I do the same, but then the call comes in while you are rolling. Illegal to punch in your ID. Then the system keeps calling and calling. CHEZZ.I feel your pain. If not on a load, we wait a few minutes and call the VRU.
2-2 and it'll tell you about the load if you did get it.
We also call the same 2-2 to get rescheduled eta's while enroute.
