Making Talbiyah as a Group in Chorus

What is the ruling regarding making the Talbiyah as a group in chorus?

Some of the pilgrims make the Talbiyah as a group in chorus, so one of them is either at the front, middle or behind and makes the Talbiyah while all of them follow him in chorus.

This has not been mentioned on the authority of any of the companions. Rather, Anas Ibn Malik said:

"We were with the Prophet (Peace and blessings be upon him) (on Hajj Al-Wada' "farewell pilgrimage") and from amongst us were those who recited 'Allahu Akbar' and those who recited 'La ilaha ill-Allah' and those who recited the Talbiyah."

This is what has been legislated for the Muslims, whereby each one then makes Talbiyah on his own without joining together with others.
