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).

       FILES  kamailio
              /etc/kamailio/kamailio.cfg
              /usr/lib/x86_64-linux-gnu/kamailio/modules/*
