Some of the features that OpenSIPS brings

• 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
