BRIEF DESCRIPTION
FIG. 1 is a block diagram of an embodiment of a call block system; and
FIG. 2 is a block diagram of an illustrative embodiment of a general computer system.



DETAILED DESCRIPTION
Disclosed herein are embodiments of methods and systems that enhance features provided by a call blocking system. A call block feature can be disabled or bypassed, under particular conditions, to provide a way for trusted people to remain in communication in case of an emergency.
A computer implemented method includes outputting a dial tone from a call block system. The dial tone indicates to a calling party that a call block feature is enabled for a party. The computer implemented method includes storing messages for the party when the call block feature is enabled.
A computer-readable storage medium includes operational instructions that, when executed by a processor, cause the processor to initiate a call from a calling party to a called party. The computer-readable medium further includes operational instructions that, when executed by the processor, cause the processor to receive, from a call blocking system, a dial tone indicating that the called party has a call blocking feature enabled. The computer-readable medium further includes operational instructions that, when executed by the processor, cause the processor to cause a message for the called party to be stored at the call blocking system.
A voice telephony device includes a processor and a computer readable storage medium. The computer readable storage medium includes operational instructions that, when executed by the processor, cause the processor to instruct a call block system to enable a call block feature for the device for a particular period of time. The call block feature prevents the device from receiving incoming calls during the particular period of time. The call block system stores messages from incoming calls addressed to the device when the call block feature is enabled.
FIG. 1 is a block diagram of an embodiment of a call block system 8. The system 8 comprises a call block component 10 that provides a call block feature for any of a plurality of parties of a telephone system. The call block component 10 may provide a do-not-disturb feature, a snooze feature, or another call block feature that enables each party to control whether or not incoming calls to its phone are to be blocked. The call block feature may be a timed call block feature that blocks incoming calls for a particular time period and/or until a particular end time, and thereafter does not block incoming calls. Each party may configure its own particular time period and/or end time. The timed call block feature may be enabled, for example, for a mobile telephone of a person who is to attend a meeting, for a telephone of a person who is to take a nap, or for a telephone of a family who wishes not to be disturbed during a meal. Optionally, user interaction with the call block feature is enabled through a privacy manager feature of the telephone system.
Each party may configure an amount of time that the call block feature is enabled for its phone. When the call block feature is enabled for a party 12, an incoming phone call for the party 12 does not cause the party's phone 14 to ring. Although the party's phone 14 is not ringing, the call block component 10 may provide a ringing signal to a calling party 16 and/or may play a message to inform the calling party 16 that the party 12 does not want to be disturbed. Optionally, the call block component 10 may provide, for each party, an associated inbox 20 to receive messages for the party when the call block feature is enabled for the party. The messages can be left by calling parties whose calls are blocked. Each party can play back recorded messages in its associated inbox 20.
The call block component 10 is responsive to a call block disabler 24. The call block disabler 24 acts to disable the call block feature for a party based on one or more conditions. By disabling an otherwise enabled call block feature for the party 12, one or more subsequent incoming phone calls for the party 12 are not blocked, and thus can cause the party's phone 14 to ring. Examples of the one or more conditions for disabling the call block feature are as follows.
The call block disabler 24 can count one or more respective numbers of incoming calls for each party whose call block feature is enabled. The call block disabler 24 can disable the call block feature for a party in response to a number of incoming calls for the party being greater than or equal to a threshold. This feature allows the call block feature to be automatically disabled for a party if an unusually large number of calls intended for the party have been blocked. This feature addresses situations where repeated attempts are made to contact the party within a short period of time, for example. The threshold(s) for a party can be configured by the party using his/her phone.
The number of incoming calls may be a total number of incoming calls 30 for the party from a plurality of calling parties while the call block feature is enabled for the party. Alternatively, the number of incoming calls may be a number of incoming calls 32 from one calling party while the call block feature is enabled for the party.
Running counts of the total number of incoming calls 30 and the number of incoming calls 32 are stored in a memory 38. The counts are initialized (e.g. to zero) for a party when the party enables the call block feature.
The system 8 may store a multiple-calling-party threshold 34 and/or a single-calling-party threshold 36 in the memory 38. The call block disabler 24 can use the multiple-calling-party threshold 34 for disabling the call block feature based on the total number of incoming calls 30 from a plurality of calling parties. The call block disabler 24 can use the single-calling-party threshold 36 for disabling the call block feature based on the number of incoming calls 32 from one calling party. The multiple-calling-party threshold 34 may differ from (e.g., be greater than) the single-calling-party threshold 36. Each party may configure its own multiple-calling-party threshold and its own single-calling-party threshold.
The call block disabler 24 can cause an incoming call to bypass the call block feature if a calling party enters a particular personal identification number (PIN) 40 or an alternative pass code associated with the called party. Each party can configure its own PIN or alternative pass code with the call block disabler 24 for storage in the memory 38. Each party can share its PIN or alternative pass codes with a limited number of trusted parties. The PIN 40 or alternative pass code may cause only the incoming call to bypass the call block feature, or may cause the call block feature to be disabled for subsequent incoming calls to the party. Use of the PIN 40 or alternative pass code enables the call block feature to be remotely disabled.
The call block disabler 24 can cause any incoming call from a toll operator 42 or a public safety party 44 (e.g., police, fire, E911) to bypass the call block feature. One or more toll operator phone numbers 46 and/or one or more public safety phone numbers 48 can be stored in the memory 38 for access by the call block disabler 24.
The call block component 10 may output different dial tones to a party dependent on whether its call block feature is enabled or disabled. For example, the call block component 10 can output a first particular dial tone 50 to a party whose call block feature is disabled, and a second particular dial tone 52 to a party whose call block feature is enabled. The first particular dial tone 50 may comprise a standard dial tone presented to parties of the telephone system. The second particular dial tone 52 differs from and is audibly distinguishable from the first particular dial tone 50. The second particular dial tone 52 is dedicated to indicate that the call block feature is enabled for the party. When the party 12 puts its phone 14 in an off-hook state while its call block feature is enabled, the phone 14 presents the second particular dial tone 52 to the party 12. The second particular dial tone 52 serves to remind the party 12 that the call block feature is enabled for the phone. The second particular dial tone 52 may be outputted regardless of whether the associated inbox 20 for the party 12 is empty or otherwise not full, or is full. The second particular dial tone 52 (and optionally the first particular dial tone 50) is outputted by a dial tone generator 54.
