Is there a word that means "connected to a conversation, being able to hear, read or any similar phrase" for "video conversation, chat, phone conversation"? I am trying to think and I can't find a very idiomatic way of saying this. Could you also provide with an example sentence, or a few of them? "Be on the line" can be used for phone conversation, but what about other form of communication like radio, video chat, etc?
