Configuring IP Phones and Extensions

Table of contents:

The features and configuration discussed thus far can be configured only via the router CLI because they cannot be accessed through the GUI. Cisco CME IP phones and extensions (lines) are the first features available using the GUI. After you successfully log into the Cisco CME GUI (as covered in Chapter 13), you might add, change, and remove ephone-dns, ephones, and speed-dial lists and perform other configuration tasks.


Not all the Cisco CME features can be configured via the GUI. Some features might require router configuration (CLI), and others might depend on the privilege level granted with your login.

The following sections provide some highlights of the GUI configuration:

  • Adding an extension
  • Adding a phone
  • Assigning an extension to a phone
  • Changing or deleting an extension
  • Changing or deleting a phone

For configuration details on more GUI features, choose Help > Configuration to launch the online GUI help, or access the Cisco CME and Cisco UE Administration Guides on

Adding an Extension

An extension in the GUI maps to an ephone-dn in the router CLI. It is best to add the extensions before configuring the phones, because the phone's buttons have extensions assigned to them. Therefore, you can't complete the phone configuration until the extensions have been defined.

To add an extension to your system, choose Configure > Extensions and then click Add, as shown in Figure 14-2.

Figure 14-2. Adding an Extension

The system automatically assigns the Sequence Number field and maps to the ephone-dn number in the router configuration.

Adding a Phone

A phone in the GUI maps to an ephone in the router CLI. To see a list of the phones on your system, choose Configure > Phones. Cisco CME automatically detects the MAC address and type of phones connected to your router and assigns a phone sequence number to each (the ephone x configuration in the router CLI). With the GUI you cannot manually enter a MAC address for a phone that is not registered with the Cisco CME router. The phone must register first, and then its MAC address automatically shows up in the GUI for selection. Chapter 16, "Troubleshooting Basic Cisco IPC Express Features," discusses troubleshooting phone registrations. If your phones' MAC addresses do not show up in the GUI because they do not register with Cisco CME, follow the troubleshooting steps described in Chapter 16 to correct this.

To add an IP phone on your system, follow these steps:


Select Add a phone from the Configure > Phones menu.


Select the phone's MAC address from the Phone Physical ID drop-down list, as shown in Figure 14-3.

Figure 14-3. Adding a Phone


For testing or lab purposes, you can enter fictitious MAC addresses into the configuration for phones that do not exist. This might be useful if you want to preconfigure the system, and you do not have the phones with you (but you know the MAC addresses). Or perhaps you want to set up a lab configuration for training or experimentation purposes, and you want to enter more phones into the configuration than are physically available in your lab.

You can enter an ephone definition into the router CLI configuration with a fictitious MAC address, as shown in Example 14-1. The MAC address 0002.FFFF.1040 does not belong to any real phone; it was simply entered as a string of characters into the CLI prompt. If you then log into the GUI (or refresh the page if you are already logged in), this new phone shows up on the Configure > Phones menu.

Example 14-1. Entering a Nonexistent Phone into the Configuration

Router#show running-config
ephone 40
 username "User40"
 mac-address 0002.FFFF.1040 


Assigning an Extension to a Phone

Extensions appear on the buttons of an IP phone. To add an extension to a phone, follow these steps:

Step 1.

Select a phone from the Configure > Phones menu by clicking its MAC address. The Change Phone window appears, as shown in Figure 14-4.

Figure 14-4. Change Phone Window


Step 2.

In the phone line buttons layout, select the button to which you want to add the extension. The Button window pops up, as shown in Figure 14-5 (button 2 is selected).

Step 3.

Select an extension from the list to add it to the button on the phone. You might also select a ring type for this extension from the Ring Type/Mode drop-down list. Click Save to save the change.

Changing or Deleting an Extension

To change or delete an extension, follow the same steps as given previously for adding an extension to a phone. In the Change Phone window, instead of selecting a button with no extension assigned, as you did to add an extension, you select a button with the extension to change or delete. In the subsequent Button window, you can select a new extension (to change it) or deselect the existing assigned extension (to delete it).

Changing or Deleting a Phone

To change a phone, select the MAC address from the Configure > Phones menu, and change the desired parameters in the subsequent windows.

To delete a phone, select the phone(s) to delete from the Configure > Phones menu, and click Delete at the top of the screen.
