Musannaf Ibn Abi Shaybah 14537 — A person in ihram: when does he stop

Amr bin Maymun said: I performed Hajj with Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) for two years, one of them in the year in which he was martyred. He kept saying the talbiyah until he had stoned Jamrat al-Aqabah from the bottom of the valley (and then he stopped the talbiyah).
