I'm not clear about the way the phone is creating the loop. You mean that both phone ports are connected to the same switch? If this is the case and STP is still running on the switch, it should block one of its port and put it in backup role (likely to be alternate if the phone is connected to two different switches). By checking the role of your access ports, you should be able to easily identify which ones are looped back through a phone.
