New in Core

Interpreter

Parameters

  • verbose_startup - control if printing routing tree and udp probing buffer debug messages should be printed at startup

Functions

Misc

  • support for parsing the Call-Info header
  • do not terminate on harmless SIGCHLD (e.g., when kemi python scripts create and terminate new processes)
  • added function to return route block name from crt action
  • compile with system malloc for pkg if MEMPKG=sys
  • if MEMDBGSYS=1, the use a debug variant for system malloc
  • support for base58 encoding and decoding
  • mem - new functions for pkg/shm - mallocxz() and reallocxf()
    • pkg_mallocxz(size) / shm_mallocxz(size) - same as the corresponding malloc function, but the allocated buffer is filled with 0. It is equivalent of { p=malloc(size); if(p) memset(p, 0, size); }
    • pkg_reallocxf(p, size)/shm_reallocxf(p, size) - same as the corresponding realloc functions, but the old pointer is always freed, even if the realloc operation fails. The BSDs have reallocf()
  • added rpc command core.ppdefines - list preprocessor defines enabled in config
  • tcp - new flag F_CONN_NOSEND (mark connection for no-send data)
    • if flag set, the data is not sent over the connection
    • can be set by drop() inside event_route[tls:connection-out]
  • added rpc command core.modules - list the names of loaded modules

kamailio.cfg

  • filter out sip scanner even when anti-flood is not enabled
  • handle retransmissions also for requests within dialogs

Tools

kamcmd

kamctl

  • added srv command
    • shortcuts to RPC commands to print sockets, aliases and available RPC commands
  • added db subcommand to mange records in version table

kamcli
