• 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)
• All standard modules have been reviewed and made IPv6 compliant where it was the case

SIP SIMPLE Presence Services

• New module to provide MSRP relay function
• 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

Call Stateful Proxy

• Ability to send OPTIONS keepalive requests to detect if the ongoing calls are still active
• New event routes to handle specific call state events such as START, END or FAILED

• 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
