What is the ruling on communal Talbiyah and Takbir?

The collective Talbiyah in a single voice, whereby some pilgrims follow the Talbiyah of one of them, is not reported from the Companions, and it goes against the prescribed method, which is for each individual to perform the Talbiyah on their own. However, there is no harm in people raising their voices collectively with the Talbiyah without adhering to a specific method, along with men raising their voices.
