Web Answer Agent
Spend 1 minute to install the click to call widget plugin to your website, and do a very little configuration, then you can start answering calls. When an incoming call arrival, you will see which page is customer calling from.
Fall to Your Physical Phone
You will never need to worry about to have a person logged in to the web agent. Because if there is no web agent logged in, or the web agent missed the calls, calls will be forwarded to your physical telephone.
