摘要： An improved speakerphone that may be viewed as a modification of a conventional half-duplex speakerphone that includes transmit and receive attenuators for alternatively isolating either a speaker or a microphone from a phone line. The attenuators are controlled by a controller that compares a signal generated by the microphone with a signal received on the phone line to determine which of the transmit or receive attenuators should be turned on. In the present invention, a first variable gain amplifier is connected so as to amplify the signal generated by the microphone prior to the signal being connected to the controller, and a second variable gain amplifier is connected so as to amplify the signal received on the phone line prior to the signal being connected to the controller. The first and second variable gain amplifiers have adjustable gain controls that are connected such that the gain of the first variable amplifier is decreased when the gain of the second variable amplifier is increased and vice versa. The adjustable gain control of one of the adjustable gain amplifiers is accessible to the user of the speakerphone and allows the user to adjust the threshold at which his voice will take over the conversation.

摘要： A messaging system allows a message recipient to assign different message lengths to different messages. In one embodiment, the recipient sets the length of time per message. In another embodiment, the recipient programs the messaging system with codes that, when matched, enable longer messages. The recipient assigns the codes to “preferred” senders. The senders transmit the code, either explicitly, for example by a sequence of keystrokes, or automatically, for example by transmitting caller identification.

摘要： An apparatus and method are disclosed for connecting a headset microphone alternately to a telephone line and an alternative device. The apparatus includes a device connector for connecting the apparatus to the alternative device, a telephone connector for connecting the apparatus to the telephone line, and a microphone connector for connecting the apparatus to the microphone. The apparatus also includes a switching circuit connected to the device, telephone, and headset connectors. The switching circuit can be used with or included in a CTI module. The switching circuit connects the telephone connector to the headset connector in response to sensing a voltage greater than a predetermined threshold on the telephone line. When the voltage sensed returns to a value less than the predetermined threshold value, the switching circuit reconnects the headset connector to the device connector.

摘要： A telephone with a mute ringer function having an automatic disabling feature includes multiple call indicators including a ringer. A power output reducing device is connected to the ringer to reduce the ringer volume prior to a connection between the telephone and a remotely located telephone. A volume switch control unit is connected to the power output reducing device to reset the ringer volume to a level established prior to a volume reduction upon detecting either connectivity to the remotely located telephone or the termination of the connection. A selecting device selects an incoming call indicator prior to the connection to the remote telephone. A reverting device automatically reverts power to a previously selected incoming call indicator upon either establishing connectivity for the call or the termination of the call. In a preferred embodiment, the ringer power output reducing device and the ringer power output resetting device include a volume switch connected to the ringer.

摘要： A method, system, and device for performing diagnostic testing of digital feature phones remotely located from a diagnostic device includes establishing a bi-directional communications link between a digital feature phone and the diagnostic device. The diagnostic device transmits signals to the digital feature phone which activate a troubleshooting program in the feature phone to perform a self-test and access an error list stored in the memory of the feature phone. The diagnostic device can direct the feature phone's troubleshooting program to execute different troubleshooting procedures; depending on what information is needed. The feature phone transmits the results of the troubleshooting procedures back to the diagnostic device, whereupon the diagnostic device determines the performance characteristics of the feature phone based upon the troubleshooting results. Based on the performance characteristics, the diagnostic device determines whether more information is required regarding the feature phone's operational status. If more information is required, the diagnostic device can request a second round of troubleshooting. In one embodiment, the diagnostic device and the feature phone are connected via an ISDN network which provides at least two B-channels for data communication and a D-channel for transmitting signaling data. The diagnostic device transmits the request for troubleshooting to the feature phone via a D-channel and the feature phone returns the troubleshooting results via the D-channel as well. The D-channel communication between the diagnostic device and feature phone occurs in the form of message associated UUI (MA-UUI) signals. In this manner, the entire troubleshooting procedure can be executed on a customer's feature phone without interrupting service to the feature phone.

摘要： A server allows a worldwide telephone number associated with a local telephone to be shared by one or more remote telephones. A call placed to the worldwide telephone number rings at the local telephone and at least one of the remote telephones. The server stores a set of telephone numbers to be associated with a worldwide telephone number serviced by the switch to which the local telephone is connected. The server receives notification of a telephone call from a calling telephone to the worldwide telephone number The server retrieves the set of telephone numbers associated with that worldwide telephone number, and places calls to telephone numbers in the set through the switch. The server then causes a connection to be made between the local telephone or the remote telephone, depending on which telephone goes off hook first, to the calling telephone. In one embodiment of the present invention, the server causes the connection to be made by causing the switch to make a conference call connection between the calling telephone and the remote telephone.

摘要： A telephone utilizes a grid of light beams to generate signals that are unique to particular key regions of the telephone in response to interruptions of light beams that intersect at the particular key regions. The key regions of the telephone are arranged in a matrix of rows and columns and the light grid includes horizontally and vertically oriented pairs of light sources and photo detectors that have respective light beam paths passing through rows and columns of key regions. The intersection points of one of the horizontal and vertical light beam paths correspond to particular key regions. In one embodiment, the light sources and photo detectors are raised from a surface of the support structure such that the light beam paths cross the matrix of key regions at the exterior of the support structure. In another embodiment, the telephone generates DTMF signals in response to interruptions of the intersecting light beams, and the telephone has holes formed completely through the support structure at the key regions where the light beam paths intersect.

摘要： An apparatus and method for using local wiring (102) with a wireless phone (114) are described. The local wiring is coupled to a local phone network (110). Where the local wiring is not engaged with a current call, transmission of calls from the local phone network to the local wiring is inhibited (112, 218) in response to receipt of a wireless transmission by the wireless phone. A ring signal is transmitted (216) to another device (104, 106) coupled to the local wiring. The wireless transmission is converted (214) for transmission over the local wiring. In response to the other device responding to the ring signal, the converted wireless transmission is transmitted (216) to the other device over the local wiring.
