I could hear what sounded like office chatter in the background and could hear someone handling the phone. I said hello and they hung up (good!). A search of telephone prefixes shows 143 doesn't exist. Be suspicious or let them leave a message.
Definitely telemarketer. Said "Can I please speak with the Owner or President of your company", got all stand-offish when I told him I couldn't put him through but I could take his info and pass it along.
Exactly the same experience when I said the owner is not available he any manager I said we don't want to talk he said I am from the police news will tomorrow and hang up.
