Actually if you read the log entry, it can easily be interpreted that 
way.  Log entries really are a delicate balancing act - you need to 
provide enough information to determine what the problem is without 
becoming too wordy.  The only real way I could see to improve that log 
entry would be to say "Received SIP subscribe for peer without 
*configured* mailbox: 9163"  The log correctly identifies it as a 
"notice" since it's not an error condition.  Any log entry longer than 
this would bloat log files even further than they already are - and 
Asterisk log files on even a moderately busy system are already about as 
easy to follow as your average plate of spaghetti.
