Know the reasons for migrating voice from a traditional to integrated architecture. Cost, security, and additional services all contribute to the reasons for migrating to an integrated voice network solution. A unified group of designers and administrators is also a benefit of migration.
Know the traditional voice network devices. Traditional voice network devices include a PBX switch or Centrex line, tie-lines, and trunks.
Know the benefits of Cisco’s SAFE architecture design. SAFE helps prevent some of the most common type of network attacks with a defense- in-depth approach using modular design.
Remember the network targets of a SAFE architecture. Routers and switches share common security design considerations such as controlling management access and disabling unused services or ports. Secure your hosts and networks by keeping them up-to-date with security-related patches. Additionally, monitor them with IDSs. Secure code and applications are the foundation to secure computing.
