What happens to connect a local telephone call?

To connect a local telephone call, the caller's phone sends a signal to the local telephone exchange, which identifies the number dialed. The exchange then establishes a dedicated circuit between the caller and the recipient's phone, allowing for two-way communication. This process typically involves routing the call through a series of switches and may utilize copper wires or fiber optics, depending on the infrastructure. Once the connection is made, the phones can communicate until one party hangs up.
