Who was the Prophet Muhammad's (peace be upon him) muezzin in Medina?

The Prophet, peace and blessings be upon him, had several muezzins in Medina, the most prominent of whom was Bilal ibn Rabah, may Allah be pleased with him. He had one of the best voices among the Companions, as mentioned in the hadith of Abdullah ibn Zayd, where the Prophet, peace and blessings be upon him, said to him: "Stand with Bilal, for he has a more resonant and far-reaching voice than you. Impart to him what was told to you, and let him make the call."
