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)
- ENUM support
- server side NAT traversal
- load balancing
- 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).
