From what has been reported on the forum these telephone assessments have been taking around 45-60 minutes.
I would write a bullet list of your partner's issues and keep it next to the phone, it has also been advised to have a glass of water available.
I would start the call by saying that your partner is having problems with their breathing and ask whether you can take over the assessment if necessary, you will have to be guided by the assessor's response.
