Have gotten lots of calls from this number to my office line. The voice mails they have left are the tail end of a robo message and all that can be made out is the ext of the phone number they have supposedly given. Tried calling back and it's a non-descript message - no company name, just "Please hold because your business is very important to us"... I actually did wait and about a minute later it came back saying "the person at the extension you are dialing is not available and the mailbox is unable to take messages at this time" - still no mention of the company or the person I was calling. Because I've gotten so many of these calls at random hours and they've never left an actual message that I can make out, I am going to go ahead and say this is spam. Have blocked the number so they cannot call us again.
