called and left no message

I have seen this number before on my caller ID and ignored it.  This time I picked up and it as a recorded message from "Allison" about a carpet cleaning special in my area.  She did not identify the company.  She said to press "1" to oder the carpet cleaning service and press "8" to be removed from the call list.  I am on the do not call registry.  I decided to call the number to see who would answer.  What I found out was a surprise.  It turns out that the number is a sex line for "ho**y men".  I did not listen to the rest of the message.
