In this lab, you will construct and become familiar with the VoIP lab topology to be used in subsequent labs. The lab topology contains a total of three Cisco routers. However, some of the labs can be adapted to only two routers.
Following is a list of required lab equipment:
Three Cisco routers running Cisco IOS Software Release 12.3(1) or later. (The IOS should support the H.323 Gateway and AutoQoS features.)
- Router R1 should contain one serial interface and one FXS port.
- Router R2 should contain two serial interfaces.
- Router R3 should contain one serial interface and one FXS port.
