Caution Means reader be careful. In this situation, you might do something that could result in equipment damage or loss of data.
Tip Means the following information will help you solve a problem. The tips information might not be troubleshooting or even an action, but could be useful information, similar to a Timesaver.
Accessibility
You can configure the Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways by using the Cisco command-line interface (CLI). The CLI conforms to code 508 because it is text based and relies on a keyboard for navigation. You can configure and monitor all functions of the voice gateway through the CLI.
For a complete list of guidelines and Cisco products’ adherence to accessibility, see Cisco Accessibility Products at the following URL:

About the Voice Gateways
Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways deliver analog voice gateways for the service provider as well as commercial and enterprise unified communication markets. These voice gateways provide voice connectivity to devices such as analog phones, fax machines, and modems.
Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways provide support for 2-FXS (Cisco VG202 and Cisco VG202XM) and 4-FXS (Cisco VG204 and Cisco VG204XM) ports, each supporting independent telephone numbers giving you two or four separate lines, and parity with Cisco IOS fax/modem, security, and Session Initiation Protocol (SIP) features. Both voice gateways are configurable with Cisco Unified Communications Manager (CUCM) & Cisco Unified Communications Manager Express (CUCME).
Note Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways are fixed voice gateways and do not support interface cards.
Port Numbering Conventions
The Cisco VG202 voice gateway supports two RJ-11 ports and supports two FXS voice ports with two 10/100 Fast Ethernet ports. Figure 1-1 shows the interfaces and ports on the Cisco VG202 voice gateway. All interface ports are on the back of the chassis.

Cisco VG204XM voice gateways are as follows:
•Foreign Exchange Station (FXS) voice port numbering begins at 0/0 and extends to 0/1 for the Cisco VG202 and Cisco VG202XM, and extends to 0/3for the Cisco VG204 and Cisco VG204XM.
•10/100BASE-T Fast Ethernet ports are numbered Fast Ethernet 0/0 and Fast Ethernet 0/1, from right to left.

About Cisco IOS Software
|
|
Understanding these concepts about the Cisco IOS software will save time as you begin to use the CLI. |
|
|
If you have never used Cisco IOS software or if you need a refresher, take a few minutes to read this |
|
|
chapter before you proceed to the next chapter. |
|
|
If you are already familiar with Cisco IOS software, proceed to Chapter 2, “Configuring Your Voice |
|
|
Gateway Using the setup Command.” |
|
|
For a comprehensive view of Cisco IOS configuration fundamentals, see the Cisco IOS Configuration |
|
|
Fundamentals Configuration Guide, Release 12.4. |
|
|
|
Note |
• Your Cisco IOS software release may not support all of the features documented in this document. |
|
|
|
For the latest feature information and caveats, see the release notes for your platform and software |
|
|
release. |
|
|
• Use the Cisco Feature Navigator to find information about platform support and Cisco IOS and |
|
|
Catalyst OS software image support. To access the Cisco Feature Navigator, go to |

Chapter 1 Understanding Interface Numbering and Cisco IOS Software Basics
Understanding Cisco IOS Software Basics
•The VG202 and VG204 devices support IOS software releases 15.0(1)M or earlier* due to memory limitations. The VG202XM and VG204XM devices will support the latest IOS software release 15.3(2)T and beyond. Earlier releases are not supported on the VG202XM and VG204XM. *Deployments requiring support for secure SCCP based call control are supported using 15.1(4)M IOS release.
Getting Help
Use the question mark (?) and arrow keys to help you enter commands:
• For a list of available commands, enter a question mark:
VG> ?
• To complete a command, enter a few known characters followed by a question mark (with no space):
VG> s?
• For a list of command variables, enter the command followed by a space and a question mark:
VG> show ?
•To redisplay a command you previously entered, press the up arrow key. You can continue to press the up arrow key for more commands.
Command Modes
The Cisco IOS user interface involves different modes. Each command mode permits you to configure different components on your voice gateway. The commands available at any given time depend on which mode you are currently in. Entering a question mark (?) at the prompt displays a list of commands available for each command mode. Table 1-1 lists the most common command modes.

Timesaver Each command mode restricts you to a subset of commands. If you are having trouble entering a command, check the prompt, and enter the question mark (?) for a list of available commands. You might be in the wrong command mode or using the wrong syntax.
In the following example, notice how the prompt changes after each command to indicate a new command mode:
VG> enable
Password: <enable password>
VG# configure terminal
VG(config)# interface fastEthernet 0/0
VG(config-if)# line 0 VG(config)# exit
VG#
%SYS-5-CONFIG_I: Configured from console by console
The last message is normal and does not indicate an error. Press Return to get the VG# prompt.
Note You can press Ctrl-Z in any mode to immediately return to enable mode (VG#), instead of entering exit, which returns you to the previous mode.
Undoing a Command or Feature
If you want to undo a command you entered or disable a feature, enter the keyword no before most commands; for example, no ip routing.
Saving Configuration Changes
You need to enter the copy running-config startup-config command to save your configuration changes to NVRAM, so the changes are not lost if there is a system reload or power outage. For example:
VG# copy running-config startup-config

Where to Go Next
Now that you have learned some Cisco IOS software basics and seen a typical deployment scenario, you can begin to configure your voice gateway by using the CLI.
Remember that:
•You can use the question mark (?) and arrow keys to help you enter commands.
•Each command mode restricts you to a set of commands. If you have difficulty entering a command, check the prompt and then enter the question mark (?) for a list of available commands. You might be in the wrong command mode or be using the wrong syntax.
