One of the issues my S13 had was he was unable to tell his dad what he thought so all his angst became physical symptoms i.e tummy and headaches.
After counselling he learnt that he should tell his dad how he felt and did!
Your D is very strong, although she is hurting, as she left him a message and told him exactly how she felt about him not answering his phone.
I would be inclined to see if D and your H can sort this out between them as your D seems to know her mind. Eventually as we all know he will have to face these issues. Maybe check with your D to see if your H has apologised etc. She may need your support if he continues to ignore her.
