Total bandwidth required: 31.2 kbps×5= 156 kbps (0.156 Mbps) Step 4: Add additional bandwidth for network overhead It's a oman mobile phone numbers database good idea to add about 20% more bandwidth to account for network overhead and ensure quality. For G.711 example: Total overhead: 435 kbps×1.2= 522 kbps (0.522 Mbps) Other considerations Be sure to check your network plan to make sure you have enough bandwidth to meet your VoIP needs, especially if other devices or applications are also using the network.
Even on low bandwidth! Get started How much bandwidth does VoIP require? VoIP requires at least 80-100 kbps (or less) of bandwidth for a single call. However, multiple users require more bandwidth. The more users there are, the more bandwidth is required. VoIP bandwidth requirements also depend on the codec. Codecs compress and decompress voice data during calls. G.711 codec: Requires approximately 80 Kbps per call (64 Kbps voice + 16 Kbps overhead). This is high quality, but uses more bandwidth. G.729 codec: Uses approximately 32 kbps per call.
