Phone Communication Controlling Method - Patent 8150010
1. Field of the Invention The invention relates to a communication system, a method for controlling a communication system. 2. Description of the Related Art When a user makes a phone call, the user directly inputs a phone number of a person to be called to a sending terminal. Thus, the sending terminal performs a call operation. A sending terminal prestores a name associated with a phone number ina memory, a phonebook of the terminal. When a name of a person to whom the caller wishes to speak is input through a key operation, the terminal searches for a stored phone number associated with the name, and makes a call by using the phone numberobtained through the search operation. A technique related to the above techniques is disclosed in Japanese Laid-open Patent Publication No. 9-233187. In general, for example, when a call operation is performed, the phone numbers of a receiving terminal and a sending terminal are revealed by the users of the terminals. Accordingly, if the sending terminal sends its own phone number at acalling time, the receiving terminal can identify the sending terminal or the user of the sending terminal by using the sent phone number. Additionally, in general, when a sending terminal makes an anonymous call without revealing the phone number thereof to a receiving terminal, the sending terminal uses a "caller ID blocking service" provided by a common carrier and makes a call. However, in the related arts, the network identification information, a phone number of a sending terminal is not sent to a user of the receiving terminal. Accordingly, the user of the receiving terminal cannot disadvantageously identify thesending terminal. For instance, in the above-described example, since a receiving terminal identifies a sending by terminal using the receiving phone number of the sending terminal, the sending terminal reveals the phone number thereof to the user of thereceiving terminal. In addition, for example, in the technology using th
Path Redundant Hardware Efficient Communications Interconnect System - Patent 8150019
I. TECHNICAL FIELD The present invention relates methods and devices in the area of Telephony and Communication equipment and, more particularly to the "switching fabric" that may comprise the connection and servicing of copper pair and fiber optical crossconnectsamong other aspects such as are found in voice and data phone systems. Certain features of the invention may also be applicable to computer systems architectures, routers, and other data collection or transmission systems and where larger matrixes ofsignals or lines may be interconnected.II. BACKGROUND Since its inception, telephony has depended upon the use of pairs of copper wire, also referred to as "copper loop" or just "loop", as the main local area data transmission medium. Although cable, fiber optics, and wireless links likemicrowave, satellite, and cellular telephones have greatly enhanced communication access for the subscriber, they do not yet replace copper as the main transmission medium for hundreds of millions of individual applications. The existing "copper loop"infrastructure in place today represents an enormous investment in resource and time. Modern telephony requires connect, disconnect or modification of hundreds of thousands of services daily. Examples of such service changes are, connecting a new phone line for a subscriber's home, providing additional phone lines for abusiness, adding DSL or other high speed data link to an existing subscriber service, re-routing a phone line to bypass a faulty line, or disconnecting a phone service. Historically, when a subscriber requested a change in service, a repair or changeorder was generated to instruct a technician to make the required changes. Other applications can have similar needs. In some regards, connections may involve physical interconnects required to transmit the intended data or information. Connections may also be abstract in that they are internal to a computer, software manifested, or the like. Suchinterconnects may
Circuit Device With Serial Bus Isolation - Patent 8150028
FIELD The present disclosure is generally related to a circuit device with serial bus isolation, and more particularly, but not by limitation to, a subscriber line interface circuit having shared serial bus isolation.BACKGROUND Circuit devices often communicate data and control signals via serial buses, which may be bi-directional. In some instances, isolation circuitry may be provided to electrically isolate the circuit devices. One example of a circuit device thatuses isolated serial buses to communicate data is a subscriber line interface circuit (SLIC), which can be coupled to communication lines, such as tip and ring lines of a telephone network, to send and receive information via the network communicationlines. The SLIC may be adapted to communicate with another circuit via multiple pulse code modulation (PCM) buses and multiple serial peripheral interface (SPI) buses. Each bus typically includes an isolation circuit to electrically isolate the SLICfrom the other circuit. Such isolation circuits can include capacitors, transformers, optical isolation circuits, other isolation circuits, or any combination thereof. However, such isolation circuits can increase the overall cost of a device. Hence,there is a need for an improved communication interface between circuit devices.SUMMARY In a particular embodiment, a circuit device includes a first circuit having a first plurality of serial terminals including a first data receive terminal and a first data transmit terminal. The first plurality of serial terminals iscommunicatively coupled to a particular circuit via isolation circuitry to communicate first serial data. The circuit device further includes a second circuit having a second plurality of serial terminals including a second data receive terminal coupledto the first data transmit terminal and including a second data transmit terminal coupled to the first data receive terminal to communicate second serial data to the particular circuit via the firs
Method And System For Subscriber Line Interface Circuit - Patent 8150026
The present invention is directed to integrated circuits. More particularly, the invention provides a method and device for an integrated circuit for telecommunication applications. Merely by way of example, the invention has been applied tosubscriber line control circuits for interfacing with digital equipment in a central office. But it would be recognized that the invention has a much broader range of applicability. For example, embodiments of the invention can find application incommunication networks such as cable television networks, fiber optic, Ethernet port interface to the Internet, VoIP, and wireless local loop, etc. In a Plain Old Telephone Service (POTS) system, several functions are needed for telephony signaling, subscriber line supervision, and telephone equipment operations. These functions include battery feed, over voltage protection, ringing,supervision, codec, hybrid, and testing, etc. These electronic functions are collectively known by the acronym BORSCHT. BORSCHT circuitry is often found on a telecommunications network line card for implementation of a standard POTS telephone interfacefor digital equipment in a central office. With the advancement of integrated circuit technology, BORSCHT circuitry can be integrated into a chipset. For example, a line card may include a SLIC, or a subscriber line interface circuit, and a CODECcircuit. In a conventional design, the SLIC typically handles the analog functions and drives the telephone lines and usually include high voltage devices and circuits, whereas the CODEC typically handles digital signal processing and interfacefunctions. Some conventional line cards may include a SLIC integrated circuit and a CODEC integrated circuit. A conventional line card may also include certain discrete components such as switching relays, large capacitors, etc. These conventionaltechniques have many limitations. From the above, it is seen that an improved technique for subscriber line interface circuit
System And Method Of Phone Bridging - Patent 8150015
S None.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT Not applicable.REFERENCE TO A MICROFICHE APPENDIX Not applicable.BACKGROUND Conference bridging traditionally requires a party seeking to initiate a conference bridge session to pre-arrange the session with a third party service provider, often for a fixed call duration and with a set group of participants. It requiresparticipants to dial into a dedicated telephone number at a prearranged time and provide an access code. A call operator may be involved who may announce participants and monitor the bridge discussion. Parties initiating a conference bridge callgenerally incur a cost and participants phoning into the bridge may incur toll charges. Participants seeking to join must have at least the dial-in number, the access code and perhaps be on the pre-set list of participants to join a traditionalconference bridge and may otherwise be denied admission.SUMMARY In an embodiment, a method for providing a dynamic bridge service is provided. The method comprises provisioning a dynamic bridge service associated with at least a first private number and a second private number. The method also comprisesreceiving an origination attempt from an electronic device associated with a third private number to establish a call to an electronic device associated with the first private number, requesting the bridge to be opened in response to receiving theorigination attempt, and connecting the electronic device associated with the third private number to the bridge. The method also comprises connecting the electronic device associated with the first private number to the bridge, receiving a request tojoin the bridge from an electronic device associated with the second private number, and connecting the electronic device associated with the second private number to the bridge in response to receiving the request to join the bridge from the electronicdevice associated with the second private number. In anoth
Telephony Security System - Patent 8150013
The invention relates generally to telecommunications monitoring and/or control systems and particularly to a telephony resource and security management system for monitoring and/or controlling access between end-user stations and the publiccircuit-switched network and/or the public packet-switched network.BACKGROUND OF THE INVENTION Currently, there are telecommunication firewalls that operate on traditional circuit-switched networks, implementing a centrally managed, policy-based, enterprise-wide security policy, performing designated actions (such as allowing or denyingthe call, recording the call, redirecting the call, and monitoring the call for keywords), based on the determined attributes of a circuit-switched call (such as call direction, call source, call destination, and call type). U.S. patent applicationSer. No. 09/907,089 entitled TELEPHONY SECURITY SYSTEM describes a telecommunication firewall that operates on traditional circuit-switched networks. Unfortunately, there is no equivalent device for performing the same and similar tasks for VoIP (Voice over Internet Protocol) calls. Current IP firewalls are in place on the packet-switched network, but they deal with attributes of individualpackets, not attributes of the real-time packet-switched call itself. This is indeed unfortunate because a majority of the same call attributes determined on a circuit-switched call can also be determined on a real-time packet-switched call. Therefore, there is a need for a telephony security system and method that provides centrally managed, policy-based, enterprise-wide monitoring and/or control of incoming and outgoing real-time packet-switched calls between an enterprise'send-user station and the public packet-switched network, based on attributes of the call itself. Additionally, there is a need for a telephony security system and method that provides consolidated, central, policy-based, enterprise-wide monitoring and/or control of calls on both a circuit-swi
System And Method For Provisioning Connections As A Distributed Digital Cross-connect Over A Packet Network - Patent 8150018
TECHNICALFIELD This disclosure relates generally to communication systems, and more particularly to a system and method for provisioning a connection as a distributed digital cross-connect in a packet network.BACKGROUND A typical packet-based communication network can support communication sessions between two or more participants. For example, the network could support a voice telephone call by transporting Internet Protocol (IP) packets between a callingparty and a called party. The packets containing the voice information are typically routed between the parties through various network nodes in the packet network.SUMMARY This disclosure describes a system and method for provisioning a connection as a distributed digital cross-connect in a packet network. In one embodiment, a method includes receiving a request to provision a path associated with at least a portion of a packet network and determining whether a router is associated with the path in the packet network. The method also includesprovisioning a first connection between a first gateway and a second gateway when the router is not associated with the path. The method further includes provisioning a second connection between the first gateway and the router and a third connectionbetween the router and the second gateway when the router is associated with the path. In addition, the method includes at least one of associating and disassociating a first endpoint of the first gateway and a second endpoint of the second gateway withone or more of the connections. In another embodiment, a method includes detecting an addition of a first gateway to a packet network. The method also includes establishing a first connection between the first gateway and a router when the first gateway is of at least onegateway type. In addition, the method includes identifying a second gateway and establishing a second connection between the first gateway and the second gateway when the first gateway is of at least one other
Control Of Echo Cancellation Filters - Patent 8150027
This application claims priority from French Application FR 06 11485, filed Dec. 28, 2006, which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION The present invention relates to the control of echo cancellation filters. In numerous communication systems and equipment, a problem arises with echo, that is to say situations in which an acoustic signal is emitted and simultaneously, totally or partially acquired, and then played back to the initial emitter in theform of an echo. This type of situation occurs during communications implementing equipment comprising a loudspeaker for emitting an acoustic signal and a microphone situated within range of the loudspeaker such as compact or "hands-free" type equipment. Onaccount of the proximity between the loudspeaker and the microphone, the microphone is liable to acquire the signal emitted by the loudspeaker. Thus, a distant talker hears his own voice delayed by the lag introduced by the communication chain. In order to alleviate this problem, the terminals use echo cancellation filters. In a general manner, an echo is estimated on the basis of the signal emitted and is deducted from the microphone signal. In practice, this is often carried out by adaptive filters applied to the microphone signal. In a general manner, adaptive filtering consists in giving an expression for the evolution of coefficients of the filter over time, this expressionhaving to meet a convergence criterion. Several algorithms are used in echo cancellation such as, for example, the so-called LMS (Least Mean Square) or NLMS (Normalized LMS) algorithms or other algorithms that are well known to a person skilled in theart and described in particular in the document by Simon S. Haykin, "Adaptive Filter Theory", Prentice Hall (September 2001). In order to suitably filter the echo and not to introduce distortion in the signal played back, it is necessary to control the echo cancellation filters differently when there i
Methods And Systems For Setting A Volume Level Of Ringback Media Presented To A Calling Party - Patent 8150024
The present invention relates to presenting media content to a calling party and, more particularly, to setting a volume level of ringback media presented to a calling party.BACKGROUND In a traditional telephone network, ringback media is typically an audible tone sequence presented during a call process to a caller. The ringback media may signal to the caller that the called party's phone is being alerted of an incoming callfrom the caller to the called party. Upon hearing ringback media, the caller may generally assume that the called party is receiving a corresponding, concurrent (or nearly concurrent) alert, such as an audible ringtone sequence. The ringback mediausually continues until either the called party (or a call-handling function such as an answering machine) answers the call or the caller hangs up before the call is answered. The period within the call process during which ringback media is played istypically referred to as the ringback period. The model for ringback media has evolved similarly in both circuit-switched telephony with out-of-band signaling and services (Signaling System 7 (SS7) and Advanced Intelligent Network (AIN), for example), and packet-based telephony, such asVoice over Internet Protocol (VoIP). Ringback media in these types of systems is typically stored as an audio data file on a network entity such as a ringback server, and played out to a caller's phone during the call process when the entity receives asignal, from a terminating switch for example, indicating that the called party's phone is being alerted.SUMMARY Typically, ringback media is presented to a calling party at a baseline volume level. However, the baseline volume level of the ringback media may not always be a desirable level. For instance, when the calling party is in an environment withrelatively high ambient noise, the baseline volume level of the ringback media may be too low for the calling party to hear and/or understand the ringback media. In such
Automated System And Method For Distinguishing Audio Signals Received In Response To Placing And Outbound Call - Patent 8150023
The present invention relates to distinguishing audio signals received in response to placing an outbound call and, more particularly, to an automated system and method for analyzing the audio signal and taking one of a plurality of actionsbased on a characteristic of the audio signal.BACKGROUND OF THE INVENTION Automated dialing systems are often used to place telephone calls and then connect the called party to a resource only after the called party has answered the telephone. An advantage of using an automated dialing system is that the resource isnot expended manually dialing the call and waiting for the called party to answer the telephone. Further, if the line is busy or the called party does not answer the telephone after a predetermined number of rings--no resource time is expended on theunanswered call. One problem with automated dialing systems is that if an answering machine answers the call, the resource may be connected to the answering machine rather than the called party. To alleviate this problem, several systems have been developed for detecting whether a call has been answered by an answering machine or a person. For example, U.S. Pat. No. 5,371,787 to Hamilton uses a combination of a click detector, a ringdetector, a voice detector, click analyzer, ring analyzer, noise analyzer, answer analyzer, silence analyzer, and voice analyzer to distinguish whether a telephone was answered by an answering machine based on time intervals of voice and silence withinthe audio signal. Each of U.S. Pat. No. 5,430,792 to Jesurum et al., U.S. Pat. No. 5,724,420 to Torgrim, and U.S. Pat. No. 5,828,731 to Szlam et al. similarly distinguishes between the existence of voice and silence within the audio signal to determinewhether the telephone has been answered by an answering machine. In a separate field of technology, traditional ring back (e.g. a cadence of 2 seconds on, 4 seconds off in the US) is being replaced by customized ring back audio content. Fo
System And Method For Transitioning A Voice Session In Progress Over A Communication Network Into A Voice And Data Session - Patent 8150014
CROSS-REFERENCE TO RELATEDAPPLICATIONS Not Applicable.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is in the field of telephony communications including computer telephony integrated (CTI) systems and relates particularly to methods and apparatus for transitioning a voice-only telephone session to a voice plus datasession between at least two active parties. 2. Discussion of the State of the Art The field of telephony communications has experienced many technological improvements over the recent years relating to computer telephony integration (CTI), multiple party communications, intelligent routing, voice over Internet protocol, andend usability through enhanced features. Seamless bridging between traditional switched telephony and Internet protocol network telephony and accompanying standard protocols has enabled communication sessions and media transfer sessions that encompassend users operating a wide variety of communications devices. In typical enterprise communication, workers or associates have telephone extension numbers associated with an existing CTI-enabled PBX central office telephony switch. A caller off-hooks a telephone set, dials an extension to place a call andsome form of ringing event or notice of the incoming call and alerts the recipient. To answer the call, the recipient off-hooks a telephone set to accept the call. The physical nature of such a call is bi-directional voice over the connections betweeneach set and the PBX. Recent developments in telephony enable any user having a network-connected personal computer with a video display unit (VDU) running a graphical user interface (PC/GUI) and having a private branch exchange (PBX) telephone set, or publicswitched telephony network (PSTN)-connected telephone, or a cellular telephone, to initiate a voice and data session with any other users similarly equipped with a PC/GUI connected to the prevailing data network and a telephone. A commercially availables
Phone Dialer With Advanced Search Feature And Associated Method Of Searching A Directory - Patent 8150017
BACKGROUND While many communication devices such as conventional landline and cellular telephones include a keyboard for the input of a numeric telephone number, size constraints typically limit the number and arrangement of keys. Typically telephonesinclude a small numeric or "touch tone" keypad or dial pad configured according to international standard ITU E.161 established by the International Telecommunications Union (ITU) and/or according to ISO 9995-8 established by the InternationalOrganization for Standardization. The keypad layout includes 12 keys representing numerals 0-9 and the symbols "*" (called the "star key" or "asterisk key") and the. "#" (called the "octothorpe", "number sign", "pound key", or "hash key".) Thestandards provide for the assignment of the 26 letters A-Z to the number keys of a numeric keypad in support of, among other things, the entry of alphabetic or "alpha" characters. Because each key may represent a number in addition to three or four letters of, for example, the English alphabet, several technique have been used to determine the symbol (number or letter) that is being input or selected by a user. Onemethod known as "multi-tap" requires that a user depress a key a number of times corresponding to the order (or "ordinality") of the letter being selected. In one such scheme, the keypad may be operated either in a numeric input mode in which eachkeystroke is interpreted as the corresponding number or in an alpha mode in which the number of times a key is depressed is used to determine the letter being input. Another method known as predictive text may use a dictionary to match a sequence ofnumeric inputs to corresponding numeric codes of dictionary entries. For example, the name "BOB" would correspond to a numeric sequence of 2-6-2. The predictive method works relatively well for short text messages using a limited dictionary of words wherein ambiguity between dictionary entries based on their numeric equivalence is minimal.
System And Method For Prompt Modification Based On Caller Hang Ups In IVRs - Patent 8150020
The invention relates generally to call centers or other call processing systems utilizing Interactive Voice Response applications to process calls or distribute calls among a number of service agents for handling. More particularly, thepresent application relates to the detecting of user hang ups early in the call, correlating the number of hang ups to the number of hang ups for various versions of the same prompt or series of prompts, providing analysis of the hang up data such asidentifying where in the call users hang up, and automatically optimizing replacement prompt selection based on hang-up data.BACKGROUND OF THE INVENTION Interactive Voice Response (IVR) systems are computer-based telephony applications that answer calls from callers and, typically, attempt to automate calls or to route calls to appropriate human agents or other appropriate applications. Generally the system plays pre-recorded voice prompts to which a person responds by a) pressing a number on a telephone keypad to select an option, b) speaking simple answers such as "yes", "no", or numbers, c) speaking keyword responses to menus, or,even d) using unconstrained natural language in an open dialog. Automatic call distributor (ACD) systems are often the first point of contact when calling many larger businesses, and can be used in place of more expensive IVR systems. An ACD is a telephone facility that manages incoming calls and handlesthem based on the number called and an associated database of handling instructions. Many companies offering sales and service support use ACDs to validate callers, make outgoing responses or calls, forward calls to the right party, allow callers torecord messages, gather usage statistics, balance the queues of waiting calls to agent phone lines, and to provide other services. IVR systems are used to create and manage services such as telephone banking, order placement, caller identification and routing, balance inquiry, and airline ticket booking. IVR sys
Apparatus, Method, And Computer Program Product For Geographic Call Center Status And Security - Patent 8150011
BACKGROUND For many companies, call centers are becoming a globally delivered resource. These call centers usually rely on computer and telephone systems to provide the status, activity, security, work-force, and other information of each call center.

Providing Notifications Using Text-to-speech Conversion - Patent 8149995
COPYRIGHT RIGHTS A portion of the disclosure of this patent document contains material that is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as itappears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is related to notification methods and systems, and in particular, to electronic, networked notification systems. 2. Description of the Related Art Conventional notification systems intended for contacting known individuals, such as a company's employees, are often cumbersome to setup, operate and maintain. For example, many such notification systems have one or a few operators type in thename and phone numbers of all those to be included in a notification group, which can result in the time consuming task of typing hundreds or thousands of entries and can further result in many errors. In addition, while there have been recent advances in communication technologies, such as cell phones, two-way pagers, SMS messaging, instant messaging, and still other communication technologies, many conventional emergency notification systemsare unable to provide emergency notifications to one or more of the foregoing communication technologies. Therefore, emergency notifications, as well as other notifications, may not be communicated to a recipient as quickly or efficiently as desired. Further, many conventional notification systems do not track whether a notification was received and/or by which means of communication the notification was received. This can result in important notifications not being actually received by theappropriate individual, or repeated notifications being sent out unnecessarily. In addition, many conventional notification systems do not provide adequate or timely reporting of confirmations of notific
