Did not leave message, Spam caller for sure

Asian voicemail hangs up 1.5 seconds after answering

Caller: Franklin from Asource(?)

Franklin from ASource lied his way through reception to ask about our needs; sounded like a Philippines accent. Time waster.

Guy named Franklin called my workplace and asked for my boss (similar to someone else that's posted here before) seeking advice, when I said my boss was not available he asked to speak to someone else to help him and I asked if he had been referred by someone, he said yes a friend. When I asked him who his friend was he said he would call back when my boss was available and hung up. Very suss, so I checked the number and found other scam comments

Received a call at work (ccountants office) a man with an american accent asked for the boss using his first name only and when i said he isnt available and asked to take message he said what is your name i told him and he said ok thank you and hung up. so i rang back asking him what the deal was do you want to leave a message and he said no i will get in contact with boss another time.
