Human Factors
I operated [a flight pairing] which ended the evening of [date] in ZZZ for a scheduled 11 hour layover with a XA:50 report the morning of the [date.] At XB:11 east coast time Crew Scheduling called me and interrupted my crew rest to notify that my pairing had been modified. This modification included a later report time and a 'soft' reset of my Out of Duty Time Clock. The modification also changed the pairing from a three day trip to a two day trip ending in ZZZ1. This was mid rest interruption number 1. Upon arriving in ZZZ1 I was notified at XC:49 Central time that I was now assigned a XD:00 short call for the following morning; 12 hours and 11 minutes later. At XC:56 central time I was contacted by crew scheduling. They 'released' me to rest and assigned pairing to me which was to report later that same day at XD:25. The flights to ZZZ2 and return flight were to operate over 8 hours later than displayed on the pairing due to aircraft availability. My second mid rest interruption occurred at XE:05 when Crew Scheduling again contacted me via phone waking me. I answered the phone and the scheduler was 're verifying' that I had acknowledged my assignment. I was unable to sleep again after the second contact.
