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 /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:]address[:port], where proto = udp|tcp and address = host|ip_address|interface_name. Example: -l localhost, -l udp:127.0.0.1:5080, -l eth0:5062. The default behaviour is to listen on all the ipv4 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/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).
