Who called from 2672259088

When the machine picked up caller hung up.

Another 267 number that calls frequently.  Rings 3 times and hangs up.  No message?????

Calls my job at least 3 to 4 times a day. No one is on the other line.
I hate these calls. I know they are bogus but i have to answer every call that comes in if not it gets noted on my record.
