There is an easy answer - the operator is trained to ask for names and contact information on every call; all tech support, operators and customer service representatives do. If she doesn't there is a chance her call will be monitored and points will be destructed from her call score, affecting her employment. No, QA might be cool and ignore this obviously prank cool, but do you think QA at the NSA will be cool, laid-back people when it comes to procedure?
