• and wherein the first data communication drives the communication device, in response to the acceptance of the first offer, to transfer the second data communication and to retrieve media from the media service;
• the data system configured to, in response to the resource becoming available, transfer a third data communication for delivery to the communication device, wherein the third data communication drives the communication device to display a second offer that offers to place the second voice call, and wherein the communication device places the second voice call in response to acceptance of the second offer;
• and
• wherein the voice call system is configured to terminate the first voice call in response to receiving the second data communication and to establish the second voice call with the communication device based on the information included in the second data communication and transfer a second voice communication for delivery to the communication device over the second voice call.
