How a Calls Works

This overview explains the process of how long-distance calls are routed by various carriers in Chicago, such as Blue Mile and Paetec. When a call is initiated, it is picked up by a server, typically of the carrier selected. The call is then routed to its destination through the least cost effective path available, involving various local and long-distance switching offices. The routing may include carriers like AT&T and Level3, which ensure calls are directed efficiently based on their routing plans. Discover how technology manages long-distance communication seamlessly.
