Air duct cleaning scam - are you on meds?
The two most common telemarketing scams I get are solar energy companies and this - air duct cleaning.
I have several of these, but this agent was pretty cool about such an odd interaction. As you can tell from the looong cut-through time, these guys are using an autodialer. The little "bloop" you hear is the agent popping into the conversation. The sound is an Asterisk "meet-me" tone. This gives us a clue as to the software they're using. The agents likely don't have to touch their telephones.
Anyway, this one is brief. But as you can hear, even when the robot fails, the agent still figures it's a human on medication. Because, after all, who would suspect an interactive robot?
Enjoy and thanks for listening...
