Not all Internet connections are created equal! Bandwidth and price aren’t the only determining factors in procuring a high-quality Internet connection.
How to choose a great Internet connection for Internet-based voice calling:
- Internet-based voice calls require 60-80 kilobits per second (kbps) of bandwidth per concurrent phone call. We round up to 100 kbps to allow for overhead and for some room to breath.
- ex. For 10 simultaneous calls you will need 1000 Kbps or 1 Mbps of bandwidth.
- Your Internet connection should be capable of delivering a high up-time. Some carriers rate their availability in “nines” of availability.
- ex. “Five Nines of availability” – 99.999% availability
- If your Internet circuit goes off-line, your voice systems will become inaccessible (unless you have a fail-over circuit).
- Bandwidth isn’t the only thing that matters. Bandwidth determines how much data you can fit through the pipe. Latency determines how quickly data is going from one side of the pipe (you) to your cloud providers (in this case Seven Gems).
- The lower the latency the better. Internet-based voice calling sounds best when latency is under 30 milliseconds (ms). Over 60ms and calls will sound robotic, have echo, or may drop.
- A dedicated circuit is highly preferred, almost to the point of it being required.
- Some connections like Cable offer cheap prices, but the bandwidth is shared among local tenants. This will likely cause a degradation in the calling quality.
- Lower cost Internet providers typically have lower quality customer service systems.
- Customer service becomes very important during Internet outages or in order to troubleshoot performance or routing issues.
- Because Internet services like voice have become mission critical, having a solid fail-over connection is important (some say required).
- The fail-over connection should meet the same requirements as the primary connection.
