NAME
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
shared_mem_size ] [ -w working-dir ] [ -W method ] [ -t chroot-dir ] [

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
process.
-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).
