Hi Paul,

Right now there is no way for an external application to find out when a 
registration do timeout....Well there is a really ugly hack -> use DB 
support for usrloc (preferable db_mode WRITE_THROUGH) and install in DB 
usrloc table a trigger on DELETE query -> this will be triggered each 
time opensips removes a contact. On trigger, you can push some info 
about the removed contact in a different table which is monitored by 
your external app...Again this is really ugly.

Anyhow, we have in plan to add in OpenSIPS an Event Interface (we will 
soon publish the description) that will offer you an elegant and 
efficient solution for this case.
