摘要:
A method and apparatus for a called subscriber to send a sound for his own personal information as a ringback tone with a ringback tone replacing sound are disclosed. The method comprises the steps of: HLR providing MSC with the first information about whether a ringback tone is to be replaced or not and the second information for routing to sound providing means when a called terminal is registered in MSC; MSC requesting a call connection to the sound providing means based on the first and second information when the called terminal is called; and the sound providing means call-connecting to the calling terminal, and providing the calling terminal with a specific sound, wherein the specific sound is generated by combining a subscriber information sound, which can identify the called subscriber or can represent the subscriber's character, with the ringback tone replacing sound.

Delay is measured associated with the transfer of voice signals involving a telephone connected to a PSTN carrier (e.g., non VoIP based) where the call is terminated by an operator agent using a workstation connected to a VoIP based network. A test tone is provided to the telephone causing a tone to be generated at a headset of the workstation. An oscilloscope measures the delay using an input of a first signal associated with the generation of the test tone at the telephone, and a second signal associated with the generation of the resulting tone at the headset. The tone at the headset can be looped back into the headset microphone, causing a return signal to be generated and measured. Once the overall delay is known, and the delay of certain elements are estimated, the delay associated with other network elements, including the workstation, can be determined.

A method for providing a call waiting notification to a participant in an existing telephone call includes the steps of establishing a telephone call with a calling party. A specified telephone number of the participant in the existing telephone call is received from the calling party. A distinctive call waiting tone is caused to be sent to the participant wherein the distinctive call waiting tone is specified with the calling party. Responsive to the participant electing to speak with the calling party, the established call is transferred to the participant. A system for providing a call waiting notification to a participant in an existing telephone call is also disclosed.
摘要:
A device and method for testing a telephone circuit in which a caller takes advantage of available caller identification information to complete a ringback test without resort to potentially costly and overused toll trunks. The ringback test device is accessed by a caller (subscriber or craftsperson) who may not be aware of the telephone number from which he is calling when the caller completes a call to a telephone number assigned to the device. As the caller is accessing the test device, the test device detects the caller identification available between the first and second rings to identify the caller's telephone number, and answers the call after the second ring. The test device presents the telephone number to the caller, and the test device may thereafter be used to complete a ringback test to the identified telephone number. The caller ID information may also be display-formatted at the test device and provided to a caller's visual display.

A method and apparatus for an editable personalized ring back tone service in a telephone communication is disclosed in the present invention. The apparatus may include a master content provider server storing at least one personalized ring back message, an internet data center connected to the master content provider server and a participating telephone service provider for retrieving the personalized ring back message when a called party is the subscriber and delivering the personalized ring back message to be heard by a calling party while connecting to the called party, and an authoring tool for generating and editing the personalized ring back message to be uploaded to the master content provider through a public website.

A method that uses a test system at one end of a communication link to test the communication link for high speed service by coupling the test system to the communication link, placing a telephonic call to telephonic equipment located at an other end of the communication link and testing the communication link with the test system after the call has been terminated at the telephonic equipment.
摘要:
A tone signal received in a telecommunications network is bandpass filtered based on an identified type of the received tone signal, providing a bandpass filtered tone signal. The tone signal is also bandstop filtered based on the identified type of the received tone signal, providing a bandstop filtered tone signal. The bandpass filtered tone signal and the bandstop filtered tone signal are analysed and the received tone signal is quantified based on the analysis result.
