Cisco IPC Express System Configuration Example

This chapter covers the following topics:

• Configuring a two-site sample Cisco IP Communications (IPC) Express system
• Planning and offline staging
• Basic router setup
• Initial Cisco CallManager Express (CME) system setup
• Configuring extensions and phones
• Configuring the Public Switched Telephone Network (PSTN) interface
• Configuring Cisco Unity Express (UE) automated attendant (AA) and voice mail
• Configuring Cisco CME call processing features
• Interconnecting multiple Cisco IPC Express systems
• Listing of the Site A and Site B Cisco CME and Cisco UE configurations built in this chapter

This chapter provides a step-by-step configuration guide to help you set up your Cisco IP Communications (IPC) Express system. System configuration and setup topics, features, and details were discussed in depth in Chapter 13, "Cisco IPC Express General Administration and Initial System Setup," and Chapter 14, "Configuring and Managing Cisco IPC Express Systems." This chapter helps you understand that information by walking you through configuring a newly ordered system to create a working system for your office. Not every feature is covered again in this chapter. Instead, it focuses on the steps you should follow and draws on the previous chapters for many of the details.

This chapter uses a two-site sample network, as shown in Figure 15-1. This chapter walks through the setup and configuration of Site A, the primary site. Site B has a very similar basic configuration and is used to illustrate what extra configuration to do (as soon as you have the standalone system running with Site A) to connect two Cisco IPC Express sites.

Site A uses the following hardware components:

• PSTNVWIC-2MFT-T1 and AIM-ATM-VOICE-30 (WIC slot 0)
• RouterCisco 3725 router
• NM-CUECisco UE R2.0 (NM Slot 1)
• PSTN interfaceNM-HD-2V and VIC2-2FXO (NM slot 2)
• IOS imageCisco IOS Release 12.3(11)T2 IP Voice
• IP phonesTwo real Cisco 7960 IP Phones and three virtual phones

Site B uses the following hardware components:

• RouterCisco 2691 router
• NM-CUECisco UE R2.0 (slot 1)
• IOS imageCisco IOS Release 12.3(11)T2 IP Voice
• IP phonesTwo real Cisco 7960 IP Phones and three virtual phones

Site A's numbering plan starts with two, and Site B's extensions start with three. Both sites use a four-digit extension numbering plan.

The next sections work through the following steps for configuring a Cisco IPC Express system:

Step 1.	Planning and offline staging
Step 2.	Basic router setup
Step 3.	Initial Cisco CME system setup
Step 4.	Configuring extensions and phones
Step 5.	Configuring the PSTN interface
Step 6.	Configuring Cisco UE AA and voice mail
Step 7.	Configuring Cisco CME call processing features
Step 8.	Interconnecting multiple Cisco IPC Express systems

The last part of this chapter, "Sample System Configurations," provides the full configurations of Sites A and B built during these steps.
