Configuring the Voice Interface
Whenever you install a new interface or want to change the configuration of an existing interface, you
must configure the interface. If you replace a module that was already configured, the Cisco IAD
recognizes it and brings up the interface in the existing configuration.
The Cisco IAD2435 router is a fixed-configuration router and does not support interface cards.
Note
Before you configure an interface, have the following information available:
•

Timesaver Obtain this information from your system administrator or network plan before you begin configuring
your Cisco IAD.
To configure a voice interface, you must use configuration mode (manual configuration). In this mode,
you can enter Cisco IOS commands through the command-line interface (CLI).
Before you begin, disconnect all WAN cables from the Cisco IAD to prevent it from running the
AutoInstall process. The Cisco IAD tries to run AutoInstall whenever you power it on if there is a WAN
connection on both ends and the Cisco IAD 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 Cisco IAD to determine
that AutoInstall is not connected to a remote TCP/IP host.
To configure the voice interface configuration mode, follow these steps:
Connect a console to the Cisco IAD. If you need instructions for connecting a console, see the
