Abstract: Method for improving the calling procedures of telephones by creating customized messages for telephones coupled to a telephone exchange. The messages are registered on one or more sections of memory located in the telephone exchange and coupled to the telephone. The messages can be played over a boosted loudspeaker or the earphone of the telephone. When the telephone is switched on, but is not in communication with another telephone, the ring loudspeaker, if any, and the earphone loudspeaker are deactivated, and the boosted loudspeaker is activated. When a caller telephone receives a call from a caller telephone the activated boosted loudspeaker plays the chosen registered and optionally other messages. When the caller and the called telephone are hooked up, the boosted loudspeaker is deactivated, the earphone loudspeaker is activated and, thereby, placing the caller telephone in communication with said called telephone in the normal way.

Abstract: A call progress monitor circuit is disclosed for a digital DAA in which digital information is transmitted across an isolation barrier from phone line side circuitry to powered side circuitry. In particular, the call progress monitor circuit of the present invention converts oversampled digital transmit and receive data into analog transmit and receive signals and then combines them to produce a call progress signal that is provided to be fed to a speaker driver circuit. In addition, the call progress signal in one embodiment is filtered with a low pass filter. The call progress monitor circuit in one embodiment includes oversampled digital-to-analog converters, a summing circuit, and a low pass filter. Corresponding methods for monitoring the progress of a call utilizing oversampled digital transmit and receive signals are also disclosed.

Abstract: A telecommunications system and method is disclosed for allowing network operators to download ringing tone pattern(s) associated with one or more musical scores to mobile stations (MSs) according to the music selection of mobile subscribers associated with the MSs. Once executed, the ringing tone pattern provides a musical ringing tone on the MS, instead of the normal ringing tone. In addition, ringing tone patterns can be used to enhance the “distinctive ringing” function within the MS. Thus, instead of using distinctive ringing patterns to represent different called party numbers, different music can be used.

Abstract: An apparatus, system, method, and computer program product for providing a flexible ringer for multiple deskset phones. A controller detects a flag message that precedes an incoming telephone call, and selects one or more frequencies based on a local expectation of a ringing telephone at the geographic location, or according to a user preference. A digital signal processor (DSP) generates a digital ringer signal based the selected frequencies. An audio code converts the digital ringer signal to an analog ringer signal and sends the analog ringer signal to multiple deskset phones using a receive cable. The analog ringer signal is amplified to drive a speaker that converts the analog ringer signal into an audible ringer sound at each deskset phone. The audible ringer sound can be customized for multiple geographic locations by modifying the selected frequencies used in the digital ringer signal.
