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 receive buffer size which will not be exceeded by the auto-probing procedure even  if
                   the 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/x86_64-linux-
                   gnu/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).
