test#1
asterisk.conf verbose=0
logger.conf
  verbose defined for console and full,
  no integer level set (should be default of 3 according to logger.conf)
observations:  
  "core show settings" shows 0 verbosity
  VERBOSE messages on console: no
  VERBOSE messages in full: yes

test#2
asterisk.conf verbose=0
logger.conf
  verbose defined for console and full,
  integer level set to 3
observations: 
  "core show settings" shows 0 verbosity
  VERBOSE messages on console: no
  VERBOSE messages in full: yes

test#3
asterisk.conf verbose=3
logger.conf
  verbose defined for console and full,
  no integer level set (should be default of 3 according to logger.conf)
observations: 
  "core show settings" shows 3 verbosity
  VERBOSE messages on console: yes
  VERBOSE messages in full: yes

test#4
asterisk.conf verbose=0
logger.conf
  verbose defined for console and full,
  no integer level set (should be default of 3 according to logger.conf)

connected to remote console and ran 'core set verbose 5'

observations: 
  "core show settings" shows 0 verbosity
  VERBOSE messages on console: yes
  VERBOSE messages in full: yes





'core show settings' the verbosity displayed from this command appears to only be affected by the setting in asterisk.conf

'core set verbose <integer>' sets the verbosity for the remote console you are on

defining VERBOSE in logger.conf for a file like "full" does result in at least VERBOSE level 3 messages being written to the full log

defining VERBOSE in logger.conf for the "console" only results in a level of 0 for any remote console

defining VERBOSE with an integer level in logger.conf for the "console" results in a level of 0 for any remote console

definine VERBOSE with an integer level in asterisk.conf results in a default verbosity of that same level on any remote console

the logger.conf documentation is ambiguous regarding the integer level and whether the special console filename is affected or not "; Verbose takes an additional argument, in the form of an integer level.; Messages with higher levels will be ignored.  If verbose is specified at; all, it will default to 3."




** the v options or d options with the asterisk binary are overridden by asterisk.conf on asterisk load.
