SIP Express Router (kamailio)
SIP proxy and registrar

  • " November 04, 2008 - SER joins the sip-router project "
  • " First is important to clarify: from version 3.0.0 on, Kamailio and SER are identical in terms of source code. "

SER or SIP Express Router is a very fast and flexible SIP (RFC3621) server. It handles thousands of calls per second on low-budget hadware. A C shell-like scripting language provides full control over the server's behaviour. Its modular architecture lets users load only the required functionality. The following modules are available: digest authentication, CPL scripts, instant messaging, MySQL support, a presence agent, Radius authentication, record routing, an SMS gateway, a Jabber gateway, a transaction module, a registrar, and user location.
