Efficient and effective communications are initiated from the selection, at a first user device, of a link in a resource. Based on this selection, a communications request is transmitted to a server. In addition, identification information of a second user device (such as a telephone number or an Internet Protocol (IP) address) is transmitted to the server. As a result of this request and identification information, a communication response is received at the second user device. This communications response may be of various types, such as a voice call, a message, or a rich call.
