SIP Express Router (SER) is a SIP server licensed under the GNU General Public License. It can be configured to act as SIP registrar, proxy or redirect server. SER features presence support, RADIUS/syslog accounting and authorization, XML-RPC-based remote control and others. Web-based user provisioning, serweb, is available. SER's performance allows it to deal with operational burdens, such as broken network components, attacks, power-up reboots and a rapidly growing user population. SER can be configured for many scenarios including small-office use, enterprise PBX replacements and carrier services. ==History== SER was initially developed by Fraunhofer in 2001. Part of the Fokus team then moved, with the SER copyrights, to the newly created company iptel.org in 2004. Two of the five SER core developers and one main contributor started a new free and open source software project named OpenSER. Additional free and open source code was contributed by independent third parties. SER and OpenSER followed different development paths. SER 2.0 Release Candidate 1 (Ottendorf) was made available May 12, 2007 and is currently undergoing heavy development. The SER project remains free and open source. In 2005, the company IPtel.org was bought by TEKELEC, and is responsible for the TEKELEC session router and CSCF. In 2008, OpenSER was renamed Kamailio to avoid conflict with similar trademarks. From the OpenSER/Kamailio site, "Kamailio is a hawaiian word. Kama'ilio means talk, to converse. It was chosen for its special flavour." In November 2008 the Kamailio developers announced to team up in the future with the SER developers to create the sip-router project. 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「SIP Express Router」の詳細全文を読む スポンサード リンク
