Information may be provided to a telephony customer from an overlay service by causing a second stream of audio information to be overlayed on a primary stream of audio information. The overlayed information may be whispered to the user by causing the overlayed information to be compressed into a limited frequency spectrum which is inserted into a manufactured gap in the primary audio stream. This allows the user to continue to hear the main audio stream while also hearing the overlayed information. The overlay service may provide administrative information, advertisements, music, and/or Internet search results via the overlayed audio. Users may issue commands to the overlay service, to have particular information transmitted via overlayed audio. Where the user is also associated with a telephony application running on a computer platform, the overlayed information may be incorporated onto the information being shown to the user on a computer display.
