cfgutils

  • new functions
    • route_if_exists() calls a routing block only if it exists in the configuration script
    • check_route_exists() checks if a routing block exists in the script.

db_mysql

db_postgres

  • handle prepare statements in DB APIv2

debugger

  • new parametes:
    • per module debug level
    • log_assign. Enables the log of every single assign action on config
    • reset_msgid. Enables the ability to reset the msgid ( $mi ) through the RPC command.
  • new functions:
    • dbg_pv_dump() dumps the pv_cache content in json format.
  • new RPC commands:
    • options to enable/disable per module log level as well as set per module log level at runtime.
    • dbg.reset_msg: resets the msgid ( $mi ).

htable

  • new htable.sets and htable.seti RPC commands
  • cross-server replication via DMQ module integration

nathelper

  • new option - natping_disable_bflag can be set on a per-registration basis to disable NAT pings completely

outbound

  • flow-token key is now automatically generated

permissions

* DNS domain names in address table - possibility to check also against DNS domain names with allow_address() function.Now in the address table one group can have exact IPs, subnet IPs and DNS domain names

presence

  • RPC command presence.cleanup

pv

  • RPC commands shvGet and shvSet to manipulate and list shared variables

registrar

  • add Supported headers for outbound extensions in replies
  • RFC 5626 section 6 support - behaviour when outbound in use but first edge proxy does not support it
  • added additional unregister() exported function to allow the removal of a specific contact - contact is removed by using the ruid (unique ID for the location record)
  • set_q_override API function - override the value of the q parameter from the Contact header in subsequent calls to the save() function for the current request

rr

  • use sips to build RR headers if R-URI has sips

rtpproxy

  • database support to rtpproxy
    • if db_url modparam is set rtpproxy sets will be loaded from database
    • if the instance is marked as disabled in database it will be loaded as disabled

sca

  • private hold handling

sdpops

  • new functions:
    • sdp_with_transport(string). Checks if is a media with the transport string.
    • sdp_remove_transport(string). Removes the media info from the SDP that matches string transport.

siputils

  • new functions:
    • is_supported(option) that can be used to check if request has a Supported header listing the given option.

snmpstats

  • the SNMPstats module has been extended with a large set of new data, and the KAMAILIO-MIB has been extended with new OIDs
  • the new data reflects the Kamailio server process (memory, configuration at compile time), network transports and modules.

tm

  • new event route to be executed for each branch failure - branch_failure_route
  • asynchronous processing of SIP responses in configuration file

usrloc

  • new RPC commands:
    • ul.rm
    • ul.rm_contact
    • ul.flush
    • ul.add
  • ul.add RPC and ul_add MI commands modified to be able to set the contact path
  • new option for db_mode - DB_READONLY (4)
    • location records are loaded only at startup
    • no write back to database, not even at shutdown
    • useful when registrations are replicated to another node that does the db storage at runtime

New in Core

  • IPv6 compile time flag removed - it is not possible to compile Kamailio without IPv6 anymore, improving the code maintainability in the core and several modules
  • set TOS for IPv6 sctp sockets
  • the syn_branch parameter has been removed from the core, as Kamailio was not fully standard compliant if this was activated.
  • auto-define cfg directive MOD_modname for each loaded module
    • example: if acc module is loaded, MOD_acc is defined in cfg

Components

  • SCTP support implementation from core was moved as a module. No need to recompile everything to get SCTP support, just load sctp module
  • STUN implementation from core was moved as a module

Tools

kamctl

  • added parameters to add the contact path: kamctl ul add <user> <uri> <expires> <path>
  • command for dialog module management

kamdbctl

  • new command 'add-tables <gid>' to create only specific table grouped under same <gid> name
