AUDIX (AUDio Information EXchange) is a voicemail server intended to be used with a Lucent/Avaya private branch exchange (PBX). [1] AUDIX features many integrations with Avaya PBXes, such as capturing the extension of the calling party and announcing that person's name (if they're also an AUDIX subscriber and have recorded their name on the system) when announcing the attributes of a message, automatic identification of subscribers when they are dialing in to retrieve their messages, and activating and deactivating message-waiting indicators. [2]
It can also serve as a recording device. A subscriber with an appropriately administered feature button on their phone can press said button and within a few seconds, the station will be conferenced with AUDIX and AUDIX will record the conversation. The recording will be stored like a voice mail.
AUDIX systems are based on Unix, and share some software with Avaya's Conversant interactive voice response (IVR) platform. Early forms of unified messaging appeared in the late 1980s; earlier AUDIX releases interoperated with System V mail servers and with System 85 PBXes, when AT&T still owned UNIX. [3] Many of the same status and control programs are used to operate AUDIX and Conversant systems, but an AUDIX system is geared specifically to serving up voicemail and is not a general IVR platform.
The Simple Mail Transfer Protocol (SMTP) is an internet standard communication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages. User-level email clients typically use SMTP only for sending messages to a mail server for relaying, and typically submit outgoing email to the mail server on port 587 or 465 per RFC 8314. For retrieving messages, IMAP is standard, but proprietary servers also often implement proprietary protocols, e.g., Exchange ActiveSync.
Interactive voice response (IVR) is a technology that allows humans to interact with a computer-operated phone system through the use of voice and DTMF tones input via a keypad. In telecommunications, 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.
Microsoft Outlook is a personal information manager software system from Microsoft, available as a part of the Microsoft Office suite. Though primarily an email client, Outlook also includes such functions as calendaring, task managing, contact managing, note-taking, journal logging, and web browsing.
A voicemail system is a computer-based system that allows users and subscribers to exchange personal voice messages; to select and deliver voice information; and to process transactions relating to individuals, organizations, products, and services, using an ordinary phone. The term is also used more broadly to denote any system of conveying a stored telecommunications voice messages, including using an answering machine. Most cell phone services offer voicemail as a basic feature; many corporate private branch exchanges include versatile internal voice-messaging services, and *98 vertical service code subscription is available to most individual and small business landline subscribers.
A dialer or dialler is an electronic device that is connected to a telephone line to monitor the dialed numbers and alter them to seamlessly provide services that otherwise require lengthy National or International access codes to be dialed. A dialer automatically inserts and modifies the numbers depending on the time of day, country or area code dialed, allowing the user to subscribe to the service providers who offer the best rates. For example, a dialer could be programmed to use one service provider for international calls and another for cellular calls. This process is known as prefix insertion or least cost routing. A line powered dialer does not need any external power but instead takes the power it needs from the telephone line.
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.
In software architecture, publish–subscribe is a messaging pattern where senders of messages, called publishers, do not program the messages to be sent directly to specific receivers, called subscribers, but instead categorize published messages into classes without knowledge of which subscribers, if any, there may be. Similarly, subscribers express interest in one or more classes and only receive messages that are of interest, without knowledge of which publishers, if any, there are.
Google Talk was an instant messaging service that provided both text and voice communication. The instant messaging service was variously referred to colloquially as Gchat, Gtalk, or Gmessage among its users.
The Meridian Norstar, later called Nortel Norstar was a small-office digital key telephone system introduced by Northern Telecom and now sold by Avaya. It is based on the same internal design and instruction set as Nortel's earlier SL-1 and DMS systems, allowing it to support features such as integrated voice messaging, automatic call distribution and other features, but possibly supporting a total of up to 192 phones and with limited processing power. In the United Kingdom it is sold by British Telecom, rebadged as the BT Norstar.
Voice broadcasting is a mass communication technique, begun in the 1990s, that broadcasts telephone messages to hundreds or thousands of call recipients at once. This technology has both commercial and community applications. Voice broadcast users can contact targets almost immediately. When used by government authorities, it may be known as an emergency notification system.
Gordon Matthews was an American inventor and businessman and started one of the first companies which pioneered the commercialization of voicemail.
FreeSWITCH is a free and open-source application server for real-time communication, WebRTC, telecommunications, video and Voice over Internet Protocol (VoIP). Multiplatform, it runs on Linux, Windows, macOS and FreeBSD. It is used to build PBX systems, IVR services, videoconferencing with chat and screen sharing, wholesale least-cost routing, Session Border Controller (SBC) and embedded communication appliances. It has full support for encryption, ZRTP, DTLS, SIPS. It can act as a gateway between PSTN, SIP, WebRTC, and many other communication protocols. Its core library, libfreeswitch, can be embedded into other projects. It is licensed under the Mozilla Public License (MPL), a free software license.
Visual voicemail is direct-access voicemail with a visual interface. Such an interface presents a list of messages for playback, as opposed to the sequential listening required using traditional voicemail, and may include a transcript of each message. In 2007, Apple's iPhone was the first cell phone promoting this feature.
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.
Fixed–mobile convergence (FMC) is a change in telecommunications that removes differences between fixed and mobile networks.
