Description

OpenSER 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 * LCR - least cost routing * load balancing * AAA with database (MySQL, Postgres, Unixodbc) or RADIUS backend * audio, video, instant messaging and presence

Options

-h Displays a short usage description, including all available options. -c Checks the config file and displays the aliases and listen interface list. -C Similar to -c but in addition checks the flags of exported functions from included route blocks. -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. -v Turns on via host checking when forwarding replies. -d Turns on debugging, multiple -d increase the debug level. -D Runs openser in the foreground (it doesn't fork into daemon mode). -E Sends all the log messages to stderr. -T Disables TCP support. -V Displays the version number.
-f config-file: Reads the configuration from config-file (default /usr/etc/openser/openser.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 openser will crash, the core file will be generated here.
-W method Specify poll method.
-t chroot-dir: Forces openser to chroot after reading the config file.
-u uid
Changes the user id under which openser runs.
-g gid
Changes the group id under which openser runs.
-P pid-file
Creates a file containing the pid of the main openser process.
-i fifo-path: Creates a fifo, useful for monitoring openser status.
-x socket-path: Creates a unix socket, useful for monitoring openser status ( same as -i fifo-path but using unix sockets instead).
