Is it permissible for the wife to use the phone without her husband's consent, especially if it is due to harassment or the husband's fear of someone he dislikes entering his home through the phone?

Married life is based on kindness, good companionship, and consideration for both parties' feelings. If the wife uses the phone for permissible matters and is known for her uprightness, the husband should not forbid her. However, if there are many disturbances [harassing calls] and the wife perceives her husband's dislike of her answering the phone, she should refrain from doing so out of consideration for his feelings. But if the wife insists on using the phone despite disturbances or suspicion, she is not allowed to use it except with her husband's permission, because he is the guardian and maintainer of his household, and this affects his honor and dignity. Women have been forbidden from speaking [to non-mahram men] except with their husbands' permission, because it is a source of falling into indecency due to the whisperings of Satan. It is permissible with his permission if there is no unlawful seclusion and the conversation is with non-mahram men.
