    摘要： A method and system are disclosed for providing call screening in conjunction with a variety of network-based call services. An exemplary method for providing a called party at a called party station with call screening includes: (a) forwarding a call to the called party station (CPS) to a voice mailbox so that a caller can leave a message for the called party; (b) initiating a simplex call to the CPS; and (c) bridging the call forwarded to the voice mailbox and the simplex call to the CPS so that the called party can hear the caller leaving a message for the CPS; (d) initiating a duplex call to the CPS in response to signaling received from the CPS; and (e) bridging the call forwarded to the voice mailbox and the duplex call so that the caller and the called party are in communication with one another. In one embodiment of the present invention, the step of initiating a simplex call includes the step of delivering a distinctive ring to the CPS indicating that the caller is leaving a message for the CPS. In another embodiment of the present invention, the step of initiating a simplex call includes the step of transmitting a call waiting indicator to the CPS. In yet another embodiment of the invention, the step of initiating a simplex call includes the step of transmitting a signal to the CPS indicating that the calling party station will pay for cellular charges associated with the call.

    摘要： A telephony call-waiting system for clients having a computer with a video display unit (PCNDU) and a public-switched telephony network (PSTN) telephone connected to the PSTN by a single line, keeps a status indication of the client's Internet connection status and, during periods of time the PC/VDU is connected to the Internet, alerts the client by an alert signal over the Internet connection of any waiting PSTN calls. In a preferred embodiment the client's PC/VDU is adapted to provide an audio and/or visual alert event when an alert signal is received, and to provide for a user-initiated response to an alert, accepting or rejecting a call. In the event a call is accepted, provision is made for connecting the accepted call to the client's PC/VDU as an IP call. In some embodiments several calls may be dealt with at the PC/VDU, and features are provided such as caller-ID on the client's VDU. Several ways of accomplishing the call-waiting system are taught.

    摘要： A method and related apparatus are provided for detecting the presence of a call waiting signal on a telephone line, where the call waiting signal is embedded in various signals. The call waiting signal frequency is isolated from the various other frequencies. The isolated call waiting frequency is then biased so that only the positive voltage portions of the signal are allowed to pass. Each positive voltage pulse as well as the zero voltage pulses are then sampled to determine whether they are representative of a biased call waiting signal. Each time a determination is made, one is added to a count on an up-down counter. When the count reaches a predetermined number, a call waiting signal is detected on the telephone line. Preferably an alarm signals the presence of a detected call waiting signal to the user. A disconnect switch interrupts a modem so that a person using the modem on the same telephone line will have sufficient time to answer a detected incoming call.

    摘要： A method and system for making an emergency call while on-line on a computer includes an input device attached to the computer adapted to receive a command from a computer user for making an emergency call. When user initiates a command to make an emergency call from the input device, a software program executing on the computer overrides all computer functions and transmits the emergency call to an emergency call receiver through the network or by a telephone line. The software program takes priority over all other computer applications on the computer. The invention transmits the emergency call using a computer generated signal, or by computer generated voice, or by way of a facsimile transmission. The emergency call may also include additional pre-stored information held in a memory program, such as address, telephone, e-mail, and medical information, which may be automatically sent along with the emergency call to the emergency call receiver.
