So those would not be picked up merely by listening to the correct ATC stream on LiveATC. Even if the next audio frequency were known, it might not be supported by LiveATC. Also, ATC facilities often "combine" sectors during periods of low(er) traffic; particularly in the later evening/early morning hours. So that could further complicate getting the correct audio channel.
