Cisco CIPT2 6.0: IP Telephony Security

This course is included in our On-demand training solution.

Overview

Cisco Unified Communications Manager supports several features that increase the security level of a Cisco Unified Communications solution, including the application of cryptographic features. In order to implement, manage, and troubleshoot a secure Cisco Unified Communications Manager deployment, it is important to understand the underlying cryptographic fundamentals and concepts, and to understand how Cisco Unified Communications Manager cryptographic features rely on a Public Key Infrastructure (PKI) to provide encryption and authentication features. This course describes cryptographic basics and how they are used by Cisco Unified Communications Manager security features. The course also explains how to implement these security features. This course is one of a series from two SkillSoft learning paths, which cover the objectives for Cisco exam 642-456 CIPT2. This exam is one of five required qualifying exams for the CCVP (Cisco Certified Voice Professional) certification.

Target Audience

The primary audience for this learning path will be a range of established IT professionals. They will have a thorough understanding of network and Cisco technology basics, and so good computer literacy along with a solid technical acumen can be assumed; individuals seeking the Implementing Cisco Unified Communications IP Telephony certification and those individuals targeting the Cisco Certified Voice Professional (CCVP) certification.

Prerequisites

Working knowledge of converged voice and data networks; working knowledge of MGCP, SIP, and H.323 and their implementation on Cisco IOS gateways; ability to configure and operate Cisco routers and switches; ability to configure and operate Cisco Unified Communications manager in a single site environment; Cisco ICND1 v1.0, Building Cisco Multilayer Switched Networks (BCMSN) v3.0, Cisco Voice Over IP (CVOICE) v6.0, and CIPT1 v6.0.

Expected Duration

180 min.
