Implementing and Operating Cisco Collaboration Core - CLCOR

Explore IP-based call signaling in Cisco Collaboration Core, covering phone bootup, DHCP/TFTP, and signaling protocols (SIP, H.323, Skinny). Learn phone registration, VLAN separation, and on-cluster call setup.

Explore how a Cisco sip call initializes from uac to ucm, covering endpoint discovery, permission and bandwidth checks, logging, and session description protocol (sdp) negotiation for rtp.

Explore how Cisco Unified Communications Manager integrates with ldap, enabling synchronization and authentication with Active Directory to provision end users and application users.

Enable LDAP synchronization and authentication to centralize user data from Active Directory into Cisco Unified Communications Manager, map attributes to user IDs, and enable single sign-on.

Understand how access control groups in Cisco Unified Communications Manager grant role-based privileges to end users, manage overlapping permissions, and provision standard and custom roles.

explore feature group templates to simplify provisioning and automate line creation from LDAP, powered by universal line and device templates for directory numbers.

Explore manual, auto registration, bulk administration tools, and self provisioning for Cisco Unified Communication Manager, and compare their setup, advantages, and deployment impact.

Learn how to use the bulk administration tool to bulk add, update, and delete phones in Cisco Unified Communications Manager, including import/export, templates, and validation.

Enable self provisioning in Cisco Unified Communications Manager for end users to add phones with minimal effort. Configure feature group templates, LDAP integration, and authentication to support automatic provisioning.

Explore how codec selection affects bandwidth, call quality, and encryption in voice over IP; compare G.711, G.722, G.729, and iLBC, and examine packet structure and bandwidth calculations.

Explore the dial plan and endpoint addressing in Cisco Unified Communications Manager, learning how call routing, digit manipulation, calling privileges, and emergency dialing rules shape reliable, location-aware communications.

Explore endpoint addressing in Cisco UCM, assigning directory numbers and directory URI aliases to internal endpoints, and balancing two-stage dialing with direct inward dialing and URI dialing.

Learn how Cisco Unified Communications Manager routes calls from a local endpoint or gateway, analyzes targets, and chooses the longest prefix match via intra site, inter site, and PSTN routing.

Explore the addressing method and digit-by-digit analysis in sip and unblock dialing, html keypad markup, and zip dial rules to optimize routing with Cisco Unified Communications Manager.

Explore variable length dialing and overlapping patterns, exclamation marks and hash keys, and urgent priority in Cisco Unified Communications Manager to reduce post dial delay and inter-digit timeout.

Explore MGCP gateways and their centralized dial plan for simplified configuration, and cover path selection with route pattern, route list, route group, local route group, and pre backhaul.

Explore implementing voice gateways to route calls between PSTN and IP networks using inbound and outbound dial peers, Cisco Unified Border Element, with server groups and destination patterns.

Learn to implement class of service in Cisco call manager to enforce privileges, time of day routing, 911/vanity numbers, and call accounting via client matter codes and force authorization codes.

Discover how to prevent toll fraud in Cisco collaboration systems by applying class of service and restriction rules, time-of-day routing, least-cost routing, and force authorization code.
