Before You Begin

This module describes general decisions that you should make before you configure Cisco Unified Communications Manager Express (Cisco Unified CME), information about tools for configuring Cisco Unified CME, and the work flow for creating or modifying a telephony configuration.

Prerequisites for Configuring Cisco Unified CME

Note Even though the worksheet set is for configuring a Typical (recommended) installation of an IP telephony system using Cisco Unified Communications Express - QCT, the information is required to create a telephony configuration using any of the configuration methods.

•

Base Cisco Unified CME feature license and phone user licenses that entitle you to use Cisco Unified CME are purchased.

Note To support H.323 call transfers and forwards to network devices that do not support the H.450 standard, such as Cisco Unified Communications Manager, a tandem gateway is required in the network. The tandem gateway must be running Cisco IOS release 12.3(7)T or a later release and requires the Integrated Voice and Video Services feature license (FL-GK-NEW-xxx), which includes H.323 gatekeeper, IP-to-IP gateway, and H.450 tandem functionality.

•

Recommended Cisco IOS IP Voice or higher image is downloaded to flash memory in the router.

•

VoIP networking must be operational. For quality and security purposes, we recommend separate virtual LANs (VLANs) for data and voice. The IP network assigned to each VLAN should be large enough to support addresses for all nodes on that VLAN. Cisco Unified CME phones receive their IP addresses from the voice network, whereas all other nodes such as PCs, servers, and printers receive their IP addresses from the data network. For configuration information, see the "How to Configure VLANs on a Cisco Switch" section.

Restrictions for Configuring Cisco Unified CME

•

Cisco Unified CME cannot register as a member of a Cisco Unified Communications Manager cluster.

•

For conferencing and music on hold (MOH) support with G.729, hardware digital signal processors (DSPs) are required for transcoding G.729 between G.711.

•

After a three-way conference is established, a participant cannot use call transfer to join the remaining conference participants to a different number.

–

Java Telephony Application Programming Interface (JTAPI) applications, such as the Cisco IP Softphone, Cisco Unified Communications Manager Auto Attendant, or Cisco Personal Assistant

–

Telephony Application Programming Interface (TAPI)
Cisco Unified CME implements only a small subset of TAPI functionality. It supports operation of multiple independent clients (for example, one client per phone line), but not full support for multiple-user or multiple-call handling, which is required for complex features such as automatic call distribution (ACD) and Cisco Unified Contact Center (formerly Cisco IPCC). Also, this TAPI version does not have direct media- and voice-handling capabilities.

Information About Planning Your Configuration

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

System Design

Traditional telephony systems are based on physical connections and are therefore limited in the types of phone services that they can offer. Because phone configurations and directory numbers in a Cisco Unified CME system are software entities and because the audio stream is packet-based, an almost limitless number of combinations of phone numbers, lines, and phones can be planned and implemented.

Cisco Unified CME systems can be designed in many ways. The key is to determine the total number of simultaneous calls you want to handle at your site and at each phone at your site, and how many different directory numbers and phones you want to have. Even a Cisco Unified CME system has its limits, however. Consider the following factors in your system design:

•

Maximum number of directory numbers—This number corresponds to the maximum number of simultaneous call connections that can occur. The maximum is platform- and version-dependent. To find the maximum for your platform and version, see the appropriate Cisco CME Supported Firmware, Platforms, Memory, and Voice Products document at http://www.cisco.com/en/US/products/sw/voicesw/ps4625/products_documentation_roadmap09186a0080189132.html.

•

Telephone number scheme—Your numbering plan may restrict the range of telephone numbers or extension numbers that you can use. For example, if you have DID, the PSTN may assign you a certain series of numbers.

•

Maximum number of buttons per phone—You may be limited by the number of buttons and phones that your site can use. For example, you may have two people with six-button phones to answer 20 different telephone numbers.

The flexibility of a Cisco Unified CME system is due largely to the different types of directory numbers (DNs) that you can assign to phones in your system. By understanding types of DNs and considering how they can be combined, you can create the complete call coverage that your business requires. For more information about DNs, see "Configuring Phones to Make Basic Calls" on page 165.

After setting up the DNs and phones that you need, you can add optional Cisco Unified CME features to create a telephony environment that enhances your business objectives. Cisco Unified CME systems are able to integrate with the PSTN and with your business requirements to allow you to continue using your existing number plans, dialing schemes, and call coverage patterns.

When creating number plans, dialing schemes, and call coverage patterns in Cisco Unified CME, there are several factors that you must consider:

•

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

•

What existing or preferred billing method do you want to use for transferred and forwarded calls?

Because these factors can limit your choices for some of the configuration decisions that you will make when you create of a dialing plan, see the Cisco Unified CME Solution Reference Network Design Guide to help you understand the effect these factors have on your Cisco Unified CME implementation.

Configuration Methods Summary

Your choice of configuration method depends on whether you want to create an initial configuration for your IP telephony system or you want to perform ongoing maintenance, such as routinely making additions and changes associated with employee turnover. Table 2 compares the different methods for configuring Cisco Unified CME:

Cisco Unified Communications Express - QCT

Cisco Unified Communications Express - QCT 3.0 and later versions is an optional web-based application provided by Cisco Systems to simplify installation of a new stand-alone Cisco IP Communications Express (Cisco IPC Express). Cisco IPC Express is a complete communications solution for the small office or enterprise branch office installed on a single Cisco router running Cisco IOS IP Voice or higher. Cisco IPC Express includes Cisco Unified Communications Manager Express (Cisco Unified CME) for call processing and peripheral services like Cisco Unity Express voice mail, Automated Attendant (AA), and support for IP-phone based XML and Telephony Application Programming Interface (TAPI) applications. Although Cisco IPC Express can support up to 240 phone users, this tool is intended for installing the typical configuration for 50 or fewer users, on a Cisco Integrated Services Router Voice Bundle.

Cisco QCT does not configure advanced features including but not limited to Cisco Unity Express customized scripts, overlay-dn, and advanced ACD (Automatic Call Distributor). You will be required to use Cisco IOS commands, Cisco Unity Express GUI or command line interface (CLI), and other Cisco configuration tools to configure advanced features after using Cisco QCT. After you fill in the required fields, Cisco Unified Communications Express - QCT generates the corresponding commands and uploads the basic telephony configuration to your Cisco router.

Cisco Unified Communications Express - QCT supports auto-discovery of installed hardware, so you can deploy an IP telephony configuration without having detailed knowledge of the modules installed in the router. Cisco Unified Communications Express - QCT prompts for common parameters needed to configure a Cisco Integrated Services router to support a complete IP telephony solution as a private-branch-exchange (PBX) with direct-inward-dial extensions or as a square mode key system.

Before using Cisco Unified Communications Express - QCT, the factory-default configuration must be loaded in nonvolatile memory and in the running configuration of the Cisco router to be configured. You can use Cisco Unified Communications Express - QCT to restore the factory default configuration on router to be configured.

After using Cisco Unified Communications Express - QCT, you can add any feature not supported by Cisco Unified Communications Express - QCT to the configuration by using Cisco IOS commands.

Cisco Unified Communications Express - QCT cannot be used to perform routine additions and changes associated with employee turnover. You can use the Cisco Unified CME GUI or Cisco IOS commands to modify the basic telephony configuration generated by Cisco Unified Communications Express - QCT.

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 capabilities. 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).

Cisco Unified CME GUI

The Cisco Unified CME GUI provides a web-based interface to manage most system-level and phone-level features. In particular, the GUI facilitates the routine additions and changes associated with employee turnover, allowing these changes to be performed by nontechnical staff.

•

System administrator—Able to configure all systemwide and phone-based features. This person is familiar with Cisco IOS software and VoIP network configuration.

•

Customer administrator—Able to perform routine phone additions and changes without having access to systemwide features. This person does not have to be familiar with Cisco IOS software.

•

Phone user—Able to program a small set of features on his or her own phone and search the Cisco Unified CME directory.

The Cisco Unified CME GUI uses HTTP to transfer information between the Cisco Unified CME router and the PC of an administrator or phone user. The router must be configured as an HTTP server, and an initial system administrator username and password must be defined. Additional customer administrators and phone users can be added by using Cisco IOS command line interface or by using GUI screens.

Cisco Unified CME provides support for eXtensible Markup Language (XML) cascading style sheets (files with a .css suffix) that can be used to customize the browser GUI display.

The GUI supports authentication, authorization, and accounting (AAA) authentication for system administrators through a remote server capability. If authentication through the server fails, the local router is searched.

Cisco Unified CME GUI must be installed and set up before it can be used. Instructions for using the Cisco Unified GUI are in online help for the GUI.

How to Install Cisco Voice Services Hardware

Note Cisco routers are normally shipped with Cisco voice services hardware and other optional equipment that you ordered already installed. In the event that the hardware is not installed or you are upgrading your existing Cisco router to support Cisco Unified CME or Cisco Unity Express, you will be required to install hardware components.

Voice bundles do not include all the necessary components for Cisco Unity Express. Contact the Cisco IP Communications Express partner in your area for more information about including Cisco Unity Express in your configuration.

Prerequisites

•

Cisco router and all recommended hardware for Cisco Unified CME, and if required, Cisco Unity Express, is ordered and delivered, or is already onsite. To determine the recommended hardware configuration to support your telephony system requirements, see the Cisco IPC Express Quote-Builder online tool.

Installing Hardware

To install the Cisco router and voice services hardware, perform the following steps.

SUMMARY STEPS

Use the show version or show flash command to check the amount of memory installed in the router.

Disable Smartinit and allocate ten percent of the total memory to Input/Output (I/O) memory.

DETAILED STEPS

Step 1

Install the Cisco router on your network. To find installation instructions for the Cisco router, access documents located at www.cisco.com>Technical Support & Documentation>Product Support>Routers>router you are using>Install and Upgrade Guides.

To find installation instructions for any Cisco interface card, access documents located at www.cisco.com>Technical Support & Documentation>Product Support>Cisco Interfaces and Modules>interface you are using>Install and Upgrade Guides or Documentation Roadmap.

To find installation instructions for any Cisco EtherSwitch module, access documents located at www.cisco.com>Technical Support & Documentation>Product Support>Cisco Switches>switch you are using>Install and Upgrade Guides.

Step 3

Connect to the Cisco router using a terminal or PC with terminal emulation.

Attach a terminal or PC running terminal emulation to the console port of the router. For more information on cabling, and details about how to connect a terminal to the console port or the AUX port, see Cabling Guide for Console and Aux Ports on Cisco Routers.

Note Memory recommendations and maximum numbers of Cisco IP phones identified in the next step are for common Cisco Unified CME configurations only. Systems with large numbers of phones and complex configurations may not work on all platforms and can require additional memory or a higher performance platform.

Step 4

Log in to the router and use the show version EXEC command or the show flash privileged EXEC command to check the amount of memory installed in the router. Look for the following lines after issuing the show version command.

The first line indicates how much Dynamic RAM (DRAM) and Packet memory is installed in your router. Some platforms use a fraction of their DRAM as Packet memory. The memory requirements take this into account, so you have to add both numbers to find the amount of DRAM available on your router (from a memory requirement point of view).

Look for the following line after issuing the show flash command. Add the number available to the number used to determine the total flash memory installed in the Cisco router.

Step 6

Compare the amount of memory required to the amount of memory installed in the router. To install or upgrade the system memory in the router, access documents located at www.cisco.com>Technical Support & Documentation>Product Support>Routers>router you are using>Install and Upgrade Guides.

Step 7

Use the memory-size iomem i/o memory-percentage privileged EXEC command to disable Smartinit and allocate ten percent of the total memory to Input/Output (I/O) memory.

How to Install Cisco IOS Software

Note The Cisco router in a voice bundle is preloaded with the recommended Cisco IOS software release and feature set plus the necessary Cisco Unified CME phone firmware and GUI files to support Cisco Unified CME and Cisco Unity Express. If the recommended software is not installed or if you are upgrading an existing Cisco router to support Cisco Unified CME and Cisco Unity Express, you will be required to download and extract the required image and files.

Prerequisites

•

The Cisco router is installed including sufficient memory, all Cisco voice services hardware, and other optional hardware.

Installing Cisco IOS Software

To verify that the recommended software is installed on the Cisco router and if required, download and install a Cisco IOS Voice or higher image, perform the following steps.

SUMMARY STEPS

Determine whether the Cisco IOS release supports the recommended Cisco Unified CME.

Download and extract the recommended Cisco IOS IP Voice or higher image to flash memory

Use the reload command to reload the Cisco Unified CME router with the new software.

DETAILED STEPS

Step 1

Identify which Cisco IOS software release is installed on router. Log in to the router and use the show version EXEC command.

Step 2

Compare the Cisco IOS release installed on the Cisco router to the information in the Cisco Unified CME and Cisco IOS Version Matrix to determine whether the Cisco IOS release supports the recommended Cisco Unified CME.

To find software installation information, access information located at www.cisco.com>Technical Support & Documentation>Product Support> Cisco IOS Software>Cisco IOS Software Mainline release you are using> Configuration Guides> Cisco IOS Configuration Fundamentals and Network Management Configuration Guide>Part 2: File Management>Locating and Maintaining System Images.

Step 4

Using Cisco Unified Communications Express - QCT to Generate a Telephony Configuration

To u se Cisco Unified Communications Express - QCT to generate a basic telephony configuration for a PBX or Square Mode (key system) system, with or without Cisco Unity Express, or to reset the configuration of a Cisco router to factory default, see the Cisco Unified Communications Express - QCT User Guide.

Prerequisites

•

A PC with Microsoft� Internet Explorer 5.5 or a later version is connected, using a serial cable, to the console port of Cisco router to be configured. If you need assistance in connecting your PC to your router's console port, refer to the Install and Upgrade Guide for the Cisco router.

•

The Block Pop-up Windows feature for Microsoft� Internet Explorer must be disabled.

•

You must be a member of Administrators group under User Account settings for your PC.

•

The factory-default configuration is loaded in nonvolatile memory and in the running configuration of the Cisco router to be configured.

Note Cisco Unified Communications Express - QCT can be used to restore the factory default configuration on router to be configured.

•

If you are using Cisco Unified Communications Express - QCT to upload firmware files for Cisco Unified IP phones after uploading the generated configuration, all Cisco firmware files to be uploaded must be installed in the folder named Phoneloads, within the local folder in which Cisco Unified Communications Express - QCT is installed.

Restrictions

•

Cisco Unified Communications Express - QCT cannot be used to perform routine additions and changes associated with employee turnover.

•

Cisco Unified Communications Express - QCT can configure only a subset of features of Cisco Unified CME and generate the basic telephony configuration.

What to Do Next

After using Cisco Unified Communications Express - QCT to generate a basic telephony configuration, you can skip the following modules in the Cisco Unified CME System Administrator Guide when you use Cisco IOS commands to add features to the initial configuration:

•

Configuring Voice-Mail Support (for Cisco Unity Express only). To add support Cisco Unity or other voice-mail systems, you must use Cisco IOS commands to modify the configuration.

Using Cisco Unified CME GUI to Modify or Maintain Configuration

Prerequisites

•

Cisco Unified CME GUI must be enabled. For information, see "Enabling the GUI".

Restrictions

•

The web browser that you use to access the GUI must be Microsoft Internet Explorer 5.5 or a later version. No other type of browser can be used to access the GUI.

•

Cannot provision voice features such as digit translation, call routing, and class of restriction.

•

Can only provision IP phones that are registered to Cisco Unified CME. Cannot use bulk administration to import multiple phones at the same time. Cannot manage IP phone firmware.

•

Requires manual upgrade of files in flash memory of router if Cisco Unified CME is upgraded to later version.

–

If you use an XML configuration file to create a customer administrator login, the size of that XML file must be 4000 bytes or smaller.

–

The password of the system administrator cannot be changed through the GUI. Only the password of a customer administrator or a phone user can be changed through the GUI.

–

If more than 100 phones are configured, choosing to display all phones will result in a long delay before results are shown.
