OpenSIPS 1.11.3

An open source SIP server implementation
OpenSIPS is an GPL implementation of a multi-functionality SIP Server that targets to deliver a high-level technical solution (performance, security and quality) to be used in professional SIP server platforms. OpenSIPS started as a fork of Fokus Fraunhofer SIP Express Router (SER) project.

OpenSIPS wants to be a more open project, not only from license point of view, but more open as project management, especially for external contributions.

OpenSIPS's goal is to overcome the development latency of current SER project and to ensure a shorter path into a release for new added features.

Main features:

  • robust and performant SIP (RFC3261) Registrar server, Location server, Proxy server and Redirect server
  • small footprint - the binary file is small size, functionality can be stripped/added via modules
  • plug&play module interface - ability to add new extensions, without touching the core, therefore assuring a great stability of core components
  • stateless and transactional statefull SIP Proxy processing
  • support for UDP/TCP/TLS/SCTP transport layers
  • IPv4 and IPv6
  • support for SRV and NAPTR DNS
  • SRV DNS failover
  • IP Blacklists
  • multi-homed (mhomed) and multi-domain support
  • flexible and powerful scripting language for routing logic
  • variables support in script - script variables, pseudo-variables (access to the SIP messages), AVPs (values persistent per SIP transactions)
  • management interface via FIFO file and unix sockets
  • authentication, authorization and accounting (AAA) via database (MySQL, Postgress, text files), RADIUS and DIAMETER
  • digest and IP authentication
  • Presence Agent support (many additional integration features)
  • XCAP support for Presence Agent
  • CPL - Call Processing Language (RFC3880)
  • SNMP - interface to Simple Network Management Protocol
  • management interface (for external integration) via FIFO file, XMLRPC or Datagram (UDP or unixsockets)
  • NAT traversal support for SIP and RTP traffic
  • ENUM support
  • PERL Programming Interface - embed your extensions written in Perl
  • Java SIP Servlet Application Interface - write Java SIP Servlets to extent your VoIP services and integrate with web services
  • load balancing with failover
  • least cost routing
  • support for replication - REGISTER offer new functions for replicating client information (real source and received socket).
  • logging capabilities - can log custom messages including any header or pseudo-variable and parts of SIP message structure.
  • modular architecture - plug-and-play module interface to extend the server's functionality
  • gateway to sms (AT based)
  • multiple database backends - MySQL, PostgreSQL, Oracle, Berkeley, flat files and other database types which have unixodbc drivers
  • straightforward interconnection with PSTN gateways
  • dialog support (call monitoring, call termination from proxy side, call profiling)
  • XMPP gateway-ing ( transparent server-to-server translation)
  • impressive extension repository - over 70 modules are included in OpenSIPS repository
  • Scalability:
  • OpenSIPS can run on embedded systems, with limited resources - the performances can be up to hundreds of call setups per second
  • used a load balancer in stateless mode, OpenSIPS can handle over 5000 call setups per second
  • on systems with 4GB memory, OpenSIPS can serve a population over 300 000 online subscribers
  • system can easily scale by adding more OpenSIPS servers
  • OpenSIPS can be used in geographic distributed VoIP platforms
  • straightforward failover and redundancy

What's New in version 1.6.0
  • new 'statistic classes for network and pkg_mem information: NET class , to provide information about the network sockets and PKMEM class, to provide information about the private memory of each process - see http://lists.opensips.org/pipermail/users/2009-April/004868.html
  • # new mem_dump core parameter for a better control on logging memory info. Former "mem_log" was split in mem_log (only for debug log during mallog/free/realloc ops) and mem_dump (for dumping the mem status at runtime/shutdown). This will help in debugging memory leaks - you can request only the mem dumping without actually getting all the debugs during mem ops.
  • For backward compatibility, setting mem_log will automatically set to the same value the mem_dump.
  • To get distinct setting, do:
