V. 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.

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.
