un-registration can be done by user (phone) itself (when sending 
REGISTER with Expires 0) or because of a timeout of previous 
registration. The first one can be caught in config file route block, 
for the second you either write a small module and register for callback 
from usrloc module, or as you said, monitor the database.

There are other options, for example, using pua_usrloc module to send 
PUBLISH requests with online/offline states when there are a 
registration/unregistration (including the timeout) events.

In the devel version (upcoming 3.2.0) you can look also to 
pua/presence_reginfo modules.

Cheers,
Daniel
