Size voice trunks by codec and estimate call quality from loss and jitter.
Per-call packet size × 50 pps × concurrent calls; MOS from R-factor with loss/jitter penalties.
Total bandwidth: 0.87 Mbps (872.0 Kbps)
Per call: 87.2 Kbps · Packet size: 218 bytes
Estimated MOS: 4.35 — Excellent
Toll-quality voice; imperceptible impairment.
Effective R-factor: 90.3
VoIP Bandwidth & MOS Estimator helps you size voice trunks by codec and estimate call quality from loss and jitter. It is commonly used by network admins, IT support teams, ops engineers for voip bandwidth calculator, mos estimator, g711 bandwidth.
Uses 50 pps (20 ms) framing with RTP/UDP/IP/Ethernet headers and R-factor to MOS mapping.
