       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).
