IP-PBX
An IP PBX ("Internet Protocol private branch exchange") is a system that connects telephone extensions to the public switched telephone network (PSTN) and provides internal communication for a business. An IP PBX is a PBX system with IP connectivity and may provide additional audio, video, or instant messaging communication utilizing the TCP/IP protocol stack. Voice over IP (VoIP) gateways can be combined with traditional PBX functionality to allow businesses to use their managed intranet to help reduce long distance expenses and take advantage of the benefits of a single network for voice and data ( converged network). An IP PBX may also provide CTI features. An IP PBX can exist as a physical hardware device or as a software platform. Function IP PBX is primarily a software hosted on a regular desktop or server as per the requirement demands based on the expected traffic & criticality. Till 2019 IP PBX were deployed primarily as inbound and outbound call center solutions for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Business Telephone System
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). A business telephone system differs from an installation of several telephones with multiple central office (CO) lines in that the CO lines used are directly controllable in key telephone systems from multiple telephone stations, and that such a system often provides additional features for call handling. Business telephone systems are often broadly classified into key telephone systems and private branch exchanges, but many combinations (hybrid telephone systems) exist. A key telephone system was originally distinguished from a private branch exchange in that it did not require an operator or attendant at a switchboard to establish connections between the central office trunks and stations, or between stations. Technologically, private branch exchanges share lineage with central ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asterisk (PBX)
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. Asterisk was created in 1999 by Mark Spencer of Digium, which, since 2018, has been a division of Sangoma Technologies Corporation.

Internet Protocol
The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. IP has the task of delivering Packet (information technology), packets from the source Host (network), host to the destination host solely based on the IP addresses in the packet Header (computing), headers. For this purpose, IP defines packet structures that encapsulation (networking), encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information. IP was the connectionless datagram service in the original ''Transmission Control Program'' introduced by Vint Cerf and Bob Kahn in 1974, which was complemented by a connection-oriented service that became the basis for the Transmission Control Protocol (TCP). The Internet protocol suite is therefore often referre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cloud Communications
Cloud communications are Internet-based voice and data communications where telecommunications applications, switching and storage are hosted by a third-party outside of the organization using them, and they are accessed over the public Internet. Cloud services is a broad term, referring primarily to data-center-hosted services that are run and accessed over an Internet infrastructure. Until recently, these services have been data-centric, but with the evolution of VoIP (voice over Internet protocol), voice has become part of the cloud phenomenon.Arnold, Jon"Why businesses need to think differently about cloud communications" ''Focus'', April 16, 2010. Cloud telephony (also known as hosted telephony) refers specifically to voice services and more specifically the replacement of conventional business telephone equipment, such as a private branch exchange (PBX), with third-party VoIP service.

Trixbox
trixbox (formerly Asterisk@Home) was a software PBX based on Asterisk. trixbox was initially released under the name Asterisk@Home. In October 2006 it was renamed to trixbox after Digium requested that its developers cease the use of the word "Asterisk"; the renaming was further justified by the fact that the product at that time consisted of much more than just Asterisk. Versions trixbox CE (end of life) trixbox CE, the community edition founded by Kerry Garrison and Andrew Gillis, was completely free and was available under a GPLv2 license. It has been downloaded more than any other Asterisk-based PBX system according to SourceForge, with over two million downloads as of August 22, 2009. trixbox CE was last updated with a beta release, and shortly after a blog post was made by Andrew Gillis, founder & leader of development stating he was leaving.

Jingle (protocol)
Jingle is an extension to XMPP (Extensible Messaging and Presence Protocol) which adds peer-to-peer (P2P) session control (signaling) for multimedia interactions such as in Voice over IP (VoIP) or videoconferencing communications. It was designed by Google and the XMPP Standards Foundation. The multimedia streams are delivered using the Real-time Transport Protocol (RTP). If needed, NAT traversal is assisted using Interactive Connectivity Establishment (ICE). , the Jingle specification is a Stable Standard, meaning: "'' Implementations are encouraged and the protocol is appropriate for deployment in production systems, but some changes to the protocol are possible before it becomes a Final Standard.''" The libjingle library, used by Google Talk to implement Jingle, has been released to the public under a BSD license. It implements both the current standard protocol and the older, pre-standard version. Clients supporting Jingle * Asterisk PBX * Coccinella. * Conversati ...

Inter-Asterisk EXchange
Inter-Asterisk eXchange (IAX) is a communications protocol native to the Asterisk private branch exchange (PBX) software, and is supported by a few other softswitches, PBX systems, and softphones. It is used for transporting voice over IP telephony sessions between servers and to terminal devices. The original IAX protocol is deprecated and has been superseded by a second version, commonly called IAX2. The IAX2 protocol was published as an informational (non-standards-track) RFC 5456 by discretion of the RFC Editor in February 2010. Basic properties IAX is a binary-encoded voice over Internet protocol (VoIP) that is used for streaming media, but is primarily designed for IP voice calls. IAX uses a single User Datagram Protocol (UDP) data stream and port number, by default 4569, between endpoints for both session signaling and media payloads. This feature provides benefits for traversing network address translators at network boundaries, as it simplifies firewall config ...
