`ABSTRACT
`Systems for and methods of delivering telephone calls using
`the combination of a data channel and a voice channel are
`a
`a
`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 .

`Technical Field
`Applicant has further developed an innovative method of
`The present invention relates to systems and methods for
`providing telephone service , comprising : automatically stor
`setting up and connecting telephone calls , and delivering 30 ing electronic information that indicates an association of a
`information related to such telephone calls using an Internet
`secondary telephone number and a primary telephone num
`ber with a telephone handset in a computer memory asso

`more difficult to manage that volume of calls and messages . 40 number and bridge telephone number pairing with a corre
`The current systems to aid in managing some types of calls
`sponding secondary telephone number and contact tele
`only provide minimal assistance to the user . It is therefore an
`phone number pairing in the computer memory ; receiving ,
`advantage of some , but not necessarily all , embodiments of
`at a switch associated with the server , an outgoing call from
`the present invention to provide systems and methods for
`the handset to the bridge telephone number via a voice
`assisting callers and call recipients with the management of 45 channel ; receiving , at the server , information from the
`switch indicating the outgoing call is being made to the
`calls and messages .
`Additional advantages of various embodiments of the
`bridge telephone number from the primary telephone num
`invention are set forth , in part , in the description that follows
`ber ; receiving , at the switch , information from the server
`and , in part , will be apparent to one of ordinary skill in the
`directing the switch to : ( a ) connect the outgoing call to a
`art from the description and / or from the practice of the 50 contact telephone number associated with the primary tele

`identify the telephone number from which the outgoing call
`is being made as the secondary telephone number .
`SUMMARY
`Applicant has still further developed an innovative
`Responsive to the foregoing challenges , Applicant has 55 method of providing telephone service , comprising : enroll
`ing a telephone handset in a telecommunications system
`developed an innovative method of providing telephone
`service by transmitting call handling information between a
`having a server and a switch , wherein said telephone handset
`handset and a switch using an IP channel or similar protocol
`is associated with a primary telephone number in a database
`channel and by transmitting a voice call associated with the
`associated with the server and switch ; electronically trans
`call handling information between the handset and the 60 mitting an application from the server to the telephone
`switch using a voice channel provided in accordance with a
`handset via a data channel responsive to telephone handset
`voice channel protocol , e.g. , in accordance with CDMA or
`enrollment , wherein said application is : adapted to send
`GSM , 3G , 4G , LTE or like future protocol channels stan-
`instructions to have one or more secondary telephone num
`bers referenced to the primary telephone number in the
`dards .
`Applicant has further developed an innovative method of 65 database , adapted to present visually perceptible call pro
`cessing rules on the telephone handset , and adapted to
`providing telephone service comprising : automatically stor-
`ing electronic information that indicates an association of a
`transmit information indicating a selection of call processing
