openser - flexible and roboust SIP (RFC3261, RFC3263) server for Voice
over IP (VoIP)
SYNOPSIS
openser [ -hcCrRvdDEVT ] [ -f config-file ] [ -l address ] [ -n processes-no ] [ -N tcp processes-no ] [ -b max_rcv_buf_size ] [ -m

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 pressence
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 /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 pro
- cess.
- -i fifo-path
- Creates a fifo, usefull for monitoring openser status.
- -x socket-path
- Creates a unix socket, usefull for monitoring openser status ( same as -i fifo-path but using instead unix sockets).
