In short
A call centre network needs certified cabling at every seat with spare points, voice and data on separate networks with quality of service, managed PoE switches on UPS, dual internet connections, high-density WiFi for other devices and monitoring to spot problems before agents do.
Design keys
| Aspect | Recommendation |
|---|---|
| Seats | At least one outlet per seat, plus spare for layout changes. |
| Voice | Separate voice network and end-to-end quality of service. |
| Switches | Managed, with PoE for IP phones, connected to a UPS. |
| Internet | Dual connections from different carriers with automatic failover. |
| WiFi | High density for laptops, phones and training rooms. |
| Monitoring | Alerts on outages, saturation and link errors. |
Common mistakes
- Cabling only today’s seats and running out of points for the next campaign.
- Mixing voice and data without prioritisation: voice breaks up when someone downloads a file.
- A single internet line for the whole floor.
- Racks without UPS or proper ventilation.
