ABSTRACT:
Information, such as advertising, is presented to VoIP users (12) via a combination of telephone and data streams during session initiation via an IP phone or a personal computer (18). A proxy server (20) that receives the call request coordinates with a media server (30) to transmit targeted advertising to the caller during the post dial delay interval. After the advertisement concludes, the call continues normally.
