 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 

-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.
