Correct, not phone available until midnight.

Long call to a DH or to operate is 13 hours, but long call to FSB is 12 hours and FSB callout to a DH is 30 minutes, so they could legally assign you to a DH in 12+30, it would just take two steps to do it.

Not sure why long call didn't go by show time of 12 hours, similar to short call show time is 2+30, then add 30 for DH and 60 to operate.
