The integration of the Internet with the existing PSTN found much interest recently. While in many cases the aim is to use the Internet as a carrier medium for voice phone calls, we will present a proposal to extend classic Internet multimedia services to users on the PSTN. We introduce an architecture and prototype implementation that allow users on the PSTN to actively participate in MBone audio conferences. We present a set of building blocks for applications using voice access via telephones and give an overview of how these can be combined to meet individual requirements. Finally, we discuss application scenarios, usage experiences and potential future enhancements to improve usability and to extend the range of available services.
