If your orders do not give you telephonic communication at specified times, then file a motion to have it - you want specific days/times which your child is available to talk to you on the phone and if the child isn't home, then the call has to be returned within so many hours. If that is not in your orders, then your attempts mean nothing and neither would your notice. She can't be held in contempt or viewed as denying your rights per the orders, if it's not in the orders.
