Information about Planning your configuration

Before configuring Cisco Unified CME, you should understand the following concepts:

1 System design

2 Toll Fraud Prevention

3 configuration Methods Summary

4 Cisco Unified CME GUI

5 Workflow

First : System Design

Maximum number of Phones

Maximum number of directory numbers

Telephone number scheme

Maximum number of buttons per phone

(1)Is there an existing PBX or Key System that you are replacing and want to emulate ?

(2)Number of phones and phone users to be supported?

(3)Do you want to use single-line or dual-line DNs

(4)what protocols does your voice network support ?

(5)what call transfer and forwarding methods must be supported ?

(6)what existing or preferred billing method do you want to use for transferred and forwarded calls ?

(7)Do you need to optimize network bandwidth or minimize voice delay ?

 Second : Toll Fraud Prevention

(1) Disable secondary line tone on voice port

(2)Cisco router access control lists

(3)Cisco unused SIP and H.323 ports

(4) Change SIP port

(5)SIP registration

(6)SIP Digest Authentication

(7) Explicit incoming and outgoing dial peers

 Third : Configuration Methods Summary

(1) Cisco IOS command line interface 

(2) Cisco Unified CME GUI

Voice Bundles

Voice Bundles include a Cisco Integrated Services Router for secure data routing, Cisco Unified CME software and licenses to support IP telephony, Cisco IOS SP Services or Advanced IP Services software for voice gateway features and the flexibility to add Cisco Unity Express for voice mail and auto attendant capablilities , Voice bundles are designed to meet the diverse needs of businesses world wide , To complete the solution , add digital or analog trunk interfaces to interface to the PSTN or the host PBX, Cisco IP Phones, and Cisco Catalyst data switches supporting Power-over ethernet (PoE)

Workflow :

(1) Install Cisco router and all recommended servics hardware for Cisco Unified CME

(2) Download recommended Cisco IOS IP Voice or higher image to flash memory in the router 

(3)Download recommended Cisco Unified CME software including phone fireware and GUI files

(4) configure separate virtual LANs for data and voice on the port switch

(5) enable calls in your VoIP network 

    Define DHCP

    set Network Time Protocol(NTP)

    configure DTMF Relay for H.323 network in              multisite installations

    Change the TFTP address on a DHCP Server

     Enable OOD-R

(6)configure Bulk Registration

   set up Cisco Unified CME

   set data and time parameters

   Block Automatic Registration

   Define alternate location and type of configuration files

   change defaults for Time Outs

   configure a redundant router

(7) create directory numbers and assigning directory numbers to phones

    create phone configurations using extension assigner

     create configuration files for phones

     reset or restart phones

(8) Connect to PSTN
