When the phone rings, it's likely as not going to be a cell phone.
The Illinois Commerce Commission says 48 percent of the state's households are wireless-only. And, says AT&T Illinois president Paul La Schiazza, most of the customers with landlines are really using modern voiceover Internet protocol (VOIP) that comes as part of their Internet service.

“When you combine wireless and (VOIP), there's really only about 18 percent of the households left that are using the plain old copper line,” says La Schiazza. A longtime bone of contention between AT&T and the government is the phone company is required to make the copper-based technology available to 100 percent of the customers, even though fewer than one in five use it.
“Eventually, everyone will be on a new modern landline, a wireless connection, or a combination of the two,” says La Schiazza, “and it's just happening on its own.”
