Chapter 4 Configuring Voice over IP
Configuring the Voice Interface
• Implement a dial plan, including the following tasks:
– Complete your company’s dial plan. That is, decide what patterns of dialed numbers will access
what telephony endpoints.
– Establish a working telephony network based on your company’s dial plan.
– Integrate your dial plan and telephony network into your existing IP network topology.
Note To support FXO signaling, you must install a VIC2-4FXO interface card. For information on
connecting voice interface cards (VICs), see “Connecting Voice Network Modules” at the
following URL:

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.
Note The Cisco IAD2435 router is a fixed-configuration router and does not support interface cards.
Before you configure an interface, have the following information available:
• Protocols you plan to route on the new interface
• IP addresses, subnet masks, network numbers, zones, or other information related to the routing
protocol
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:
Step 1 Connect a console to the Cisco IAD. If you need instructions for connecting a console, see the
installation chapter of your Cisco IAD installation and configuration guide.
Step 2 Power on the Cisco IAD. If the current configuration is no longer valid, after about one minute you see
the following prompt:
