$Id$ SIP Express Router (ser) I. About SIP Express Router (ser) II. Feature List III. About IV. Obtaining Help V. Contact, Licencing and More Information SIP Express Router (SER) is an industrial-strength, free VoIP server based on the session initiation protocol (SIP RFC2543-bis). It is engineered to power IP telephony infrastructures up to large scale. The server keeps track of users, sets up VoIP sessions, relays instant messages and creates space for new plug-in applications. Its proven interoperability guarantees seamless integration with components from other vendors, eliminating the risk of a single-vendor trap. It has successfully participated in various interoperability tests in which it worked with the products of other leading SIP vendors. The SIP Express Router enables a flexible plug-in model for new applications: Third parties can easily link their plug-ins with the server code and provide thereby advanced and customized services. In this way, plug-ins such as SNMP support, RADIUS accounting, or SMS gateway have already been developed and are provided as advanced features. Other modules are underway: Presence server, firewall control, and more. Its performance and robustness allows it to serve millions of users and accommodate needs of very large operators. With a $3000 dual-CPU, the SIP Express Router is able to power IP telephony services in an area as large as the Bay Area during peak hours. Even on an IPAQ PDA, the server withstands 150 calls per second (CPS)! The server has been powering our free SIP site withstanding heavy daily load that is further increasing with the popularity of Microsoft's Messenger. The SIP Express Router is extremely configurable to allow the creation of various routing and admission policies as well as setting up new and customized services. Its configurability allows it to serve many roles: network security barrier, application server, or PSTN gateway guard for example. II. Feature List Based on the latest standards, the SIP Express Router (SER) includes support for registrar, proxy and redirect mode. Further it acts as an application server with support for CPL, instant messaging and presence (IM&P) including a 2G/SMS gateway, a call control policy language, call number translation, private dial plans and accounting, authorization and authentication (AAA) services. SER runs on Sun/ Solaris, PC/Linux, IPAQ/Linux platforms and supports both IPv4 and IPv6. Most of SER features are implemented as plug-in modules. See README-MODULES for a description of modules available in ser distribution. III. About is a know-how organization spun off from Germany's national research company FhG Fokus. One of the first SIP implementations ever, low-QoS enhancements, interoperability tests and VoIP-capable firewall control concepts are examples of well-known FhG's work. continues to keep this know-how leadership in SIP. The access rate of the company's site, a well-known source of technological information, is a best proof of interest. Thousands of hits come every day from the whole Internet. IV. Obtaining Help We offer best-effort free support for ser. "best-effort" means that we try to solve your problems via email as soon as we can, subject to available manpower. If you need commercial support, contact To receive feedback to your inquiries, we recommend you to subscribe to the serusers mailing list and post your queries there. This mailing list is set up for mutual help by the community of ser users and developers. To participate in the mailing list, subscribe at the following web address: Send your questions to If you are concerned about your privacy and do not wish your queries to be posted and archived publicly, you may post to E-mails to this address are only forwarded to's ser development team. However, as the team is quite busy you should not be surprised to get replies with considerable delay. V. Contact, Licensing and More Information For any additional information, send an inquiry to Licensing conditions other than GPL are available on request.
