Given the time constraints around organ donation and transplantation, this seems reasonable. If you only have a couple of hours before the organ is no longer viable you can't reasonably sit around hoping someone will return your call. Ideally, you should be alerted that your position on the waitlist is approaching so that you know to answer any incoming calls in case it's "the one". I have no idea if this reflects reality however.
