IP Telephony Design (IPTD) 1.0
Overview/Description
Successful IP telephony implementations must start with a
detailed and well-planned design. As prospective designers of IP
telephony solutions, students of this course will learn about
designing, or redesigning, the enterprise LAN and sizing WAN links
to support IP telephony. Students learn about sizing and
positioning voice gateways, calculating the processing power
required to support IP telephony, positioning and sizing Cisco
CallManager clusters, and designing the dial plan and emergency
services. Students also learn about securing the IP telephony
solution.
This critical course in IP telephony takes a very "real-world"
approach to the course materials, allowing students to practice IP
telephony designs using mock scenarios based on real network
topologies. Comprehensive design exercises include a multi-campus,
multi-site organization that is migrating from a circuit-switched
telephony network to a packet-switched telephony network.
Target Audience
This course is recommended for any system or field engineers
that are responsible for designing and/or implementing Cisco IP
telephony solutions. This course is also recommended for any
students attempting Cisco IP Telephony Design certification.
