ABSTRACT:
An instant message (IM) communication method. An IM communication method can include the steps of: detecting a voice communications identifier in an IM transmitted by a sender; responsive to detecting the voice communications identifier, displaying a selectable icon; and, responsive to a selection of the icon, establishing a voice communications link with the sender. The establishing step can include the step of, responsive to the recipient selecting the voice communications identifier, establishing a Voice over IP (VoIP) based voice communications link with the recipient. Alternatively, the establishing step can include the step of, responsive to the recipient selecting the voice communications identifier, establishing a telephony-based voice communications link with the recipient over a public switched telephone network (PSTN).
