CCNA Voice (IIUC)

Αντικείμενο Εκπαιδευτικού Προγράμματος / Description
IP Telephony is the most requested new course offering within the Industry community. The course content will focus on lab activities surrounding voice and data convergence, but does NOT include traditional on-line curriculum or assessment. IP Telephony will focus on entry level skills required to implement IP Telephony in a SOHO environment.

The Cisco IP Telephony course provides an introduction to converged voice and data networks as well as the challenges faced by its various technologies. The course presents Cisco solutions and implementation considerations to address those challenges. In this course, students will learn about Cisco CallManager Express (CME) architecture, components, functionality and features. They will also learn some Voice over IP (VoIP) and Quality of Service (QoS) technologies and apply them to Cisco CME environment.

The focus of the course is:

• Call Manager Express
• Connecting to a PSTN network
• Connecting from one router across a WAN to another router running CME
• Connecting from one CME enabled router to another CME enabled router

Σκοπός Εκπαιδευτικού Προγράμματος / Objectives
Upon completing this course, the learner will be able to meet these overall objectives:

• Determine the relevant critical business and technical needs in order to develop a Cisco IP Telephony design framework in a SOHO environment, including the choice of signaling type and encoding methods.
• Select the appropriate hardware and software components to support a proposed SOHO IP telephony design
• Determine which high availability issues would influence the selection of network hardware and software for an SOHO environment.
• Design the appropriate dial plan to support SOHO design requirements
• Describe the similarities and differences between PSTN and VoIP including call transport, call signaling and bandwidth requirements
• Describe the technologies used in Voice over IP and how they differ from PSTN technologies.

Determine how PSTN connectivity issues influence SOHO hardware and software selection.
Understand and be able to configure various connection types to the PSTN.
Explain the benefits of hierarchical and scalable dial and numbering plans –
Install an IP Telephony solution in a SOHO environment using CME
Configure Cisco Call Manager Express to support IP Phones
Secure an IP Communications network
Describe effective troubleshooting methods to resolve issues in SOHO IP Telephony networks
Use appropriate troubleshooting methods to determine and solve QoS issues in an SOHO IP Telephony networks

Πού Απευθύνεται / Audience
The target audience is individuals desiring to continue their post-CCNA preparation in designing, maintaining and troubleshooting an SMB IP telephony network.
