Yes, his ability to talk to his daughter is disturbing to me, too. Was that something you agreed to, or did the judge order it over your objection? This is the same child that had to climb out a WINDOW to escape, as the SWAT team surrounded the house. You can bet he will manipulate her in those phone calls--she is a witness, and he knows it. I'd try to put a stop to that, and if the judge insists, be sure the prosecutor's office knows he is talking to her on the phone. The prosecutor's office can usually get audio recordings of calls made from the jail.
Talk with an advocate, or if you have a civil attorney for the protective order, talk to him or her about stopping that communication.
