A voicemail system (also known as voice message or voice bank) is a computer-based system that allows people to leave a recorded message when the recipient is unable to answer the phone. The caller is prompted to leave a message and the recipient can retrieve said message at a later time.
Voicemail can be used for personal calls and more complex systems exist for companies and services to handle customer requests. The term is also used more broadly to denote any system of conveying stored telecommunications voice messages, including using an answering machine.
Features
Drawing of how the voicemail system interacts with the PBX
Voicemail systems are designed to convey a caller's recorded audio message to a recipient. To do so they contain a user interface to select, play, and manage messages; a delivery method to either play or otherwise deliver the message; and a notification ability to inform the user of a waiting message. Most systems use phone networks, either cellular- or landline-based, as the conduit for all of these functions. Some systems may use multiple telecommunications methods, permitting recipients and callers to retrieve or leave messages through multiple methods such as PCs or smartphones.
Simple voicemail systems function as a remote answering machine using touch-tones as the user interface. More complicated systems may use other input devices such as voice or a computer interface. Simpler voicemail systems may play the audio message through the phone, while more advanced systems may have alternative delivery methods, including email or text message delivery, message transfer and forwarding options, and multiple mailboxes.
Almost all modern voicemail systems use digital storage and are typically stored on computer data storage. Notification methods also vary based on the voicemail system. Simple systems may not provide active notification at all, instead requiring the recipient to check with the system, while others may provide an indication that messages are waiting.
More advanced systems may be integrated with a company's PABX, with a call center ACD for automatic call distribution; with mobile or paging terminals for message alert; and computer systems/data bases for delivering information or processing orders. Interactive voice response (IVR) systems may use digital information stored in a corporate data base to select pre-recorded words and phrases stored in a voicemail vocabulary to form sentences that are delivered to the caller.
History
A common icon to represent voicemail (an abstraction of cassette tape, which were historically popular for use in voicemail recording before the 2000s)
The term Voicemail was coined by Televoice International (later Voicemail International, or VMI) for their introduction of the first US-wide Voicemail service in 1980. Although VMI trademarked the term, it eventually became a generic term for automated voice services employing a telephone. Voicemail popularity continues today with Internet telephone services such as Skype, Google Voice and ATT that integrate voice, voicemail and text services for tablets and smartphones.
Voicemail systems were developed in the late 1970s by Voice Message Exchange (VMX). They became popular in the early 1980s when they were made available on PC-based boards.[1] In September 2012 a report from USA Today and Vonage claimed that voicemail was in decline. The report said that the number of voicemail messages declined eight percent compared to 2011.[2][3]
The conventional solution to efficient handling of telephone communication in businesses was the "message center". A message center or "message desk" was a centralized, manual answering service inside a company staffed by a few operators who answered all incoming phone calls. Extensions that were busy or rang "no answer" would forward to the message center using a device called a "call director". The call director had a button for each extension in the company which would flash when that person's extension forwarded to the message center. A little label next to the button told the operator the person being called.
While it was an improvement over basic multi-line systems, the message center had many disadvantages. Many calls would come in simultaneously at peak periods, such as lunch time, and operators were often busy. This left message attendants with little time to take each message accurately. Often, they were not familiar with employees' names and "buzzwords" and how to spell or pronounce them. Messages were scribbled on pink slips and distributed by the internal mail system and messages, often arrived at people's desks after lengthy delays, contained little content other than the caller's name and number, and were often inaccurate, with misspelled names and wrong phone numbers.
Tape-based telephone answering machines had come into the residential telephone market, but they were not used much in the corporate environment due to physical limitations of the technology. One answering machine was needed for each telephone; messages could not be recorded if the user was using the phone; messages had to be retrieved in sequential order; and messages could not be retrieved remotely, selectively discarded, saved, or forwarded to others. Further, the manufacturers of PBXs (private branch exchanges—the name for corporate phone systems) used proprietary digital phone sets in order to increase the functionality and value of the PBX. These phone sets were, by design, incompatible with answering machines.
In the 1970s and early 1980s, the cost of long-distance calling decreased and more business communications were conducted by telephone. As corporations grew and labor rates increased, the ratio of secretaries to employees decreased. With more communication by phone, multiple time zones, and fewer secretaries, real-time phone communications were hampered by callers being unable to reach people. Some early studies showed that only 1 in 4 phone calls resulted in a completed call and half the calls were one-way in nature (that is, they did not require a conversation). This happened because people were either not at work (due to time zone differences, being away on business, etc.), or if they were at work, they were on the phone, away from their desks in meetings, on breaks, etc. This bottleneck hindered the effectiveness of business activities and decreased both individual and group productivity. It also wasted the caller's time and created delays in resolving time-critical issues.
Invention
The first public records describing voice recording were reported in a New York newspaper and the Scientific American in November 1877. Thomas A. Edison had announced the invention of his "phonograph" saying "the object was to record telephone messages and transmit them again by telephone." Edison applied for a US patent in December 1877 and shortly thereafter demonstrated the machine to publishers, the US Congress and President Rutherford B. Hayes. In an article outlining his own ideas of the future usefulness of his machine Edison's list began with "Letter writing, and all kinds of dictation without the aid of a stenographer." In other words, "voice messages" or "Voice-mail". By 1914, Edison's phonograph business included a dictating machine (the Ediphone) and the "Telescribe", a machine combining the phonograph and the telephone, which recorded both sides of telephone conversations.[4]
For nearly one hundred years, there were few innovations or advances in telephone services. Voicemail was the result of innovations in telephone products and services made possible by developments in computer technology during the 1970s. These innovations began with the Motorola Pageboy, a simple "pager" or "beeper" introduced in 1974 that was generally offered in conjunction with answering services that handled busy/ no-answer overloads and after hours calls for businesses and professionals. Operators wrote down a caller's message, sent a page alert or "beep" and when the party called back, an operator dictated the message.
With the introduction of "voice" pagers, like the Motorola Pageboy II operators could transmit a voice message directly to the pager and the user could hear the message. However, messages arrival was often untimely and privacy issues, as well as the high cost, eventually caused the demise of these services. By the mid 1970s digital storage and analog to digital conversion devices had emerged and paging companies began handling client messages electronically. Operators recorded a short message (five to six seconds, e.g. "please call Mr. Smith") and the messages were delivered automatically when the client called the answering service. It would only take a short step for the first voicemail application to be born.
Computer manufacturers, telephone equipment manufacturers, and software firms began developing more sophisticated solutions as more powerful and less expensive computer processors and storage devices became available. This set the stage for a creation of a broad spectrum of computer based Central Office and Customer Premises Equipment that would eventually support enhanced voice solutions such as voicemail, audiotex, interactive voice response (IVR) and speech recognition solutions that began emerging in the 1980s. However, broad adoption of these products and services would depend on the global proliferation of touch tone phones and mobile phone services which would not occur until the late 1980s.
Inventor controversy
Many contributed to the creation of the modern-day voicemail. Legal battles ensued for decades.[5] The true first inventor[citation needed] of voicemail, patent number 4,124,773 (Audio Storage and Distribution System), is Robin Elkins.[6] "Though Elkins received a patent in 1978, telecommunications giants began offering voicemail without paying Elkins a penny in royalties."[7] "Elkins never expected to spend 10 years of his life battling some of the world's largest corporations, either. But once he patented his system, he figured he should protect it."[8] Later, Elkins successfully licensed his patented technology to IBM, DEC, and WANG, among many others. Unfortunately, his patent did not address simultaneity of voice message access and storage and the application for patent was filed after the patent application of the system patented by Kolodny and Hughes, as described below.
Early applications
One of the first modern day voicemail applications was invented by Gerald M. Kolodny and Paul Hughes, which was described in an article in the medical journal, Radiology (Kolodny GM, Cohen HI, Kalisky A. Rapid-access system for radiology reports: a new concept. Radiology. 1974;111(3):717–9) A patent was applied for by Kolodny and Hughes in 1975, prior to the patent applications of both Elkins and Matthews and was issued in 1981 (US patent 4,260,854). The patent was assigned to Sudbury Systems of Sudbury Massachusetts who proceeded to market and sell such systems to corporations and hospitals. IBM, Sony and Lanier, as well as several smaller makers of voicemail systems, licensed the Sudbury patent for their voicemail systems. A patent suit, brought by Pitney Bowes, claiming prior art to the Sudbury patent, was denied by the US District Court, District of Connecticut on November 8, 2000. A similar suit brought byVDI Technologies against the Kolodny and Hughes patent claiming prior art was dismissed by the US District Court in New Hampshire on December 19, 1991.
ADS used the human voice and the fixed-line touch-tone telephones that predated computer screens and mobile phones. The first operational prototypes were used by 750 IBM executives mainly in the US for their daily work. Those prototypes ran on an IBM System/7 computer attached to an IBM VM370 for additional storage.
In 1978 the prototype was converted to run on an IBM Series/1 computer. In September 1981 IBM started marketing ADS in America and Europe: the first customer installation was completed in February 1982.
ADS,[10] marketed by IBM and briefly by AT&T Corporation, was well featured for voice messaging, the result of IBM's considerable human-factors research plus observation of operational use. Using a 1980s computer requiring air conditioning, it was expensive and physically large. With further development it grew to handle up to 3000 users, 100 hours of messages, multiple languages, message notification to a host computer, and 16 simultaneous users.[11]
ADS could be connected to exchange lines and private exchanges including the IBM 2750 and 3750 Switching Systems available in Germany, France, Italy, Belgium, and the UK.
Another company, Delphi Communications of California, deserves some partial credit for invention of voicemail. Delphi developed a proprietary system called Delta 1 that picked up and coming calls directly from the telephone company. Delphi presented the concept publicly to the association of Telephone Answering Services around 1973 and the prototype system was launched in San Francisco in 1976 by a Delphi company called VoiceBank. A patent was applied for and issued for Delphi's Automated Telephone Voice Service System. The patent, US Patent No. 4,625,081, was issued after Delphi's closure, but Delphi's assets (and the patent) were transferred to another Exxon company, Gilbarco, which made equipment for gas pumps at filling stations. Gilbarco is now owned by GEC in the United Kingdom.[citation needed]
AT&T
AT&T developed a system called 1A Voice Storage System to support custom services including voicemail for the public telephone system.[13] It worked in conjunction with the companies 1A ESS and 5ESS systems. Development started in mid-1976,[14] with first deployment in early 1979. Friendly user service started in March 1980. The service was terminated in 1981 as a result of the US FCC Computer Inquiry II, which prohibited enhanced services from being provided by the regulated network.
VMX
In 1979, a company was founded in Texas by Gordon Matthews called ECS Communications (the name was later changed to VMX, for Voice Message exchange). VMX developed a 3000-user voice messaging system called the VMX/64. Matthews, a prolific entrepreneur and patentor, applied for and was granted a patent on voicemail (patent number 4,371,752) which issued in February 1983. The patent was promoted as the pioneering patent for voicemail. However, the patent application was filed on November 26, 1979, five years after, and issued in 1983.
VMX asserted infringement first with IBM, AT&T and then Wang, but all three companies reportedly would have been able to invalidate the patent on the basis of prior art and their licenses from Sudbury Systems Inc, for their Kolodny and Hughes patent.
IVR Voice Recognition
In 1985, Voice Response Inc. (formerly Call-It Co) a subsidiary of Lee Enterprises, Davenport IA, entered the fast-growing Interactive Voice (IVR) response market under the direction of Bob Ross, President.[15] About a year later, VRI introduced one of the first "successful" IVR applications that utilized voice recognition (rather than touch tone) to capture caller responses. Voice recognition technology had great difficulty with regional and ethnic differences and nuances which resulted in a high incidence of error. VRI discovered that hesitation (delayed response) signaled caller confusion or misunderstanding which often resulted in an inaccurate response. VRI developed proprietary techniques that measured user response times and used the data to make real-time changes to the application's dialog with the caller. VRI found that the confidence level of a "suspect" caller response could be increased by asking "Did you say (Chicago), Yes or No", a standard question heard in order taking or reservation making IVR applications today. VRI pioneering applications, including subscription fulfillment for Time and Life magazines, proved faster and less expensive than call centers using live operators and although VRI did not survive, their voice recognition processes became industry standards and VRI's patent USPTO – patent RE34,587 was eventually licensed by Intel/Dialogic and Nuance.
PC-based Voicemail
Amidst the booming popularity of the IBM PC-AT, a variety of companies popped up to market add-in boards to the AT. These companies aimed to use the PC as an inexpensive hardware platform for hosting add-in boards and software providing voice mail functionality for small businesses that wanted something more sophisticated than an answering machine but could not afford pricey conventional voice mail solutions. Among these was The Complete PC, founded in 1986 in Silicon Valley.[16] The Complete PC was sold to publicly-listed Florida-based Boca Research Inc., in 1993.[17]
International Voicemail Association
In 1987, voicemail service providers in the US and Europe joined to form the Voice Mail Association of Europe (VMA) with René Beusch, Radio-Suisse and Paul Finnigan, Finnigan USA[18] serving as VMA Chairman and President respectively. The first VMA meeting was held in Stockholm Huddinge by Voicemail Svenska AB in 1987, organized by its founder Lars Olof Kanngard. The tech team in Voicemail Svenska AB was granted the right to port the Voicemail from PDP systems to their own PC-board solution, which become known as the MiniVoice, later become ESSELTE VOICE AB. The VMA invited service providers, vendors and consultants to attend semi-annual conferences that included presentations, discussions and reporting of experiences. VMA membership was eventually expanded to include representatives from telecommunication organizations worldwide and became "The International Voice-mail Association". By the late 1980s, the Bell Operating companies, Tigon and other independent service providers in the US had joined the VMA. In 1992, VMA members conducted an "Information Week Tour of the U.S.", sharing ideas with major telecom operators. VMA working groups promoted collaboration and adoption of industry standards to the ITU and CCITT and at the 1999 CCITT conference in Geneva, Switzerland, demonstrated worldwide exchange of messages between the major voicemail vendors' platforms using the VPIM networking standard. Beusch and Finnigan led the VMA until 1998 and 1999 respectively and the organization continues to serve the voice services industry today.[19]
Public telephone services
In the US, the Bell Operating Companies and their cellular divisions had been prohibited by the FCC from offering voicemail and other enhanced services such as paging and telephone answering services (no such prohibition existed in foreign countries). A ruling by Judge Harold H. Greene on March 7, 1988, removed this barrier and allowed the BOCs to offer voicemail service, however, they were not allowed to design or manufacture equipment used to provide voicemail services.[citation needed]
The opportunity created by the Greene decision, plus Voicemail International's abandonment of its market lead for carrier-grade systems, created a new opportunity for competing manufacturers and those who had been focusing on the corporate market. Unisys, Boston Technology, and Comverse Technology were quick to address the BOC and PTT marketplace. Octel, who had high capacity systems in use internally by all seven Regional Bell Operating companies, launched a new generation of its large system specifically designed for carriers and was compliant with "NEBS standards", the tight standard required by phone companies for any equipment located in their central offices.
Unified Messaging integrated voicemail into Microsoft Exchange, the corporate email system made by Microsoft. Unified Messaging had been invented by Roberta Cohen, Kenneth Huber and Deborah Mill at AT&T Bell Labs. The patent for Unified Messaging was received in June 1989 (Patent number 4,837,798).
Unified Messaging allowed users to access voicemail and email messages using either the graphical user interface (GUI) on their PC, or using the telephone user interface (TUI). For voicemail, they'd see the "header information" (sender, date sent, size, and subject). Users could double-click a voicemail from their email inbox and hear the message through their PC or a phone next to their desk. Voice messages could be sent using email or telephone addressing schemes, and the data networking infrastructure was used to send messages between locations rather than the public switched telephone network.
Other interesting markets developed from the carrier market including a concept called "virtual telephony". Virtual Telephony, developed by Octel, used voicemail to provide phone service rapidly in emerging countries without wiring for telephones. The problem this solved was that emerging countries did not have many telephones. Wiring for telephones was very expensive, and many poorer citizens did not have homes to wire. The economies of emerging countries were held back partly because people could not communicate beyond the area where they could walk or ride a bicycle. Giving them phones was one way to help their economies, but there was not a practical way to do it. In some countries, the wait for a phone was several years and the cost was in the thousands of dollars. Cellular phones were not an option at the time because they were extremely expensive (thousands of dollars per handset) and the infrastructure to install cell sites was also costly.
With virtual telephony, each person could be given a phone number (just the number, not the phone) and a voice mailbox. The citizen would also be given a pager. If someone called the phone number, it never rang on an actual phone, but would be routed immediately to a central voicemail system. The voicemail system answered the call and the caller could leave a long, detailed message. As soon as the message was received, the voicemail system would trigger the citizen's pager. When the page was received, the citizen would find a pay phone and call in to pick up the message. This concept was used successfully in South America and South Africa.
Instant messaging in voice
By the year 2000, voicemail had become a ubiquitous feature on phone systems serving companies, cellular and residential subscribers. Cellular and residential voicemail continue today in their previous form, primarily simple telephone answering. Email became the prevalent messaging system, email servers and software became quite reliable, and virtually all office workers were equipped with multimedia desktop PCs.
The increase in wireless mobility, originally through cellular services and today through IP-based Wi-Fi, was also a driver for messaging convergence with mobile telephony. Today,[as of?] it is not only fostering the use of speech user interfaces for message management, but increasing the demand for retrieval of voice messages integrated with email. It also enables people to reply to both voice and email messages in voice rather than text. New services, such as GotVoice, SpinVox and YouMail, are helping to blur the boundaries between voicemail and text by delivering voicemails to mobile phones as SMS text messages.
The next development in messaging was in making text messaging real-time, rather than just asynchronous store-and-forward delivery into a mailbox. Although in the 1980s Minitel in France was extremely popular and Teletext was widely used in the US, instant messaging on the Internet began with the ICQ application developed in 1996 as a public Internet-based free text "chat" service for consumers, but soon was being used by business people as well. It introduced the concept of Internet Protocol "presence management" or being able to detect device connectivity to the Internet and contact recipient "availability" status to exchange real-time messages, as well as personalized "Buddy list" directories to allow only people you knew to find out your status and initiate a real-time text messaging exchange with you. Presence and Instant Messaging has since evolved into more than short text messages, but now can include the exchange of data files (documents, pictures) and the escalation of the contact into a voice conversational connection.
Unified messaging with VoIP
Voicemail indication
Corporate voicemail did not change much until the advent of Voice over IP (VoIP—voice being transmitted over the internet) and the development of Internet Protocol (IP) telephony applications to replace legacy PBX telephony (called TDM technologies). IP telephony changed the style and technology of PBXs and the way voicemail systems integrated with them. This, in turn, facilitated a new generation of Unified Messaging, which is now likely to catch on widely. The flexibility, manageability, lower costs, reliability, speed, and user convenience for messaging convergence is now possible where it was not before. This might include intra- and inter-enterprise contacts, mobile contacts, proactive application information delivery, and customer contact applications.
The corporate IP telephony-based voicemail customer premises equipment market is served by several vendors including Avaya, Cisco systems, Adomo, Interactive Intelligence, Nortel, Mitel, 3Com, and AVST.[20] Their marketing strategy will have to address the need to support a variety of legacy PBXs as well as new Voice over IP as enterprises migrate towards converging IP-based telecommunications. A similar situation exists for the carrier market for voicemail servers, currently dominated by Comverse Technology, with some share still held by Lucent Technologies.
VoIP telephony enables centralized, shared servers, with remote administration and usage management for corporate (enterprise) customers. In the past, carriers lost this business because it was far too expensive and inflexible to have remote managed facilities by the phone company. With VoIP, remote administration is far more economical. This technology has re-opened opportunities for carriers to offer hosted, shared services for all forms of converged IP telecommunications, including IP-PBX and voicemail services. Because of the convergence of wired and wireless communications, such services may also include support of a variety of multi-modal handheld and desktop end user devices. This service, when offered for multiple extensions or phone numbers is sometimes also called Unified Voice-mail.
Benefits
Voicemail's introduction enabled people to leave lengthy, secure and detailed messages in natural voice, working hand-in-hand with corporate phone systems. The adoption of voicemail in corporations improved the flow of communications and saved huge amounts of money. GE, one of the pioneer adopters of voicemail in all of its offices around the world, claimed that voicemail saved, on average, over US$1,100 per year per employee. Needless to say, the ability to tell someone something without talking to them, can be a powerful reason to choose voicemail for delivery of a particular message.
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from Greek: τῆλε and φωνή, together meaning distant voice. A common short form of the term is phone, which came into use early in the telephone's history. Nowadays, phones are almost always in the form of smartphones or mobile phones, due to technological convergence.
An automated call distribution system, commonly known as automatic call distributor or automatic call dispatcher (ACD), is a telephony device that answers and distributes incoming calls to a specific group of terminals or agents within an organization. ACDs direct calls based on parameters that may include the caller's telephone number, the number they dialed, the time of day or a response to an automated voice prompt. Advanced ACD systems may use digital technologies such as computer telephony integration (CTI), computer-supported telecommunications applications (CSTA) or IVR as input to determine the route to a person or voice announcement that will serve the caller. Experts claim that "the invention of ACD technology made the concept of a call centre possible."
Telephony is the field of technology involving the development, application, and deployment of telecommunication services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone.
Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for voice calls for the delivery of voice communication sessions over Internet Protocol (IP) networks, such as the Internet.
Interactive voice response (IVR) is a technology that allows telephone users to interact with a computer-operated telephone system through the use of voice and DTMF tones input with a keypad. In telephony, IVR allows customers to interact with a company's host system via a telephone keypad or by speech recognition, after which services can be inquired about through the IVR dialogue. IVR systems can respond with pre-recorded or dynamically generated audio to further direct users on how to proceed. IVR systems deployed in the network are sized to handle large call volumes and also used for outbound calling as IVR systems are more intelligent than many predictive dialer systems.
Computer telephony integration, also called computer–telephone integration or CTI, is a common name for any technology that allows interactions on a telephone and a computer to be coordinated. The term is predominantly used to describe desktop-based interaction for helping users be more efficient, though it can also refer to server-based functionality such as automatic call routing.
Caller identification is a telephone service, available in analog and digital telephone systems, including voice over IP (VoIP), that transmits a caller's telephone number to the called party's telephone equipment when the call is being set up. The caller ID service may include the transmission of a name associated with the calling telephone number, in a service called Calling Name Presentation (CNAM). The service was first defined in 1993 in International Telecommunication Union – Telecommunication Standardization Sector (ITU-T) Recommendation Q.731.3.
An answering machine, answerphone, or message machine, also known as telephone messaging machine in the UK and some Commonwealth countries, ansaphone or ansafone, or telephone answering device (TAD), is used for answering telephone calls and recording callers' messages.
A telecommunications relay service, also known as TRS, relay service, or IP-relay, or Web-based relay service, is an operator service that allows people who are deaf, hard of hearing, deafblind, or have a speech disorder to place calls to standard telephone users via a keyboard or assistive device. Originally, relay services were designed to be connected through a TDD, teletypewriter (TTY) or other assistive telephone device. Services gradually have expanded to include almost any real-time text capable technology such as a personal computer, laptop, mobile phone, PDA, and many other devices. The first TTY was invented by deaf scientist Robert Weitbrecht in 1964. The first relay service was established in 1974 by Converse Communications of Connecticut.
Asterisk is a software implementation of a private branch exchange (PBX). In conjunction with suitable telephony hardware interfaces and network applications, Asterisk is used to establish and control telephone calls between telecommunication endpoints such as customary telephone sets, destinations on the public switched telephone network (PSTN) and devices or services on voice over Internet Protocol (VoIP) networks. Its name comes from the asterisk (*) symbol for a signal used in dual-tone multi-frequency (DTMF) dialing.
In telephony, an automated attendant allows callers to be automatically transferred to an extension without the intervention of an operator/receptionist. Many AAs will also offer a simple menu system. An auto attendant may also allow a caller to reach a live operator by dialing a number, usually "0". Typically the auto attendant is included in a business's phone system such as a PBX, but some services allow businesses to use an AA without such a system. Modern AA services can route calls to mobile phones, VoIP virtual phones, other AAs/IVRs, or other locations using traditional land-line phones or voice message machines.
VoIP spam or SPIT is unsolicited, automatically dialed telephone calls, typically using voice over Internet Protocol (VoIP) technology.
A business telephone system is a telephone system typically used in business environments, encompassing the range of technology from the key telephone system (KTS) to the private branch exchange (PBX).
PhoneValet Message Center is a discontinued Mac-based multi-line computer-telephony software application from Parliant Corporation. The application provided computer-telephony functionality including voicemail, call recording, and the maintenance of a call history. The system is a combination of software and hardware. PhoneValet was awarded an Eddy award for 2006.
Gordon Matthews was an American inventor and businessman and started one of the first companies which pioneered the commercialization of voicemail.
Google Voice is a telephone service that provides a U.S. phone number to Google Account customers in the U.S. and Google Workspace customers in Canada, Denmark, France, the Netherlands, Portugal, Spain, Sweden, Switzerland, the United Kingdom and the contiguous United States. It is used for call forwarding and voicemail services, voice and text messaging, as well as U.S. and international calls. Calls are forwarded to the phone number that each user must configure in the account web portal. Users can answer and receive calls on any of the phones configured to ring in the web portal. While answering a call, the user can switch between the configured phones. Subscribers in the United States can make outgoing calls to domestic and international destinations. The service is configured and maintained by users in a web-based application, similar in style to Google's email service Gmail, or Android and iOS applications on smartphones or tablets.
Unified communications (UC) is a business and marketing concept describing the integration of enterprise communication services such as instant messaging (chat), presence information, voice, mobility features, audio, web & video conferencing, fixed-mobile convergence (FMC), desktop sharing, data sharing, call control and speech recognition with non-real-time communication services such as unified messaging. UC is not necessarily a single product, but a set of products that provides a consistent unified user interface and user experience across multiple devices and media types.
eVoice is a telecommunications service owned by j2 Global, Inc. (NASDAQ:JCOM). The company manages incoming and outgoing calls using virtual phone numbers. The service was initially founded by Wendell Brown, Mark Klein, and Craig Taro Gold in 2000 and re-launched in March 2010 with an expansion of services that include both individual, personal uses as well as services for businesses.
A softphone is a software program for making telephone calls over the Internet using a general purpose computer rather than dedicated hardware. The softphone can be installed on a piece of equipment such as a desktop, mobile device, or other computer and allows the user to place and receive calls without requiring an actual telephone set. Often, a softphone is designed to behave like a traditional telephone, sometimes appearing as an image of a handset, with a display panel and buttons with which the user can interact. A softphone is usually used with a headset connected to the sound card of the PC or with a USB phone.
SunComm Technology is a Taiwan multinational computer technology and GSM Voice over IP gateway manufacturer. The main products in 2010 focused on GSM VoIP gateways & IP surveillance camera devices. Core members have been engaging in the communication & networks industry since 1977.
