Techniques for establishing a connection between a calling party and a called party using the processing of a controller located on a customer premises and served by two incoming telephone loops or ISDN-type channels so as to minimize telephone costs, preserve privacy, and provide heretofore unavailable services. After a first telephony connection is established with the calling party over the secondary loop/channel, the calling party provides control information to the controller. The controller utilizes the control information to establish a connection over the primary loop/channel, and the primary and secondary loops/channels are bridged so that the calling party may monitor the call progression on the primary loop/channel and provide supplemental control information, as needed.
