Received call on business line from this unknown caller at 1037 MST.  Called back to verify caller's identity and reached a female voice-recording that did not disclose the caller's name or business but stated "office hours" were 9 am to 2 pm weekdays [the recording also noted that they are closed on Wednesdays].

Since we have no current business relationships with anyone located in Phoenix AZ, we added this number to our calling-blocking list.
