Catalog Description [§335.2] (Insert new/revised description in space below):
Covers telecommunications and IP Telephony. This course discusses unified communications,
Public Switched Telephone Network (PSTN) components and connections, Voice over Internet
Protocol (VoIP) network components, gateways, voice ports, analog ports, digital ports, dial
peers, 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 are able to perform these skills using
Cisco Unified Communications Manager Express (CME), and Cisco Unity Express (CUE).
Students also becomes familiar with IP-PBX (Asterisk) and the environment in which it
operates - both in terms of operating system and telephony connections (traditional and IP) and
with the installation, configuration, and basic operation. This course can be used to help
students prepare for the Cisco Certified Network Associate (CCNA) Voice certification exam,
as well as the Digium Certified Asterisk Administrator (dCAA) certification exam. A course
fee is required.
