It might be worth running something like iostat on your box to see if you see a spike in iowait as voicemail is being checked. We resolved it simply by rate limiting our rsync jobs. In your case with a busy database, you might want to look at your MySQL indexes and/or cache settings - this might be something worth asking about on the respective MySQL discussion groups as well as here.

you could also throw in some more stuff like the following and run it 
for 24 hours every second, then check the log for the timestamp to 
figure out what happened:

while true; do echo `date`; asterisk -rx 'sip show peers'; asterisk -rx 
'sip show channelstats'; mysqladmin --password=yourpass processlist; ps 
auxww; vmstat; iostat; echo; echo; echo; sleep 1; done >> log.txt
