That is a trick to get you to say "yes". Never answer an unknown caller with "yes". They are recording your conversation and will splice that "yes" onto "Do you agree to accept this offer?".
Very interesting - call today showed the caller-ID as:
13144499980
1(862-236-1252
Didn't answer - but you can see the notes above for the top number,
and if you look up the (816) number, there are at least 14 pages of notes about the various spams we all know and send curses toward.
Interesting that they linked the two spoofed #s.
