       yate - launch the YATE telephony engine


       yate [options] [commands]


       yate  is a telephony engine that supports client, PBX and IVR functions
       trough plugins.


       -h, --help
              Display a short help message and exit

       -V, --version
              Display program version and exit

       -v     Verbose debugging (you can use more than once)

       -q     Quieter debugging (you can use more than once)

       -d     Daemonify, suppress output unless logged

       -s     Supervised, restart if crashes or locks up

       -r     Enable rotation of log file (needs -s and -l)

       -l filename
              Log to file - should be used whenever running in daemon mode

       -p filename
              Write PID of the supervisor or primary thread to file

       -n configname
              Use specified configuration name, overrides default "yate"

       -c pathname
              Path to conf files directory, overrides compiled-in value

       -u pathname
              Path to user data files directory, overrides compiled-in value

       -m pathname
              Path to modules directory, overrides compiled-in value

       -e pathname
              Path to shared directory, overrides compiled-in value

       -x relpath
              Relative path to extra modules directory (can be repeated)

       -w directory
              Change working directory

       -N nodename
              Set the name of the node in a cluster

   Debugging options (may not be compiled in)
       -C     Enable core dumps if supported by the operating system

       -F     Increase the maximum file handle to compiled value

       -t     Truncate the log file instead of appending to it

              Special debugging options

       -Da    Abort (coredumps if allowed) if bugs are encountered

       -Dm    Attempt to debug mutex deadlocks by setting a maximum 10s limit,
              if repeated halves the limit

       -Dl    Attempt  to  load  modules without having their symbols globally

       -Dc    Call dlclose() until it gets an error

       -Du    Do not unload modules, just try to call thier finalization code

       -Di    Reinitialize after first initialization

       -Dx    Exit immediately after initialization

       -Dw    Delay for one second the creation of the first worker thread

       -Do    Colorize the output using ANSI control character sequences

       -Ds    Abort if bugs are encountered even during shutdown

       -Dt    Add start time relative timestamps to debugging messages

       -De    Add EPOCH (1-1-1970 GMT) based timestamps to debugging messages

       -Df    Add   GMT   timestamps   to   debugging   messages   in   format


       Each   command   is   sent   to  the  YATE  modules  immediately  after
       initialization.  Modules define command syntax so that is not described
       here. Please look at the documentation for each module.


       - SIGTERM and SIGINT (Ctrl-C) will cleanly stop the engine

       - SIGQUIT (Ctrl-\) will reinitialize the modules

       - SIGHUP will reinitialize the modules if started in daemon mode (-d)

       - SIGUSR1 will initiate a gracefull restart (when no plugin is busy)

       - SIGUSR2 will initiate an immediate restart


       Under various *BSD implementations the dlclose() function is broken and
       may generate a segfault on exit.

       Some libpthread implementations are broken and may fail  to  start  the
       threads or fail to cleanup when the thread terminates.
