Ideal Speed for VoIP

Choose the appropriate Internet speed for your VoIP service.

VoIP (Voice over Internet protocol) connections require a minimum amount of line efficiency in order to provide a tolerable service. The two main factors that affect speed of VoIP transmission are latency and throughput.

Latency

This is the speed of transmission. It is defined as the time taken, for a packet to travel over the network from your computer to its destination and back again. This is measured in milliseconds (ms). For a VoIP connection, you will need a round-trip time of less than 150ms.

Throughput

This is the amount of data that can be sent over time and is measured in bits per second (bps) . The Throughput required for VoIP ranges between 30 and 90 kbps (kilobits per second) depending on quality expected.

Assessing Ideal

The end user must decide what speed is ideal. A higher level of service is more expensive. An individual might not be willing to pay for a high-quality line, while a business reliant on its telephone network might consider better quality a necessary expense.
