# What internet speed do I need for VoIP to work properly?

VoIP doesn’t need a massive amount of bandwidth, but it does require a stable and reliable connection. As a general rule:

- For a single VoIP line, you’ll need at least 100 Kbps upload and download speed per active call.
- For 10 users making simultaneous calls, you’ll need around 1 Mbps upload and download.

However, for best performance, Edmondson’s recommends business-grade broadband or leased lines with prioritised voice traffic. This prevents call drops, lag, or poor sound quality, even during heavy internet use.

Our team can perform a quick speed and stability test to confirm if your connection is VoIP-ready before installation.
