It is not allowed for a woman to call the Adhan, according to all the reports. Going against this is going against the way of the believers.

Broadcasting the Adhan from the mosques by means of a recorder and the like is not sufficient and is not permissible with regard to this act of worship. The Muslims must give the Adhan directly for each and every time of prayer in each mosque.

Several versions of the adhan have been narrated in sound reports from the Prophet (peace and blessings of Allah be upon him). It is Sunnah to use all the versions that have been narrated from him in order to revive the Sunnah and to put an end to disputes and differences.

It is not prescribed for women to say the Adhan and Iqamah for prayer, whether they are praying individually or one woman leads the others in prayer.

The Adhan was prescribed at the time of the Messenger of Allah (peace and blessings of Allah be upon him) in Madinah, after a dream seen by one of the Companions.
