Catalog Description: Advanced course. The course gives a more detailed
understanding of the topics in telecommunications. Topics include: unified
communications, PSTN network components, VoIP network components,
gateways, voice ports, analog ports, digital ports, dial peers, PSTN network
connections, IP-PBX, and network configuration to support VoIP
communications and voicemail. The focus of the course is on basic IP telephony
installation, configuration, and maintenance of small to medium sized IP
Telephony solutions. Students will complete this by using Cisco Unified
Communications Manager Express (CME), and Cisco Unity Express (CUE). The
student will also become familiar with an IP-PBX (Asterisk) and the environment
in which it operates, both in terms of operating system and telephony connections
(traditional and IP) — and students will become acquainted with the installation,
configuration and basic operation of an IP-PBX (Asterisk). This course can be
used to help students prepare for the CCNA Voice certification exam as well as
the dCAP (Digium Certified Asterisk Professional Certification). A laboratory fee
is required.
