Abstract:
An apparatus for blocking unwanted calls is disclosed. The apparatus incorporates a whitelist which the user can program so that known friendly callers are not interrupted by the apparatus. The apparatus also incorporates a blacklist which automatically rejects known unwanted callers so that the user is not interrupted by these calls. Additionally, the apparatus allows the user to easily add new numbers to either the blacklist or white list and also to delete numbers from the white list, blacklist or master list of caller IDs. For new numbers, callers are presented with a simple but yet effective message that states that the caller should hang up if the caller is a solicitor or telemarketer, or otherwise press zero so that the apparatus can allow the call to go through to the telephone.

       BACKGROUND 
       [0003]    The various embodiments and aspects discussed herein relate to an apparatus for blocking unwanted calls. Telephone marketing over the years has grown into a multibillion-dollar industry. As such, companies will call a large number of homes either through machine automation or with the help of live people. Unfortunately, homeowners do not want to be bothered by these telemarketing calls. Moreover, these calls are typically made when the families do not want to be bothered such as dinnertime. Prior art call blocking apparatuses exists but may be complicated to use and ineffective at blocking unwanted calls. 
         [0004]    Accordingly, there is a need in the art for an improved call blocking apparatus. 
       BRIEF SUMMARY 
       [0005]    The various aspects and embodiments described herein address the needs discussed above, discussed below and those that are known in the art. 
         [0006]    An apparatus for blocking unwanted calls is disclosed. The apparatus may be connected to the telephone in series or in parallel in the home. Regardless, the apparatus intercepts a telephone signal and determines whether the caller ID information contained in the telephone signal is found on a whitelist, blacklist or on neither lists. If the caller ID is on the whitelist, then the call is not interrupted and the telephone signal is allowed to access the telephone so that the user may answer the telephone. If the caller ID is on the blacklist, then the telephone signal is not allowed to access the telephone and the apparatus may hang up on the caller. If the caller ID is on neither the blacklist or the whitelist, then the caller is presented with a message that indicates that should the caller be a telemarketer or solicitor, the caller should hang up or if the caller is not a telemarketer or solicitor that the caller should press zero. If the apparatus detects a zero tone, then the telephone signal is allowed to access the telephone so that the telephone may ring and the user may pick up the call. 
         [0007]    More particularly, an apparatus for blocking unwanted telephone calls is disclosed. The apparatus may comprise a line input, a line output and a processor. The line input may be attached to a telephone jack for receiving a telephone signal which includes a caller id. The line output may be attached to a telephone having a caller id capability. The processor may perform the steps of receiving the telephone signal including the caller id information; comparing the caller id information to a whitelist; and ringing the telephone if the caller id information is matched to a telephone number on the whitelist. 
         [0008]    The steps of the processor may further comprise blocking the telephone signal from the telephone if the caller id information is matched to a telephone number on a blacklist; and presenting a preprogrammed new message to the incoming caller if the caller id is not matched to a telephone number on either of the blacklist or the whitelist. 
         [0009]    The processor further performs the steps of presenting one caller id information to the user from a list of new caller id information; adding the presented caller id information to the whitelist if the user depresses an accept button; and adding the presented caller id information to the blacklist if the user depresses a reject button. 
         [0010]    The processor may further perform the steps of blocking the telephone signal from the telephone if the telephone signal does not include caller id information. 
         [0011]    The preprogrammed new message may indicate that the caller should hang up if the caller is a telemarketer, or press a number on a keypad of the telephone. 
         [0012]    The processor may further perform the steps of deleting one telephone number from a master list of caller IDS, blacklist or whitelist by depressing a delete button. 
         [0013]    In another aspect, a home with a telephone system for blocking unwanted telephone calls is disclosed. The home may comprise a communication link, a first telephone jack, a first telephone cable, an apparatus and a first telephone. The communication link may be in communication with a telephone company for receiving a telephone signal from the telephone company. The first telephone jack may be in communication with the telephone link for providing the telephone signal to an interior of the home. The first telephone cable may be connected to the first telephone jack. The apparatus may block unwanted telephone calls. The apparatus may be in communication with the first telephone cable for receiving the telephone signal. The apparatus may comprise a processor performing the steps of receiving the telephone signal including caller id information; comparing the caller id information to a whitelist; ringing the telephone if the caller id information is matched to a telephone number on the whitelist; a first telephone in communication with the apparatus and controlled by the apparatus. In this setup, the apparatus and the first telephone are connected to each other in series. 
         [0014]    The home may further comprise a second telephone jack in communication with the telephone link for providing the telephone signal to the interior of the home. A second telephone cable may be connected to the second telephone jack. A second telephone may be in communication with the second telephone cable so that the second telephone is connected to a telephone system of the home in parallel to the first telephone.

     DETAILED DESCRIPTION 
       [0021]    Referring now to the drawings, an apparatus  10  for blocking unwanted telephone calls that is easy to use and works is disclosed. The apparatus  10  accepts all incoming calls and compares the incoming caller identification (ID) to a whitelist of caller IDs. If the incoming caller ID is not found on the whitelist of caller IDs, then the call is not allowed to access the telephone  12  and the caller is presented with a pre-recorded message that indicates that he or she should hang up if the caller is a telemarketer or solicitor of any kind or press zero. Friends and family that call the user&#39;s telephone and that are on the whitelist will not hear the pre-recorded message. The call is allowed to access the telephone  12  without the pre-recorded message prompt so that the user (i.e., homeowner) may easily answer the call. Thereafter, the user may add the caller ID of the friend or family to the whitelist of caller IDs by depressing an add to whitelist button. If the caller hangs up, then the user may easily add the caller ID of the telemarketer to the blacklist of caller IDs by depressing an add to blacklist button. Due to the whitelist and blacklist of caller IDs, friends and family are interrupted only once by the pre-recorded message while Robo calls are always blocked and telemarketers are significantly discouraged and effectively do not press zero. 
         [0022]    Referring now to  FIG. 1 , the apparatus  10  has a display  14  and a plurality of buttons  16 - 26 . The buttons  18  - 26  are used to access a master list of caller IDs, the whitelist of caller IDs, the blacklist of caller IDs and to add or delete a caller ID from the whitelist, blacklist and master list. The button  16  is used to select a language for the message. The apparatus  10  additionally has two phone jacks  28 ,  30 . 
         [0023]    Referring now to  FIG. 2 , the phone jack  28  may be in electrical communication with the phone jack  32  that comes into the home  34  from the phone company  36 . The phone jack  30  may be in electrical communication with the telephone  12  in series. In this setup, the apparatus  10  receives all calls coming in through the phone jack  32  and does not allow the telephone signal to ring the telephone  12 . The apparatus  10  either (1) allows the caller ID from the telephone signal to reach the telephone  12  and be displayed on the telephone display or (2) sends only the caller ID read from the telephone signal to the telephone  12  without ringing the telephone  12 . Additional telephones  12  may be connected to other phone jacks  32  located in the home  34 . When a telephone signal comes into the home  34  via the telephone company  36 , the telephone signal is received by the apparatus  10  and the telephone  12  which is directly connected to the phone jack  32  shown in dash lines in  FIG. 2  does not ring. The telephone  12  directly connected to the phone jack  32  at other locations in the house rings only once. The apparatus  10  retrieves the caller ID from the telephone signal which is compared to the whitelist and blacklist in the apparatus  10 . If the caller ID is matched to a number on the whitelist, then the telephone signal is allowed to continue ringing the telephone  12  directly connected to the phone jack  32  at other locations in the house and the telephone  12  directly connected to the apparatus  10 . If the caller ID is matched to a number on the blacklist, then the telephones  12  are not allowed to ring and the call is terminated by the apparatus  10 . The telephone  12  is directly connected to the other jacks  32  throughout the home  34  may ring only once. Thereafter, the apparatus  10  blocks the call. If the caller ID is new, then the apparatus  10  prompts the caller with the pre-recorded message. 
         [0024]    Other configurations are also contemplated. By way of example and not limitation, referring now to  FIG. 3 , the apparatus  10  may be in electrical communication with phone jack  32 . A telephone  12  is not directly connected to the apparatus  10 . Instead, the telephone  12  may be connected to a different phone jack  32  in the home  34 . When the telephone signal comes in from the phone company  36 , the telephone signal is received by both the apparatus  10  and the telephone  12 . As such, the telephone  12  rings once. The apparatus  10  retrieves the caller ID information from the telephone signal which is compared to the whitelist and blacklist in the apparatus  10 . If the caller ID is matched to a number on the whitelist, then the telephone signal is allowed to continue ringing the telephone  12 . If the caller ID is matched to a number on the blacklist, then the telephone is not allowed to ring and the call is terminated by the apparatus  10 . If the caller ID is new, then the apparatus  10  does not allow the telephone  12  to ring and prompts the caller with the pre-recorded message. The apparatus  10  may be placed in series (see  FIG. 2 ) with the telephone  12 . Alternatively, the apparatus  10  may be placed in parallel (see  FIG. 3 ) with the telephone  12 . 
         [0025]    Referring now to  FIG. 4 , a flowchart of the steps that the apparatus  10  takes when receiving a telephone signal is shown. The apparatus  10  receives  100  the telephone signal from the telephone company  36  through the phone jack  32 . The apparatus  10  then determines  102  the caller ID from the telephone signal. If the telephone signal does not contain a caller ID, then the apparatus  10  hangs up  104  on the caller. Alternatively and optionally, the apparatus  10  may answer the call and provide a different pre-recorded message that the call is being hung up  104  since the caller has a blocked caller ID and that should the caller desire to speak to the homeowner, then the caller should unblock their caller ID. After presenting the caller with such message, then the apparatus  10  may hang up  104  on the caller. 
         [0026]    Provided that the telephone signal contains the caller ID information, the apparatus  10  retrieves the caller ID information and compares  106  the caller ID in the telephone signal to the caller IDs on the whitelist and the blacklist If the caller ID is matched  108  to a number on the whitelist, then the apparatus  10  allows the telephone signal to access the telephone  12  so that the telephone  12  will ring  110  and the user can answer the call. If the caller ID is matched  112  to a number on the blacklist, then the apparatus  10  either hangs up  114  or may optionally play  116  the pre-recorded blacklist message discussed above then hang up  118 . If the caller ID is not matched to a number on the whitelist or the blacklist but is a new number  120 , then the apparatus  10  prompts the caller with the pre-recorded new message. The new message states that if the caller is a telemarketer or solicitor that he or she should hang up  114 , or press zero if he or she is not a telemarketer or solicitor. After playing the new message, the apparatus  10  listens  122  for a tone. If the apparatus  10  detects that the zero button or the tone indicated in the message has been depressed, then the apparatus  10  allows  124  the telephone signal to access the telephone  12 . 
         [0027]    Referring now to  FIGS. 1 and 5 , the apparatus  10  reads the caller ID from the telephone signal of all the incoming calls. It places all of the caller IDs on a master list of caller IDs which is shown on the display  14 . The user may scroll up or down the list (i.e., review  126  list of caller IDs) by depressing the up button  24  or the down button  26 . For each of the caller IDs, the display  14  will indicate whether the caller ID is on the whitelist, blacklist or on neither lists (i.e., new). If the caller ID is on the whitelist, then the display  14  will show the word “ACCEPT”. If the caller ID is on the blacklist, then the display  14  will show the word “REJECT”. If the caller ID is neither on the whitelist or the blacklist, then the display  14  will show the word “NEW”. If the caller ID is new, then the user may place the caller ID on the whitelist by depressing  128  the whitelist button  18  or place the caller ID on the blacklist by depressing  130  the blacklist button  20 . The user may also delete the caller ID from the whitelist, blacklist or the master caller ID list by scrolling to the number by depressing the up or down buttons  24 ,  26  and depressing  132  the delete button  22 . 
         [0028]    The apparatus  10  may optionally have three language presets. By way of example and not limitation, the apparatus  10  may present the messages in English, Spanish or German. The language may be selected by depressing the voice button  16  one or more times. For English, the letter A will be shown on the display  14 . For Spanish, the letter B will be shown on the display  14 . For German, the letter C will be shown on the display  14 . Other languages are also contemplated. 
         [0029]    Optionally, the apparatus  10  may also have the capability of allowing the user to record his or her own voice so that the messages provided to the callers are in the homeowner&#39;s own voice. To this end, the apparatus  10  may be supplied with power  38  to operate the microphone  40 . The apparatus  10  may prompt the user to speak into the microphone  40  to record the messages to be provided to the caller during operation of the apparatus  10 . The apparatus  10  may also have memory and a processor to store the prerecorded messages or personalized messages of the user which are provided to the caller during operation of the apparatus  10 . 
         [0030]    The above description is given by way of example, and not limitation. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein, including various ways of arranging the buttons  16 - 26 . Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein. Thus, the scope of the claims is not to be limited by the illustrated embodiments.
