Whatever you want it to be. A "default/example" config has 
$avp(oexten) = $rU;
in the LOCATION route just before the lookup (which overwrites $rU on a

In whatever way works for you. Add a diversion header or some custom
header.

Yes, t_set_fr() lets you do that per transaction.

Store the user timeout in for example urs_preferences and query it using
sqlops/avpops
