How to use this calculator
- Enter concurrent voice agents and per-agent media bitrate.
- Add average CRM, desktop, and screen traffic per agent.
- Include simultaneous supervisor video users.
- Add network overhead and operational reserve, then calculate.

Contact Center Bandwidth Requirement Calculator
Estimate a contact center's busy-hour network requirement by combining concurrent voice sessions with agent desktop traffic and supervisor video use. The calculator adds protocol overhead and an operational reserve, then reports the provisioned bandwidth for one network direction. It helps separate steady agent workload from a safety buffer before sizing a primary or failover circuit.
Calculator
Planning inputsFormula
Base kbps = [(agents × voice kbps) + (agents × desktop kbps) + (video users × video kbps)] × (1 + overhead). Required = base ÷ (1 − reserve).
What the result means
The result is provisioned bandwidth in each direction under the entered simultaneous workload. Use separate uplink and downlink measurements if traffic is asymmetric.
Software updates, recordings, quality-management uploads, backups, and remote-agent VPN concentration can create additional demand not represented by average desktop traffic.
Example calculation
For 150 agents at 90 kbps voice and 250 kbps desktop traffic, plus 8 video users at 1,500 kbps, 10% overhead, and 25% reserve, provisioned demand is 92.4 Mbps each way.
Tips for better results
- Use busy-hour logged-in and active-agent counts.
- Measure CRM traffic during screen loads and case saves.
- Model recording uploads and updates separately.
- Keep failover circuit capacity aligned with minimum operations.
- Apply QoS without assuming it creates capacity.
Frequently asked questions
Should I enter staffed agents or active voice agents?
Use simultaneous agents expected to carry voice during the busy interval. Staffed but idle users may still contribute desktop traffic, which can be modeled separately if material.
Is voice bandwidth counted in both directions?
The result is stated for each direction because live calls transmit and receive media. Check the smaller available uplink or downlink.
How should I estimate desktop traffic per agent?
Use network monitoring during representative busy periods and exclude traffic already modeled in the voice or video fields.
Are call recordings included?
Not automatically. Local recording streams, cloud uploads, playback, and quality-management workflows should be added to desktop traffic or modeled separately.
Does the reserve replace a growth forecast?
No. Reserve handles short-term variation and operational safety; sustained staffing growth should be modeled with a higher agent count.
