Called my direct Cisco line on my work phone. Knew who I was and what my position in the company was. Thought it might be a vendor. Rattled through speech script so quickly that I realized this was a call scam.
Received 3 calls within one hour at my work phone. Did not answer any of them. Two did not leave messages, third call no message (just lots of background call center noise and could hear accented male voices.)
