C H A P T E R 2 Preparing to Install the Cisco Unified IP Phone on Your Network Cisco Unified IP Phones enable you to communicate using voice over a data network. To provide this capability, the Cisco Unified IP Phones depend upon and interact with several other key Cisco Unified Communications Products, including Cisco Unified CallManager.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Understanding Interactions with Other Cisco Unified Communications Products Understanding Interactions with Other Cisco Unified Communications Products To function in the IP telephony network, the Cisco Unified IP Phone must be connected to a networking device, such as a Cisco Catalyst switch. You must also register the Cisco Unified IP Phone with a Cisco Unified CallManager system before sending and receiving calls.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Understanding Interactions with Other Cisco Unified Communications Products Understanding How the Cisco Unified IP Phone Interacts with the Cisco Catalyst Family of Switches The Cisco Unified IP Phone 7912G has an internal Ethernet switch, enabling it to switch incoming traffic to the phone, to the access port, or to the network port. The Cisco Unified IP Phone 7905G do not include an internal Ethernet switch or an access port.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Understanding the Phone Startup Process Understanding the Phone Startup Process When connecting to the VoIP network, the Cisco Unified IP Phone goes through a standard startup process composed of the steps described in Table 2-1. Depending on your specific network configuration, not all of these steps may occur on your Cisco Unified IP Phone. Table 2-1 Cisco Unified IP Phone Startup Process Step Configuration 1.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Understanding the Phone Startup Process Table 2-1 Cisco Unified IP Phone Startup Process (continued) Step Configuration 3. Configuring VLAN If the Cisco Unified IP Phone is connected to a Cisco Catalyst switch, the switch next informs the phone of the voice VLAN defined on the switch. The phone needs to know its VLAN membership before it can proceed with the Dynamic Host Configuration Protocol (DHCP) request for an IP address.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Understanding the Phone Startup Process Table 2-1 Cisco Unified IP Phone Startup Process (continued) Step Configuration 5. Accessing a TFTP Server In addition to assigning an IP address, the DHCP server directs the Cisco Unified IP Phone to a TFTP Server. If the phone has a statically defined IP address, you must configure the TFTP server locally on the phone; the phone then contacts the TFTP server directly.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Understanding the Phone Startup Process Table 2-1 Cisco Unified IP Phone Startup Process (continued) Step Configuration 6. Requesting the Configuration File and the Profile File The TFTP server has configuration files and profile files. A configuration file includes parameters for connecting to Cisco Unified CallManager and information about which image load a phone should be running.
Chapter 2 Understanding Phone Configuration Files and Profile Files Preparing to Install the Cisco Unified IP Phone on Your Network Understanding Phone Configuration Files and Profile Files Configuration files for a phone are stored on the TFTP server and define parameters for connecting to Cisco Unified CallManager. In general, any time you make a change in Cisco Unified CallManager that requires the phone to be reset, a change is made to the phone’s configuration file automatically.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Providing Power to the Cisco Unified IP Phone Providing Power to the Cisco Unified IP Phone You can power a Cisco Unified IP Phone by the following sources: • External power—optional Cisco AC adapter and power cord for connecting to a standard wall receptacle. • Inline power—inline power provider to the Cisco Unified IP Phone when connected to a Cisco Catalyst switch capable of providing inline power.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Providing Power to the Cisco Unified IP Phone • Power Source Design, page 2-10 • Redundancy Feature, page 2-11 • Installing the Cisco Unified IP Phone, page 3-6 Power Outage Your accessibility to emergency service through the phone is dependent on the phone being powered. If there is an interruption in the power supply, Service and Emergency Calling Service dialing will not function until power is restored.

Chapter 2 Determining the MAC Address of a Cisco Unified IP Phone Preparing to Install the Cisco Unified IP Phone on Your Network Determining the MAC Address of a Cisco Unified IP Phone There are several procedures that require you to determine and enter the MAC address of a Cisco Unified IP Phone. These procedures include adding phones the the Cisco Unified CallManager database using Cisco Unified CallManager Administration or using BAT.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Adding Phones to the Cisco Unified CallManager Database Table 2-3 provides an overview of these methods for adding phones to the Cisco Unified CallManager database.
Chapter 2 Adding Phones to the Cisco Unified CallManager Database Preparing to Install the Cisco Unified IP Phone on Your Network You can use auto-registration to quickly enter phones into the Cisco Unified CallManager database. You can then modify any settings, such as the directory numbers, from Cisco Unified CallManager. Additionally, you can move auto-registered phones to new locations and assign them to different device pools without affecting their directory numbers.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Creating a SIP Profile Adding Phones with BAT The Cisco Unified Bulk Administration Tool (BAT) is a plug-in application for Cisco Unified CallManager that enables you to perform batch operations, including registration, on multiple phones. To add phones using BAT only (not in conjunction with TAPS), you first need to obtain the appropriate MAC address for each phone.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Creating a SIP Profile Step 4 Note 2-16 Click Save. You must assign a SIP profile to each phone after you have configured and named your SIP profiles. Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Using Cisco Unified IP Phones with Different Protocols To select the applicable device profile, follow these steps: Procedure Step 1 From Cisco Unified CallManager Administration, navigate to Device > Phone. Step 2 Click on the name of the phone you are configuring to bring up the Phone Configuration screen.
Chapter 2 Using Cisco Unified IP Phones with Different Protocols Preparing to Install the Cisco Unified IP Phone on Your Network Converting a New Phone from SCCP to SIP A new, unused phone is set for SCCP by default. To convert this phone to SIP, perform these steps: Procedure Step 1 Take one of these actions: • To auto-register the phone, set the Auto Registration Phone Protocol parameter in Cisco Unified CallManager Administration to SIP.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Using Cisco Unified IP Phones with Different Protocols Converting an In-Use Phone from SIP to SCCP To convert a phone that is in use in your network from SIP to SCCP, perform these steps. For more information, Cisco Unified CallManager Administration Guide. Procedure Step 1 In Cisco Unified CallManager Administration, delete the existing SIP phone from the Cisco Unified CallManager database.
