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 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.
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 iptel.org
iptel.org 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.
iptel.org 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 [email protected].
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.

If you are concerned about your privacy and do not wish your queries
to be posted and archived publicly, you may post to
[email protected].
E-mails to this address are only forwarded to iptel.org's ser development
team. However, as the team is quite busy you should not be surprised to
get replies with considerable delay.
