it's the main number for the VA in Pittsburg all the clinics use that line for out going calls they will leave a message for you to call back a clinic number to set up your appointment duh
It is the VA Hospital in Pittsburgh, a business call for my son.
But, even if they had been looking for someone else and had confused my number with that of a veteran, I'm happy to answer these mistaken but non spam calls to clarify if they are calling the wrong number by mistake.
I just got two calls in a row. Didn't recognize so didn't answer. Then I saw I had a message. Yep, it was out of the Pittsburgh VA hospital. It was actually from my son, who is a patient there presently. Must be one of their trunk lines for outgoing calls.
