Chapter 2 Preparing to Install the Cisco IP Phone on Your Network

Adding Phones to the Cisco CallManager Database

Adding Phones Manually

If you want to assign specific directory numbers to a specific Cisco IP Phone without using auto-registration, you can manually add each phone to the Cisco CallManager database or use the Bulk Administration Tool (BAT).

If you want to add phones manually, and are not using Dynamic Host Configuration Protocol (DHCP) in your network, then you must configure the IP settings and Trivial File Transfer Protocol (TFTP) server locally on each phone.

Alternatively, if you use DHCP, but want to manually set the TFTP server, then allow the phone to start up, using DHCP, before re-assigning the TFTP server.

See these topics for more information:

Adding Phones Manually Using DHCP

If you are using DHCP in your network, but you are not using auto-registration, you can manually add a phone to the Cisco CallManager database. If you are using DHCP, you do not need to assign IP addresses or TFTP servers.

Procedure

Step 1 Log in to the Cisco CallManager Administration application.

Step 2 From the menu bar, choose Device > Add a New Device.

The Add a New Device window appears.

Step 3 Select Phone from the Device Type drop-down menu and click Next.

The Add a New Phone window appears.

Step 4 Select a phone type from the drop-down menu and click Next.

The Phone Configuration window appears. The fields displayed in this window depend upon the phone type selected.
