I just got a call from this number. Missed it on my cell but saw it on my work line and didn't recognize the number. They did leave a message with the extension to call back to. I had just finished my registration on the Troops To Teachers site and it was them calling to ask a question. So, legit number.

Call Mask
This is just a call mask or trunk line for the base hospital in Pensacola. As someone in Network Engineering who does Call Manager stuff, this is fairly common and not "tapping into your system". Generally, a call will be masked and then when you call the masked number it will take you to a clients help line.
