Same thing happened to me. I work for Schneider Electric. That number belongs to the factory that houses our APC subsidiary (battery back ups, data center products, etc).
For Once- This was actually a legit call. Caller was polite, asked for a co-worker by name and then identified himself, the company and reason for the Call when asked. Said they were Schneider Electric calling to schedule a routine preventative maintenance appt for our IT environment.
The party was polite, but avoided the direct request to identify themselves. Requesting to speak to someone in a department that doesn't accept in-coming calls per our No Solicit Policy.
