Elastix is a unified communications server software that brings together IP PBX, email, IM, faxing and collaboration functionality. It has a Web interface and includes capabilities such as a call center software with predictive dialing.
The Elastix 2.5 functionality is based on open source projects including Asterisk, FreePBX, HylaFAX, Openfire and Postfix. Those packages offer the PBX, fax, instant messaging and email functions, respectively.
As of Elastix 5.0 all functionality is provided through 3CX, a software based private branch exchange (PBX) based on the SIP (Session Initiation Protocol) standard. It enables extensions to make calls via the public switched telephone network (PSTN) or via Voice over Internet Protocol (VoIP) services. Elastix 5.0 is an IP business phone system that supports standard SIP soft/hard phones, VoIP services and traditional PSTN phone lines.
Elastix 2.5 is free software, released under the GNU General Public License. Elastix 5.0 is Proprietary released under the terms of the 3CX license.
Elastix 2.5 has a good support for telephony hardware. [2] It includes drivers for the major manufacturers like Dinstar, OpenVox, Digium, Khomp, Sangoma Technologies Corporation, Rhino Equipment, Xorcom, and Yealink . [3] The most of these drivers are supported through the zaptel project or modified versions of it. Other drivers are supported by the mISDN project and other projects.
Elastix 2.5 also supports other phone brands thanks to the SIP and IAX protocols that Asterisk implements. These protocols are based on public available standards. For this reason any manufacturer can build a product that supports them. Some certified manufacturers are Ascom, Snom and Yealink.
Elastix 2.5 was the first distribution that included a call center module with a predictive dialer, released entirely as free software. This module can be installed from the same web-based Elastix interface through a module loader. The call center module can handle incoming and outgoing campaigns. It can also optionally be made more powerful by adding common third party modules like QueueMetrics [4] and WombatDialer. [5]
Elastix was created and maintained by PaloSanto Solutions, an Open Source support company based in Ecuador. Elastix was released to the public for the first time in March 2006. It was not a complete distribution but a Web interface for CDR (Call Detail Records) reporting. It was not until late December 2006 that Elastix was released as a Linux distribution with Asterisk, Zaptel and a number of other packages which were easily administrated via a user friendly Web interface that caught the community's attention.
The Elastix 2.5 Linux distribution is based on CentOS, which has binary compatibility with Red Hat Enterprise Linux.
From its initial release until now the Elastix distro has grown in popularity. The project was nominated for two straight years (2007 and 2008) as finalist in the SourceForge Community Choice Awards. [6] [7]
In 2016 the Elastix project was acquired by 3CX. With this acquisition the Elastix Distro versioned at 5.0 was switched to a proprietary software on top of Debian with the 3CX platform. [8] [9] Open-source forks of pre-version 5 Elastix are being maintained by the Issabel project.
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.
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.
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).
Digium, Inc. is a communications technology company based in Huntsville, Alabama, and since 2018, a subsidiary of Sangoma Technologies Corporation. The company makes VoIP business phone systems, IP phones, and hardware products. It was founded in 1999 by Mark Spencer.
Direct inward dialing (DID), also called direct dial-in (DDI) in Europe and Oceania, is a telecommunication service offered by telephone companies to subscribers who operate private branch exchange (PBX) systems. The feature provides service for multiple telephone numbers over one or more analog or digital physical circuits to the PBX, and transmits the dialed telephone number to the PBX so that a PBX extension is directly accessible for an outside caller, possibly by-passing an auto-attendant.
Skype for Business Server is real-time communications server software that provides the infrastructure for enterprise instant messaging, presence, VoIP, ad hoc and structured conferences and PSTN connectivity through a third-party gateway or SIP trunk. These features are available within an organization, between organizations and with external users on the public internet or standard phones.
A VoIP phone or IP phone uses voice over IP technologies for placing and transmitting telephone calls over an IP network, such as the Internet. This is in contrast to a standard phone which uses the traditional public switched telephone network (PSTN).
SipXecs is a free software enterprise communications system. It was initially developed by Pingtel Corporation in 2003 as a voice over IP telephony server located in Boston, MA. The server was later extended with additional collaboration capabilities as part of the SIPfoundry project. Since its extension, sipXecs now acts as a software implementation of the Session Initiation Protocol (SIP), making it a full IP-based communications system.
This is a comparison of voice over IP (VoIP) software used to conduct telephone-like voice conversations across Internet Protocol (IP) based networks. For residential markets, voice over IP phone service is often cheaper than traditional public switched telephone network (PSTN) service and can remove geographic restrictions to telephone numbers, e.g., have a PSTN phone number in a New York area code ring in Tokyo.
Mobile VoIP or simply mVoIP is an extension of mobility to a voice over IP network. Two types of communication are generally supported: cordless telephones using DECT or PCS protocols for short range or campus communications where all base stations are linked into the same LAN, and wider area communications using 3G or 4G protocols.
FreePBX is a web-based open-source graphical user interface (GUI) that manages Asterisk, a voice over IP and telephony server.
Snom Technology GmbH is a German company which manufactures Voice over Internet Protocol (VoIP) telephones, based on the IETF standard Session Initiation Protocol (SIP). Snom's products are targeted at the small- to medium-sized business sector, home offices, Internet service providers, carriers, and original equipment manufacturers. The company, founded in 1996 and headquartered in Berlin, is a wholly owned subsidiary of VTech Holdings Limited, since 2016.
trixbox was a software PBX based on Asterisk.
An IP PBX 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.
Issabel is open-source Unified Communications PBX software, providing user-friendly web-based configuration, management, and reporting for telephony. Modules providing predictive dialing can be added. It is a fork of the open-source versions of Elastix, developed by the user/developer community when 3CX acquired Elastix, closed the community, halted distribution and development of the open-source versions, and released a proprietary version.
Sangoma Technologies Corporation (Sangoma) is a Canadian company that provides Communications as a Service (“CaaS”) products for businesses. It was founded in 1984. It is publicly traded on the Toronto Stock Exchange.
