CCIE Routing and Switching Practice Labs

• Configure a basic VoIP connection between R3 and R4. Consider the R3 local number to be "33" and R4 local number to be"44."

If you configured this correctly as shown in Example 6-55, you have scored 3 points.

• Configure your dial peers to provide silence when the remote party is not speaking. You can assume that Voice Activity Detection (VAD) is enabled.

You have a VoIP peer configuration and you need to disable VAD in order to have a better voice quality.

If you configured this correctly as shown in Example 6-55, you have scored 3 points.
