Narrative:

I was working the controller in charge position, in charge of the area at my center. The controller at a radar position coordination a descent to 5000 ft with (who he thought was) ind approach controllers. But, he was actually talking to the huf approach controllers, which is the adjacent approach control facility. Huf approach approved the descent, ind did not. The aircraft was descended into ind approach airspace without prior coordination.
