4 LAB OVERVIEW: In the lab documents, xx refers to your Pod number. For example, if you are seated at POD01, you would replace all instances of xx in the lab documents with 01. Several of the labs will require you to partner with another pod to demonstrate certain features of the system. We have pre-wired the hardware to your buddy pod. This is to emulate a PSTN connection for the lab environment. Normally, you would plug trunks from the PSTN into the FXO ports and analog devices (such as fax machines) into the FXS ports. Please be sure and coordinate with the team seated at your buddy pod so that you are both working on roughly the same portion of a lab and can complete the verification steps successfully. All of the software needed to complete the lab has been installed on the virtual workstations. This software includes the Cisco Configuration Assistant (CCA), Cisco IP Communicator (CIPC), and the new auto attendant (AA) script. Unless otherwise noted, it is necessary to restore the UC500 to factory default condition after each lab section. Instructions for how to do this are included in Appendix A. Please read items in RED very closely.

5 LAB1: PLUG & PLAY - Note: This lab has been done for you and is provided for reference and future hands on installations. Introduction: The UC520 is a voice appliance that is designed with the ease of deployment as a primary focus. To facilitate this, the IOS detects the equipments plugged in the Power over Ethernet (PoE) ports and accordingly configures the system. For instance, if a 7960G phone is plugged in, the IOS detects the type of the phone and auto configures the ephone with type and button. Objective: The objective of the PLUG & PLAY lab is to show the ease of install for the UC520 system. At the completion of this lab, all IP phones (including the CIPC softphone) and analog phones on the UC520 should get dial tone and be able to call each other. You should be able to call out as well if a PSTN connection is available via a FXO or BRI lines. Topology: Use the following topology UC520 Setup steps: 1. Be sure your UC500 system is powered up and plug one of the broadband internet [long red] cables into the WAN port. 2. Plug in the 7970 and 7961 phones with short red cables to the UC520 Power Over Ethernet (POE) ports at each POD 3. Connect your laptop to the back of an IP phone or to a POE port on the UC500. Verify that you get an IP address assigned to the laptop. 4. Install and launch Cisco IP Communicator (CIPC) SoftPhone on your laptop. a. After launching CIPC, a Preferences Screen will appear (Right click on the CIPC to view preferences if it does not appear). Now configure specific TFTP server on the network tab as the UC520 IP address ( ). Page 5 of 74

6 Verify steps: 1. Ensure that all the phones register to the UC520 and receive an extension. Verify the extensions as 201, 202 and 203 (CIPC) 2. Place a call between 201 & 202 answer the call, place on HOLD and check if the Music on Hold (MOH) works. 3. Place a call between 201 and CIPC (x203). Answer the call and place on hold on the IP Communicator and note that the music plays to the IP phone. Take the call off hold and place it on hold on the IP phone. Note that the IP Communicator only hears a hold tone and not the MoH source. It is NOT necessary to restore the system to factory defaults at the end of this lab. NOTE: Before making any changes in CCA, ensure that the Apply and Refresh buttons at the bottom of the screen are active. These are grayed out while CCA reads the configuration from the UC500. LAB2: KEY SYSTEM w/ VOIC Introduction: The UC520 supports two voice system configuration types PBX type and Key system type. LAB2 focuses on the Key System configuration. Typical Key Systems consist of one or more lines coming from the PSTN (e.g. Analog FXO trunks) that ring a group of selected phones. To make outbound calls, IP Phone users select one of the buttons on their IP Phones that correspond to the lines from the PSTN. In addition to the PSTN lines, users have internal extensions with voic . Objective: The main objective of this lab is to configure the basic Key System with voic features. This is configured using the Cisco Configuration Assistant (CCA). At the completion of this lab, the system will be setup as a Key System with extensions of all users, voic boxes, intercom, paging and power failover configuration. Reference: Video Demo for CCA: Page 6 of 74

Page 18 of 74

19 Verify Steps: 1. Check the FirstName and LastName on the IP Phones. Place a call from x202 to x203, do not answer the call and ensure that call rolls over to VM. 2. Verify that the Message Waiting (MWI) light turns on for x203. Press the Messages button on x203 and enroll the user in voic . Use 789 as a password. After enrollment is complete, check the message left by x Test Intercom by pressing the intercom button on CIPC x Dial the paging extension 101 from x202 to test the Paging feature. 5. For steps 5 & 6, you need to work with your partner POD. Connect an analog cable from FXO port 0/1/0 (on your POD), to the FXS port 0/0/3 (on the partner s POD). Configure the CFNA timer on the analog FXS ports to 20 seconds. Run the test below and then reverse the ports between the two PODs. a. Call from an IP Phone on your POD by selecting CO Line 1 button you should get dial tone go ahead and dial 202 and it should ring the appropriate phone on the buddy POD. b. From the partner s POD call x304 this should ring x201 on your POD. b NOTE: You may run into an issue with calls disconnecting as soon as they are answered. You will not run into this issue in field. This is only observed on back-to-back (FXS-FXO) UC500 setup. If so, contact your proctor and have him/her configure no battery-reversal on FXS ports. NOTE: When both you and your buddy pod have completed this lab, please reset UC500 and CUE to factory default setting using the procedure in Appendix A! Also, make sure you close CIPC. Page 19 of 74

20 LAB3: PBX, VOIC & AUTO ATTENDANT Introduction: The UC520 supports two voice system configuration types PBX type and Key-system type. LAB3 focuses on the PBX system configuration. A typical PBX system involves an Auto Attendant that handles incoming calls from a PSTN line (e.g. Analog FXO trunks) and transfers the caller to one of the internal extensions. Outbound local/ld/international calls are routed out through the PSTN line. In addition to this, local extensions have voic boxes where callers can leave messages. Objective: The main objective of this lab is to configure the basic PBX system, voic and Auto Attendant features. These features will be configured using Cisco Configuration Assistant (CCA). After completion of this lab, you will be able to setup the SBCS system as a PBX, place calls between extensions, and configure a SIP Trunk on the UC520 to a Service Provider (Lab Simulation), and place calls in & out to the PSTN via the SIP trunk. Due to the virtual nature of this lab, although you will configure the SIP trunk, you will not be able to test the SIP functionality. Topology: UC520 SIP Trunk Service Provider WAN PSTN CCA Setup steps: Launch CIPC on both workstations and use the CIPC that displays x203 for the remainder of the lab. Launch Cisco Configuration Assistant, connect to the created community and enter the username and password (cisco/cisco), let it discover the network and connected devices. 1. Click on Configure -> Telephony -> Voice on the left navigation bar or click on the Phone icon on the top menu bar. Wait until the Refresh and Apply buttons are enabled before making any changes. In this lab,, we will configure the various tabs - Device, System, Dial plan, AA & Voic , SIP Trunking Voice Features, and Users. 2. Click on the Device tab & select the System Type as a PBX.
