asterisk users - Dec 2014 - Asterisk 11.13 - No verbose logs

Hi all,

On an Elastix server with asterisk 11.13.0 I have no verbose logs 
despite the fact that it's OK in CLI, eg verbose set to 3 in my case

Logger.conf

[logfiles]
;
; Format is "filename" and then "levels" of debugging to be
included:
;    debug
;    notice
;    warning
;    error
;    verbose
;
; Special filename "console" represents the system console
;
;debug => debug
; The DTMF log is very handy if you have issues with IVR's
;dtmf => dtmf
;console => notice,warning,error
;console => notice,warning,error,debug\
;messages => notice,warning,error
full => notice,warning,error,debug,verbose
verbose => verbose

Files verbose and full in /var/lib/asterisk contains only:

[Dec  3 12:47:55] Asterisk 11.13.0 built by palosanto @ 
rpmbuild32-2.elastix.palosanto.com on a i686 running Linux on 2014-10-02 
17:41:51 UTC

Files are owned by user/group asterisk, rw r mode. I tried to rotate 
logs, no changes. Disk is not full, fuul log file contains others infos.

Any clue?
