    摘要: A method and system for reducing background noise during a telephone call. When a caller begins dialing a telephone number, the system receives an ambient noise level measured near the caller's telephone. The system then computes an inverse noise waveform, which corresponds to the received ambient noise level. The inverse noise waveform is then transmitted along the same telephone line used by the completed call. The inverse noise waveform reduces the ambient background noise from the caller's location for the duration of the telephone call.

    摘要: An easy to use (easy-reach) dialing system that connects a calling party with a called party based on data received over a first communication channel and a second communication channel. A calling party calls an easy-reach device and sends data to the easy-reach device over a second communication channel. The easy-reach device calls the called party based on data received over the second communication channel and connects the calling party with the called party.

    摘要: The present invention provides a centralized messaging service method and apparatus in which a message is sent to each of a subscriber's messaging services. When a sending party wishes to leave a message for a receiving party, the sending party activates his/her user device and enters the access number for the centralized message service. The centralized message service receives the communication signals from the sending party which include a receiving party identifier and the message to be sent. The centralized message service then retrieves profile information from a database corresponding to the messaging services of the receiving party based on the receiving party identifier entered by the sending party. The centralized message service then forwards the message to a portion of the receiving party's messaging services based on the profile information retrieved from the database. The centralized message service then monitors the messaging services to determine if the receiving party has retrieved the message from any of the messaging services. If the receiving party retrieves the message from any of the messaging services, a delete command is sent to at least a portion of the other messaging services based on the profile information retrieved.

    摘要: A system and method for allowing a parent to control the use of an ancillary credit or debit transaction card which is issued to a child. A central computer communicates with an issuer computer having a data base containing account information and spending limits for the transaction card and the parent can set a spending limit for the ancillary card given to the child. When the child presents the ancillary transaction card to a merchant in payment of merchandise, the merchant swipes the card and contacts a central computer for card authorization. If the credit limit of the ancillary card holder has been exceeded according to the data base, a method of contacting the parent is transmitted to the central computer. The central computer initiates contact with the parent via two-way communications, for example, two way pager, cellular telephone, or other personal communication service, and queries the parent whether to authorize the transaction by increasing the spending limit of the ancillary cardholder or refusal of the transaction. The parent responds to the central computer via the two-way communications device, and the central computer forwards an approval/refusal code to the merchant. In this manner, a parent can control the maximum transaction card spending by a child.

    摘要: A system and method for processing telephone calls to a personal telephone number, such calls being of the type in which a call to a called party's personal telephone number results in a page to a pager of a called party and the caller's call is held in the network to be bridged to a return telephone call of the called party, employs type-ahead for faster perceived system response while not permitting free paging. In particular, although type-ahead is permitted, the page is not immediately initiated upon receipt of the last character of a valid command string prior to the end of the announcement that is played to the caller upon his call reaching a bridging and signaling unit. Instead, the bridging and signaling unit is arranged to respond so that it appears to have accepted and executed the command, and moves into the next phase of operation, e.g., music on hold. However, the page is not initiated until it is determined that both 1) the entire time for the announcement has elapsed from the receipt of the caller's call, i.e., the time of commencement of billing has arrived, and 2) the caller remains on the call at that time.

    摘要: A conference call sound level balancing method and system for selectively muting a conferee whose sound environment is loud enough to dominate other conferees of a conference call. The method is operable on a system that includes a network-based conference bridge and a sound equalization platform that is coupled to each telephone of a conference call. If one telephone connected to the conference call has a higher noise level than the other branches of the call, thus making it so the other branches cannot obtain speaking privileges, a predetermined touchtone key is entered at the noisy telephone. The sound equalization platform responds by automatically measuring the ambient sound levels of the respective branches of the conference call and balancing the speaking privileges for the respective call branches of the conference call.
