Campus Infrastructure Considerations

To ensure successful implementation of Cisco IP Telephony Solutions, you must

first consider your LAN infrastructure. Before adding voice to your network, your

data network must be configured properly.

You can use these concepts and implementation techniques regardless of whether

you have a headquarters with tens of thousands of users or a small branch with

fewer than a hundred users. However, the size of the network determines the

actual components and platforms you will select and the details that determine the

scalability, availability, and functionality of your network.
