opensips — flexible and roboust SIP (RFC3261, RFC3263) server for Voice over IP (VoIP)
opensips [ -hcCrRvdDEVT ] [ -f config-file ] [ -l address ] [ -n processes-no ] [ -N tcp processes-no ] [ -b max_rcv_buf_size ] [ -m shared_mem_size ] [ -w working-dir ] [ -W method ] [ -t chroot-dir ] [ -u uid ] [ -g gid ] [ -P pid-file ] [ -i fifo-path ] [ -x socket-path ]
OpenSIPS is a SIP-based VoIP server running on most Unix-like operating systems. It supports UDP, TCP and TLS transport layers. Among its features:
SIP Proxy Server, SIP Registrar Server, SIP Redirect Server, SIP Location Server, SIP Application Server
Call Processing Language (RFC3880)
server side NAT traversal
AAA with database (MySQL, Postgres, Unixodbc) or RADIUS backend
audio, video, instant messaging and pressence
Displays a short usage description, including all available options.
Checks the config file and displays the aliases and listen interface list.
Similar to -c but in addition checks the flags of exported functions from included route blocks.
Uses dns to check if it is necessary to add a "received=" field to a via.
Same as -r but uses reverse dns.
Turns on via host checking when forwarding replies.
Turns on debugging, multiple -d increase the debug level.
Runs opensips in the foreground (it doesn't fork into daemon mode).
Sends all the log messages to stderr.
Disables TCP support.
Displays the version number.
- -f config-file
Reads the configuration from config-file (default /usr/etc/opensips/opensips.cfg ).
- -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.
- -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 ).
- -b max_rcv_buf_size
Maximum receive buffer size which will not be exceeded by the auto-probing procedure even if the OS allows.
- -m shared_mem_size
Size of the shared memory which will be allocated (in Megabytes).
- -w working-dir
Specifies the working directory. In the very improbable event that opensips will crash, the core file will be generated here.
- -W method
Specify poll method.
- -t chroot-dir
Forces opensips to chroot after reading the config file.
- -u uid
Changes the user id under which opensips runs.
- -g gid
Changes the group id under which opensips runs.
- -P pid-file
Creates a file containing the pid of the main opensips process.
- -i fifo-path
Creates a fifo, useful for monitoring opensips status.
- -x socket-path
Creates a unix socket, useful for monitoring opensips status ( same as -i fifo-path but using instead unix sockets).
