ABSTRACT:
A system for a proxy service to provide telephone conferencing services and personal telephony services. Users can participate in the conference by connecting through different types of networks using a device having one or more types of communication lines connected to the proxy service. A primary user can request the proxy to call each one of the users and establish the conference. The primary user may accomplish this through a data line using data requests or though a voice line using voice requests. Typically, the primary user provides a telephone number for each user. The primary user can also provide with specific times of when calls should be placed, identification information for each user, the type of conference, and other conference parameters.
