VoIP (Voice over IP) requires data connection between your premises and our servers. In most cases it would be public internet. However you only need a tiny amount of bandwidth – connection speed in order to use VoIP. Each channel requires 80Kbps (0.08 Mbps), or using compressed codec even smaller – 0.03Mbps. Quality of VoIP will highly depend on the reliability of your internet connection. It does not have to be very fast, but it must be reliable and stable. We also recommend using dedicated internet link for setups with over 5 phones.
