In this lab, you will configure and test router R1’s FXS port using the topology you constructed in the lab exercise for Chapter 2, “Analog and Digital Voice Connections.” Recall that an FXS port allows you to connect end stations, such as analog phones, fax machines, and modems, into a voice-enabled router.
Figure 3-19 illustrates the lab’s physical topology and IP addressing.
In this task, you will issue commands to configure various parameters on an FXS port.
Complete these steps:
Enter voice port configuration mode for the FXS port ...
