Abstract

A network services complex having an audio conference bridge, a data conference bridge, a tone receiver and a data store announcement system is disclosed. The complex is connected to a telephone network via a host toll switching center. Customers dialing over the network using a keyset can selectively establish audio-only, data-only and combined audio/data conferences. Announcements from the data store prompt the customer in the use of the arrangement and request the user to reenter information when the customer makes an error. Should the customer make too many errors, an operator is summoned.
