CCNA VOICE 640-461 CERT GUIDE CHAPTER 2 Understanding the Pieces of Cisco Unified Communication Benefits of VoIP for Business:
Reduced cost of Communicating: Forward calls over WAN links instead of expensive PSTN lines Reduced cost of cabling: Cost cut in half, because of the use of existing Ethernet lines Seamless voice networks: Where there is data networks there can be voice networks Take your phone with you: Because the phone gets configuration by MAC address, the phone can
be moved seamlessly IP Softphones: Computer based logical phones that perform all functions of physical phones. (IP Communicator) Unified e-mail, voice mail and fax: All services can be stored and delivered from a single database Benefits of VoIP for Business continued:
Increased productivity: VoIP can forward to multiple devices reducing phone tag Feature-rich communication: Data applications can be integrated with the phone. Open, compatible standards: Different vendors devices can integrate on the same VoIP network Will the traditional phone system survive?
Most believe that it will be replaced by VoIP. VoIP Structure: Endpoints: Phone, Wireless/Cell Phone, Video Phone, IM Client Applications: Voice mail, Conference Call Applications, Call Center Applications, 911 services Call Processing: Unified Communications
Infrastructure Layer: Infrastructure Layer: Infrastructure Layer: Traditional PBX systems are up 99.999% or down for only five (5) minutes each year!
Configured for fast failover Include Quality of service (QoS) in network development Can existing equipment provide service? Call Processing Layer: Cisco Unified Communications 500 (UC500): Stand alone solution, supports forty-eight (48) users
Cisco Unified Communications Manager Express (Call Manager Express CME): Supports up to two-hundred fifty (250) users depending on equipment Cisco Unified Communications Manager Business Edition: Supports up to five-hundred (500) users Cisco Unified Communications Manager
(formerly CallManager) Supports thirty-thousand plus users (30,000+) Cisco Unified Communications 500 (UC500) UC500 Features: Phone support for eight (8) to forty-eight (48) phones

Cisco Unified Communications Manager Business Edition: Cisco Unified Communications Manager Business Edition continued: Linux based Five-hundred (500) phones supported All-in-one solution
Cisco Unified Communications Manager: The call processing component that provides features and functionality Cisco Unity Connection: Integrated Voice-mail solution Cisco Unified Mobility: Allows users to be reached from a single phone number by redirecting calls to multiple devices
Cisco Unified Communications Manager: Added benefits over Business edition Redundancy Scalability Number of users is thirty-thousand per cluster Multiple cluster support Redundancy support
Server based Application layer: Cisco Unity Express Cisco Unity Connection Cisco Unity Cisco Unity Express:
Cisco Unity Express: Smallest Unity Solution Runs from either a Flash Module or Hard Drive Can be added to multiple platforms Flash Advanced Integration Module (AIM) plugs directly into router motherboard
Hard Drive runs as a network module Runs as a Linux based program and provides: Voice-mail Automated Attendant Message retrieval via e-mail, phone, or web interface Cisco Unity Connection:
Server solution providing same services as Unity Express With additional dedicated server modules it can scale up to seven-thousand five-hundred (7500) users Cisco Unity: Additional services of:
Forward voice messages as e-mail attachments Users can leave messages for multiple users with a single call Users can listen to e-mail messages using text to speech users can respond to e-mail messages via phone with audio attachment Users can view faxes as TIF files via e-mail
Interactive Voice response / Auto Attendant: Provides Prompt and Collect features Call Redirection Cisco Unified Contact Center: Can cycle through multiple call agents. Automatic Call Distributor (ACD)
Can direct calls to appropriate agents Dedicated server based application Can use Computer Telephony Integration (CTI) Information about caller placed on screen Uses Caller ID Supports Chat Supports Web collaboration
e-mail integration Additional Applications: Cisco Unified Meeting Place: Provides a multimedia conference solution Cisco Unified presence: Provides information of a users availability and reach ability Cisco Unified Mobility: One single contact
