Making Decisions

How would you handle a situation that teetered on the edge of unethical, but was not against company policy? 

For example, there is no clear rule in your employee handbook forbidding romantic relationships. However, the receptionist, Alyssa, has begun dating a salesperson, Connor. The receptionist will occasionally receive cold calls from potential clients. There is an assumption on the sales team that Connor may be getting routed these cold calls due to his relationship with Alyssa.
