sipXecs is an open source enterprise communications system.〔(Enterprise Communications System )〕 It was initially developed as a proprietary voice over IP telephony server in 2003 by Pingtel Corporation in Boston, MA,〔(【引用サイトリンク】title= The Essential Guide to Open-Source VoIP - VoIP News )〕 and later extended with additional collaboration capabilities in the SIPfoundry project. Its core feature is a software implementation of the Session Initiation Protocol (SIP), which makes it an IP based communications system (IP PBX). sipXecs is often compared to other open source telephony and softswitch solutions such as Asterisk,〔(【引用サイトリンク】title= Asterisk NOW vs. sipXecs vs. SwitchVox vs. Trixbox Pro - Comparing User Benefits )〕 FreeSWITCH,〔(【引用サイトリンク】 title= New Version of sipXecs Uses FreeSWITCH for Automated Attendant, Conferencing )〕 and the SIP Express Router, but the design of sipXecs is substantially different from Asterisk and FreeSWITCH. ==History== Development of sipXecs was started in 2003 by Pingtel Corp, a Boston, MA based venture backed company. In 2004, Pingtel adopted an open-source business model and contributed the codebase to the not-for-profit organization SIPfoundry.〔(【引用サイトリンク】title= Pingtel Goes Open Source with IP Telephony Platform )〕 It has been an open source project since then.〔(【引用サイトリンク】title= SIPfoundry on GitHub )〕 Pingtel's assets were acquired by Bluesocket in July 2007.〔(【引用サイトリンク】title= Bluesocket snaps up open source IP PBX maker Pingtel )〕 In August 2008 the Pingtel assets were acquired from Bluesocket by Nortel.〔(【引用サイトリンク】 title= Nortel picks up Pingtel from Bluesocket )〕 Subsequent to the acquisition by Nortel, Nortel released the SCS500〔(【引用サイトリンク】title= First Look: Nortel Ramps Up SCS500 Platform )〕 product based on sipXecs. SCS500 was positioned as an open and software-only telephony server for the SMB market up to 500 users and received some recognition.〔(【引用サイトリンク】title= Asterisk may be older, but sipXecs is better )〕 It was later renamed SCS and positioned as an Enterprise Communications System.〔(【引用サイトリンク】title= Nortel Expands Software Communication System Solution )〕 Subsequent to the Nortel bankruptcy〔(【引用サイトリンク】title= Nortel Networks Files for Chapter 11 )〕 and the acquisition of the Nortel assets by Avaya,〔(【引用サイトリンク】 title= Avaya to Purchase Nortel Unit )〕 Avaya has backed away from SCS in an effort to rationalize its product portfolio post acquisition of Nortel. The sipXecs solution continued to be used as the basis for the (Avaya Live ) cloud based communications service. In April 2010 the founders of SIPfoundry founded eZuce.〔(【引用サイトリンク】title= SIPfoundry Founders Go Commercial with eZuce )〕 eZuce commercialized the sipXecs solution in close cooperation with SIPfoundry and the open source community. sipXecs is typically deployed by enterprises wanting to replace a traditional private branch exchange (PBX) with a software-based solution that can be produced in a cloud environment. In addition to telephony features, sipXecs offers collaboration capabilities such as enterprise instant messaging and conferencing. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SipXecs」の詳細全文を読む スポンサード リンク
