Method for triggering content download during call setup

A method for causing a calling client station to obtain content from a network server in response to a trigger signal received by the client during the ringback period for a call. The trigger signal is transmitted from a ringback server to a calling client station during the ringback period of call setup, whereby the trigger signal, once received and recognized by the calling client station, causes the station to request and obtain content from a network server. In another aspect, a method for providing content to a calling client station by transmitting a trigger signal to the calling client station during call setup, thereafter receiving at a network-based content server a request from the calling client station, generated in response to the trigger, for a content-download, and providing the content-download in response to the request.
