  • Enhancements and new features in over 50 existing modules
  • New internal libraries and functionalities in the core

Scalability

  • Generic database clustering module – ability to perform database operations across different servers and types of database, using policies such as round robin, serial try or parallel write
  • Cassandra database connector
  • Fine control of worker processes per network socket
  • Easy mode to advertise public address per socket, making installations in the cloud and virtual systems straightforward (e.g., on Amazon EC2)
  • Handle Redis array replies and auto-reconnect to servers
  • New dedicated mili-second timers used for various tasks to avoid interfering with SIP retransmissions
  • Support for handling GRUU and SIP Outbound
  • Config function for sending data over distributed message queue (dmq module)

IPv6

  • All IPv6 network interfaces are auto-detected and Kamailio start listening on them (if no strict listening rules are set)

  • New module for managing UA configuration via SIMPLE extensions
  • RFC 4827 (presence hard-state) support
  • Dedicated pool of notifier processes to cope better with large number of subscriptions
  • Added support for DB only mode to several memory structures, very useful for scaling Presence and Resource List Services across multiple servers
  • Option to store records in different database servers
  • Performance improvements to embedded XCAP server, presence server, presence user agent and resource lists modules

  • New module for time based routing using iCal or Perl-like time recurrence matching rules
  • Embedded JSON library for serialization of data structures
  • Support for handling URN
  • Fast matching operation in configuration file and dialplan module
  • Internal unique ID generator across a farm of SIP servers
  • Ability to run RPC control commands via HTTP using the embedded HTTP server
  • Option to enable memory chunks merging, to avoid fragmentation
  • HEPv2 support for siptrace and sipcature extensions
  • Execute route blocks on micro-second timer base
  • New transformations for string and line-based processing
  • All RPC control commands can be executed via MI
  • More options for local memory caching behaviour (htable module)
  • Option to add extra headers to locally stored text messages

Security

  • Ability to set upper limit for TLS connections
  • Print detailed information about active TLS connections
