IA robocalls don't know your future schedule, I get IA calls all the time for trips that would be with conflict.

While on the topic of robocalls... I was on rotation yesterday with a 0500 report for a 0600 push and got a robocall at 0400 telling me I had been rerouted. The reroute didn't change the route at all, just my 1st leg was a DH on the exact same flight I'd originally been scheduled to fly. I was on a 30 hour layover so there was plenty of "opportunity" to get 8 hours sleep; however, the robocall was 30 minutes prior to my planned alarm and it woke me up. Other than having a heart attack that I'd overslept pickup I wasn't much the worse for wear; however, could it have been interpreted as interrupting my opportunity for 8 hours sleep?

edit: and for the haters -- no I don't pick up my phone on rotation, but even on vibrate my phone will sometimes wake me up. When you see CS on the caller ID screen it gets your attention when you don't think they should have any reason to be calling you .
