I don't see these with my install of 1.2, probably because I have 
removed notices from logger.conf

I also don't use qualify, and don't have any issues with SIP devices on

Perhaps the simple solution is to remove "notice" from the console line 
in logger.conf. Especially if the SIP devices all work.
