Hi john,

Using the dialog module should do the trick. When the dialog is setup, 
use an AVP to set the dialog timeout (see the timeout_avp at 
http://www.opensips.org/html/docs/modules/1.5.x/dialog.html#timeout-avp-id) 
to force dialog termination after certain time  and also enable BYE 
sending at dialog termination ( see bye_on_timeout_flag at 
http://www.opensips.org/html/docs/modules/1.5.x/dialog.html#bye-on-timeout-flag-id).

Regards,
Bogdan
