VoIP Bandwidth Calculator

The VoIP Bandwidth Calculator estimates how much network capacity voice calls need after protocol overhead. It is useful for quick planning before blaming call quality on bandwidth.

What It Calculates

• Per-call bandwidth by codec.
• Total bandwidth for concurrent calls.
• Packetization interval effects.
• Planning headroom for practical deployments.

When To Use It

Use it before adding phones, sizing WAN links, checking hosted PBX readiness, or explaining why payload bitrate alone is not the full bandwidth story.

Things To Remember

• VPN, VLAN, and tunnel overhead can increase totals.
• Poor quality can happen even when average bandwidth looks fine.
• Pair with Ping, MTR, and RTP Health for live quality checks.
