Once you decide to ditch your traditional landline for good and upgrade to a business Voice over Internet Protocol (VoIP) phone system, you need to prepare for the transition. One of the big things you need to know is whether or not your current internet service can support your new system. Because VoIP relies on your existing internet connection to make and receive calls, it’s important that you have sufficient bandwidth to allow for reliable and crystal-clear calls.
But what exactly is bandwidth, and how will you know if your bandwidth is sufficient enough to handle your VoIP phone system?
Bandwidth refers to the amount of data your connection can transmit in a given time. Think of it as a freeway. With a wider freeway (higher bandwidth), more vehicles (data) can travel. For businesses, higher bandwidth is usually preferable since you can do more at the same time.
Do you have enough bandwidth for VoIP?
The amount of bandwidth you need depends on the number of concurrent VoIP calls you expect to make. Businesses that usually make and receive a number of phone calls each day (such as call centers) as well as those businesses that engage in bandwidth-intensive activities (such as collaborating on graphics, streaming content, etc.) need to secure an internet service with a higher bandwidth. However, companies that only partake in light internet activities can do with less.
To give you an idea on how many calls your bandwidth can support, please refer to the table below:
Number of Concurrent Calls Minimum Required Bandwidth
1 100 Kbps Up and Down
3 300 Kbps Up and Down
5 500 Kbps Up and Down
10 1 MBps Up and Down
One of the best ways to determine whether your internet connection is efficient and if your bandwidth is adequate is through running a Speed Test.
