DESCRIPTION

kamailio is a very fast and configurable SIP (RFC3261) server.

OPTIONS

-a auto-aliases-mode: Enable auto-aliases with 'yes' or 'on', disable with 'no' or 'off
--alias=val: Add an alias, the value has to be '[proto:]hostname[:port]' (like for 'alias' global parameter)
--atexit=val: Control atexit callbacks execution from external libraries which may access destroyed shm memory causing crash on shutdown. Can be y[es] or 1 to enable atexit callbacks, n[o] or 0 to disable, default is yes.
-A pre-processor-define: Add config pre-processor define (e.g., -A WITH_AUTH, -A N=1, -A X='"Y"')
-b max_rcv_buf_size: Maximum OS UDP receive buffer size which will not be exceeded by auto-probing-and-increase procedure even if OS allows.
-B max_snd_buf_size: Maximum OS UDP send buffer size which will not be exceeded by auto-probing-and-increase procedure even if OS allows.
-c: Checks the config file and displays the aliases and listen interface list.
--cfg-print: Print configuration file evaluating includes and ifdefs
-d: Turns on debugging, multiple -d increase the debug level.
--debug=val: Debugging level value
-D: Control how daemonize is done:
-D - do not fork (almost) anyway (run in foreground, doesn't fork into daemon mode);
-DD - do not daemonize creator (main process is not daemonized);
-DDD - daemonize (default)
-e: Log messages printed in terminal colors (requires -E)
-E: Sends all the log messages to stderr.
-f config-file: Reads the configuration from config-file (default /usr/local/etc/kamailio/kamailio.cfg ).
-g gid: Changes the group id under which kamailio runs.
-G pgid-file: Creates a file containing the pgid of the main kamailio process.
-h --help: Displays a short usage description, including all available options.
-I: Displays details of internal constants and attributes.
-K: Turns on via host checking when forwarding replies.
-l address: Listens on the specified address/interface. Multiple -l mean listening on multiple addresses. The address format is [proto:]addr_lst[:port][/advaddr][/socket_name], where proto=udp|tcp|tls|sctp, addr_list = addr|(addr, addrress), addr=host|ip_address|interface_name, advaddr=addr[:port] (advertised address) and socket_name=identifying name. E.g: -l localhost, -l udp:127.0.0.1:5080, -l eth0:5062, -l udp:127.0.0.1:5080/1.2.3.4:5060, -l udp:127.0.0.1:5080//local, -l udp:127.0.0.1:5080/1.2.3.4:5060/local, -l The default behaviour is to listen on all the interfaces.
--loadmodule=name: load the module specified by name
--log-engine=name: log engine name and data
-L modules-dir: Specifies the directory where to look for kamailio modules (default: /usr/local/lib/kamailio/modules or /usr/lib64/kamailio/modules)
-m shared_mem_size: Size of the shared memory which will be allocated (in Megabytes).
--modparam=modname:paramname:type:value: set the module parameter type has to be 's' for string value and 'i' for int value, example: --modparam=corex:alias_subdomains:s:" NAME ".org
-M private_mem_size: Size of the private memory which will be allocated per process (in Megabytes).
-n processes-no: Specifies the number of children processes forked per interface (default 8).
-N tcp processes-no: Specifies the number of children processes forked to handle tcp incoming connections (by default is equal to -n ).
-O optimization-level: Script optimization level (debugging option).
-P pid-file: Creates a file containing the pid of the main kamailio process.
-Q: Number of sctp child processes (default: equal to -n ).
-r: Uses dns to check if it is necessary to add a "received=" field to a via.
-R: Same as -r but uses reverse dns (to use both: -rR ).
--server-id=num: Set the value for server_id
--subst=exp: Set a subst preprocessor directive
--substdef=exp: Set a substdef preprocessor directive
--substdefs=exp: Set a substdefs preprocessor directive.
-S: Disables SCTP support.
-t chroot-dir: Forces kamailio to chroot after reading the config file.
-T: Disables TCP support.
-u uid: Changes the user id under which kamailio runs.
-v -V --version: Displays the version number.
-x name: Specify internal manager for shared memory (shm) can be: fm, qm or tlsf
-X name: Specify internal manager for private memory (pkg) if omitted, the one for shm is used
-Y dir: Runtime dir path
-w working-dir: Specifies the working directory. In the very improbable event that kamailio will crash, the core file will be generated here.
-W type: poll method (depending on support in OS, it can be: poll, epoll_lt, epoll_et, sigio_rt, select, kqueue, /dev/poll).
