Openser is a very fast and flexible sip (rfc3261) proxy server. written entirely in c, openser can handle thousands calls per second even on low-budget hardware.

c shell-like scripting language provides full control over the server's behaviour. its modular architecture allows only required functionality to be loaded.

among others, the following modules are available: digest authentication, cpl scripts, instant messaging, mysql support, presence agent, radius authentication, record routing, sms gateway, jabber/xmpp gateway, transaction module, registrar and user location, xml-rpc interface.

this package contains the main openser binary along with the principal modules and support binaries.
