After rotation PF (pilot flying) had difficulty turning left to HDG 330; I thought he was rusty. Had him hand fly to about FL180. When we put the auto pilot on we had the AP LWD Caution msg. We ran the QRH and noticed the aileron trim did not respond or move. ACARS Dispatch and they mentioned deferring the aileron trim. I then noticed the Aileron Trim circuit breaker was popped. I attempted to contact Dispatch through AIRINC prior to ZZZ. Dispatch could not hear me. We advised ATC for flight control malfunction. Test items ran no brace I briefed the passengers I did not have the go through planned diversion with passengers. I was very surprised that Dispatch had a known bad headset. She knowingly continued to act as a Dispatcher with a bad headset. I could not hear her on AIRINC and when I called on the phone I could not hear her. She said she knew it was bad and they needed a new one. If I knowingly operated an airplane with a bad headset I'd be in major trouble.
Air carrier check airman reported student difficulty with directional control after takeoff.  Discovered failure of aileron trim during climb. Returned to base and was concerned about communication with company personnel due their lack of adequate equipment.
