OpenSER is a SIP-based VoIP server running on most Unix-like operating
systems. It supports UDP, TCP and TLS transport layers. Among its
* 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
-h Displays a short usage description, including all available
-c Checks the config file and displays the aliases and listen
-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
-E Sends all the log messages to stderr.
-T Disables TCP support.
-V Displays the version number.
Reads the configuration from config-file (default
-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.
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 ).
Maximum receive buffer size which will not be exceeded by
the auto-probing procedure even if the OS allows.
Size of the shared memory which will be allocated (in
Specifies the working directory. In the very improbable
event that openser will crash, the core file will be
-W method Specify poll method.
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
Creates a fifo, usefull for monitoring openser status.
Creates a unix socket, usefull for monitoring openser
status ( same as -i fifo-path but using instead unix
