DO I NEED TO WORRY ABOUT BANDWIDTH,
HOW MUCH DOES A CALL USE?
The short answer is no! 3cx calls use less than 100kbps each with top notch quality to easily beat any mobile, so even a standard 20Mbps ADSL2 connection could support up to 200 calls. In most cases your existing business Internet connection will support your phones without impacting your day to day use.
