-v Increase the level of verboseness on the console. The more times
-v is specified, the more verbose the output is.
Specifying this option implies -f and will cause asterisk to no
longer fork or detach from the controlling terminal. This
option may also be used in conjunction with -r and -R.
Note: This always sets the verbose level in the asterisk process,
even if it is running in the background. This will affect the
size of your log files.
