Your local dial tone provider (AT&T, Verizon, XO, Frontier, etc.) gets your incoming calls. If line one is busy that dial tone central office sends it out on another pair and if that line is also busy sends the call out on still another pair.

No phone system can control the calls that are coming into the central office and make them be in hunting, ONLY the dial tone provider can do that.

You have the headsets plugged in or what?
