[B]I'm not sure what the C stands for. Do any of the phones work?

All of her other sets don't have the C in their ID. I did get one to work after many trys. We have had 3 sets replaced and they all seem to have the same problem.The supplier tells us the sets are good. We have had this problem on 2 different systems with 3 different sets. Any ideas?
