`
`A caller ID based call routing feature is dcscrib~o.--d lor blocked
`and non-block~-d caller I D's. A processing system in the pub·
`lie switched telephone network (PSTN) receives first identi(cid:173)
`l)'ing information for identify the source of a telephone call
`and associates additional information stort.-d in a memory
`with the first identifying information. The additional infor(cid:173)
`mation may be information about the calling party initially
`downloaded to the memory by a subscriber. Once retrieved
`from the memory by the processing system, the additional
`information may then be trnnsmitted to the subscriber via the
`Internet for display on a monitor or to the subscriber's tele(cid:173)
`phone for display on a telephone display. Another leature
`described is a brnnch calling feature where the subscriber
`may program a processing system within the PSTN to lor·
`ward an incoming call to two or more end units (e.g., tele·
`phones) simultaneously.lfthe call at an end unit is answered.
`answer supervision signaling is trnnsmitb.:d back to the pro(cid:173)
`c~'Ssing system which th~'ll terminatt.'S all other c<tlls. The
`processing system then connects the calling pany to the sub(cid:173)
`scriber. "Ibe branch calling may be made lor <UlY combination
`of local. long distance, and cellular telephone numbers.

`FIELD OF THE INVENTION
`
`'Ibis invention relates to telephonl.! sl.!rvices and. in particu(cid:173)

`the subscriber's telephone service and to various novel fca·

`BACKGROUND
`

`(dialing options). The 2nd party (called party) also has
`options available such as call lorwarding. but tlii.'Se 1\:atures
`typically ~-quire access from the f1tst or second party's device
`and are extremely awkward to program. The user interaction
`is not only awkward, it is limited and requires intcr.1ction with
`the telt.'Phone company to provision them. In other words,
`past systems lor provisioning, meaning addition, modifica(cid:173)
`tion, or control of telephone features, required a subscriber to
`make the ft.!uture selection through the telephone business
`10 office. Central office workers would then implement the pro(cid:173)
`visioning under request of the business office.
`Call Forwarding is one popular provision. Thl.!re is signi·
`ficationtransmission degradation for Call Forwarding to take
`place. TI111 calling piU'Iy pays for a call to the edge d~o--vice, and
`15 the edge subscriber. the called party, pays for the c;tll to the
`forwarding number. Fur enhanced inbound call control to
`occur, a dir~-ct 3rd-party call control means is ~~~~-ded.
`A variety of services have arisen tn uddrcss the problems
`mentiom.-d above. Many nf these systems ullow the called
`party to make changes to his/her call Ji.1rwarding anributcs
`which do not allow direct 3rd-party call control. 'lb~-se ser(cid:173)
`vices provide good user interaction, some via the internet. but
`they rely upon the toll network through the use of "800"
`numbers. lbis requires the subscriber to pay by the minute
`H and does not allow thesubscribertotakeadv-dntageofnumber
`portability in order to obtain 3rd-party call control. There are
`other toll network mechanisms for remote call li1rwarding.
`For exumple, MCI oilers a service where the customer can
`remotely change the lbrwarding target number lor "800"
`numbers. Contacting the ultimate end-user belore tl.!rminat·
`ing the first incoming c-dll is similar to the manner in which
`''800" credit calls and collect calls are processed, but these arc
`not done ut the local subscriber lt!vel.
`In addition to these toll services, there arc edge devices that
`perform some of the same services. Edge devices such as
`phones and PBXs that include voice mail, inter-active voice
`response, call forwarding. speed calling, etc., haw been used
`to provide additional cull control. Th1.>se devices allow the
`phone user direct control over incoming and outgoing calls.
`The disadvantage of edge devices is that they add cost.

`user to puy lor two lines. provide lower 4uality of service, and
`cannot provide the same h ..... ·el of functionality as a system that
`controls tbe l>sTN dirl.!ctly. 'lbl.!re arc Voice Over Internet
`Protocol (\lbiP) products emerging. that providl.! better user
`interlaces and control but they do 1wt take udvuntagl.! and

`
`SUMMARY
`
`A system for allowing a subscriber to remotely control
`features is described herein along with various telephone
`leatures that may be programmed into the system. A sub(cid:173)
`scriber may be any custom~-r using the telephone Sl.!rvice, in
`contrast to employees of the PSTN who may usc special
`communication networks within the J>STN. Two lo'UCh fea(cid:173)
`tures are caller ID (CID) ba~>d call routing and brdnch call·
`ing. The system allows the subscriber to set up a feature where
`the CID sig~wl is detect1.-d within the !•STN and automatic<~lly
`associated with stored information relating to the caller. The
`stored information may have been previously enten.>d into a
`memory within the PSTN by the subscriber via the world
`6S wide web. '!be CID signal may be also used to route the call
`to one of more forwarding numbers or to take any other
`action, such as blocking the call. This feature also allows the
`
`30
`
`3S
`
`P~-ople have used various means lor limiting interruptions
`due to the telephone. In the past, ~'Ople u~>d switchboards
`and secretaries to screen incoming, or inbound, calls. Voice
`mail systems took over some of this mle both in the home and
`in the Cllntral office. 'lbday, there arc web-based companies
`managing 3rd-party call control, via the toll-switch network,
`which allow users to enter call control information through a
`web portal. 1berc arc also edge devices in each of the public
`telephone company's central offices which provide local con(cid:173)
`trol, but olli:r an extremely limited number of features lUld do
`not provide true 3rd-party call control.
`The web-based toll systems provide good user interaction
`but they are not economical and cannot take advantage of
`local number portability because they do not provide local
`control and connectivity.
`The Public Switched Telephone Network (PSTN) consists 40
`of a plurdlity of edge switches conn~'Cted to telephones on one
`side and to a network of tandem switches on the other. The
`tandem switch network allows conni.'Ctivity betWI.'Cn all ofthe
`edge switches, and a signalling system is used by the PSTN to
`allow calling and to tr.msmit both calling and called party 4~
`identity.
`Until now, optional features were provided by the local
`service tdl.!phone com puny (tel co) through the edgl.! switch at
`the centml otlice (CO). It was not possible to provide optional
`features through any other means. Control of these features ~o
`was done through the first party (calling party) or the second
`party (called party), or worse yet, manually by culling the
`business office.
`In the past, numerous d~.o--vices have been built that allow the
`connection of two lin~-s together at an edge switch. These 55
`devices can be used to add features to a telephone network by
`receiving a call on one line and then dialing out on another
`line. TI1e problem with th~-se devices is that, bL'Cuuse they arc
`connectt.-d through an ~-dge switch, lrdllsmission losses and
`impairments occur, dL-grading thl.! overall conn1.-ction.ln addi- 60
`lion, sigru1lling limitations prevent lull control, by the sub(cid:173)
`scriber or the system, over the call.
`A prcl\:rred embodiment ofthl.! inventive systf.!m described
`herein connects at the tandem, thereby elintinating these
`problems.
`In the edge devices ~-siding in the PSTN central ollices, the
`I st party (the calling party) has numerous features available
