A method, comprising: at an electronic device with a display and one or more input devices (208, 210): establishing a first communication link between a first party and a user in response to a first action by the user; displaying, on the display, a first representation of the first communication link as an item on the display; while the first communication link is ongoing, and while maintaining the display of the first representation, establishing a second communication link between a second party and the user in response to a second action by the user, placing the first communication link on hold, and making the second communication link active; concurrently displaying, on the display, a second representation of the second communication link as an item on the display while maintaining display of the first representation and an affordance for initiating a third communication link, wherein the second representation is displayed at a greater intensity as compared to an intensity of the first representation to indicate that the second communication link is active; while the second communication link is ongoing, and while maintaining display of the first representation, the second representation, and the affordance, detecting, via the one or more input devices, an activation of the affordance; and in response to detecting the activation of the affordance: establishing the third communication link, wherein the third communication link includes the first party, the second party, and the user; and displaying, on the display, a third representation (410, 416) of the third communication link, wherein the third representation (410, 416) comprises combining at least a portion of the first representation and at least a portion of the second representation, wherein the at least a portion of the first representation and the at least a portion of the second representation are displayed at a same intensity. establishing a first communication link between a first party and a user in response to a first action by the user; displaying, on the display, a first representation of the first communication link as an item on the display; while the first communication link is ongoing, and while maintaining the display of the first representation, establishing a second communication link between a second party and the user in response to a second action by the user, placing the first communication link on hold, and making the second communication link active; concurrently displaying, on the display, a second representation of the second communication link as an item on the display while maintaining display of the first representation and an affordance for initiating a third communication link, wherein the second representation is displayed at a greater intensity as compared to an intensity of the first representation to indicate that the second communication link is active; while the second communication link is ongoing, and while maintaining display of the first representation, the second representation, and the affordance, detecting, via the one or more input devices, an activation of the affordance; and in response to detecting the activation of the affordance: establishing the third communication link, wherein the third communication link includes the first party, the second party, and the user; and displaying, on the display, a third representation (410, 416) of the third communication link, wherein the third representation (410, 416) comprises combining at least a portion of the first representation and at least a portion of the second representation, wherein the at least a portion of the first representation and the at least a portion of the second representation are displayed at a same intensity. establishing the third communication link, wherein the third communication link includes the first party, the second party, and the user; and displaying, on the display, a third representation (410, 416) of the third communication link, wherein the third representation (410, 416) comprises combining at least a portion of the first representation and at least a portion of the second representation, wherein the at least a portion of the first representation and the at least a portion of the second representation are displayed at a same intensity.
