### Description

When event_route[usrloc:contact-expired] is triggered, the pseudo-var $ulc(exp=>aor) contains only the userpart of the aor of the expired registration

### Troubleshooting

``` modparam("usrloc", "use_domain", 1) [...] event_route[usrloc:contact-expired] { xlog("L_NOTICE", "Contact ruid $ulc(exp=>ruid) to $ulc(exp=>addr) for user $ulc(exp=>aor) expired\n"); } ```
