Notification of Assignment
a. The Company shall notify a Reserve Pilot of a Pairing assignment via
JETCRW at the time the Pairing is placed on the Pilot’s schedule. For Pairing assignments made after the DRO has been published, if a Pilot has not acknowledged the assignment at the applicable Reserve callout time,
the Company shall establish Positive Contact.

I think the positive contact “attempt” only comes into play if you don’t answer your phone, like it is today. That being said, it’s not crystal clear and I wouldn’t be surprised by anything this company tries.
