Is my husband's attorney for an FRO hearing allowed to contact me to discuss the case over the phone?

It is not improper for the lawyer to reach out to you to discuss an adjournment request or to ask you if you are interested in exploring other options for resolution of the matter so long as he / she is respectful and does not attempt to intimidate or pressure you with the contact. If you dont want to talk with the lawyer, you can simply tell him that you are not interested in discussing it with him and from that point forward, he should not contact you further. Alternatively, you have the right to ask the lawyer what he is suggesting as a way to resolve the matter peacefully and then you can evaluate whether the suggested solution makes sense to you.
