Our business receives 2 or 3 calls a day from this number.  When we answer it, there is dead air for a moment, then call disconnects.  Once or twice, I would start to hear a recorded message but not enough to determine who is calling.  A similar number from Worcester, MA (ending in 4909) has been associated with Verizon Wireless, supposedly calling regarding a past due bill.  We DO have a Verizon Wireless business account, but this is not the number they call from when there is any sort of issue, so I do not believe it is legitimately Verizon Wireless.
