Configuring The Voice Interface - Cisco 2620 Configuration Manual

Configuring the Voice Interface

Whenever you install a new interface, or if you want to change the configuration of an existing interface,
you must configure the interface. If you replace a module that was already configured, the router
recognizes it and brings up the interface in the existing configuration.
Before you configure an interface, have the following information available:
•
•
Timesaver
Obtain this information from your system administrator or network plan before you begin router
configuration.
To configure a voice interface, you must use configuration mode (manual configuration). In this mode,
you can enter Cisco IOS commands at the router prompt.
Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall
process. The router tries to run AutoInstall whenever you power it on if there is a WAN connection on
both ends, and the router does not have a valid configuration file stored in NVRAM (for instance, when
you add a new interface). It can take several minutes for the router to determine that AutoInstall is not
connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.
To configure the voice interface configuration mode, follow this procedure:
Step 1
Connect a console to the router. If you need instructions for connecting a console, refer to the installation
chapter of your router installation and configuration guide.
Step 2
Power onthe router. If the current configuration is no longer valid, after about one minute you see the
following prompt:
Would you like to enter the initial dialog? [yes/no]:

Configuration changes can be made only in enable mode. The prompt changes to the privileged EXEC
(enable) prompt (

Step 4
Enter the configure terminal command to enter configuration mode:
Router# configure terminal
Router(config)#
The router enters global configuration mode, indicated by the
Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers
