 SIP Express Router (SER) is an industrial-strength, free VoIP 
893ade1e
 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, 
c6a041c5
 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 
c6a041c5
 the server code and provide thereby advanced and customized

 services.

 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 iptel.org 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.
