Usage

Overview

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.

-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/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).
