Only if you don't hang up afterwords. If you notice, I am not advising anyone to actually do that. It was just an idea, a hypothetical situation and I was not advocating people to do it. I said if you were a lawyer, it seems like you could get cases this way. But I am not, so I didn't know the rule. But there have been plenty of times where I have told a collector the call is being recorded later in the conversation.
I'm sure you could still record calls with them violating, if you are supposed to tell them in the beginning, because alot of them just assume that individuals are saying that but not actually recording the call.
I'm sorry you were concerned about very bad advice as I am not advising anyone, and was just musing.
