`ABSTRACT
`(57)
`Systems for and methods of delivering telephone calls using
`the combination of a data channel and a voice channel are
`disclosed. A data channel connection with the telephone
`handset may provide pre-call information used to set up
`incoming and outgoing calls which are ultimately connected
`using a voice channel. Use of the pre-call information may
`permit the same handset to be associated with multiple
`secondary telephone numbers from which calls appear to
`have been made and to which calls appear to have been
`placed.
