How to fetch current live channel list?

[rinav]

At any given point in time, How to fetch current live channels that a user can join? Is there are callback that returns a list of all the channels that are live currently along with some meta info about the channel like total time the channel has been in live state?

This is an interactive audio scenario when a user can join a channel with audience as a profile.

Also How to detect if a channel name already exists and is live correctly and that this name should not be allowed?
eg Two broadcasters cannot use same name if one is already live in broadcast state
