Initializing Cisco Unified IP Phones

Highlight and configure each of the following parameters:

Step 6

•

Step 7

Press the Save softkey.

The phone programs the new information into flash memory and resets.

Setting and Restoring Phone-Specific Parameters

Phone users can modify the phone-specific configuration settings using the phone menus. If a

phone-specific configuration file exists, the phone uses locally configured parameters until the next

reboot. If a phone-specific configuration file does not exist, you must configure the phone locally with

parameters specific to that phone.

•

Prerequisites

•

To set phone-specific parameters, follow these steps:

Procedure

Unlock the phone.

Step 1

See

Step 2

Select Settings > SIP Configuration.

The SIP Configuration menu appears.

Step 3

Set the required parameters.

OL-7890-01

IP Address—IP address of the phone.

Subnet Mask—IP subnet mask used by the phone.

TFTP Server—IP address of the TFTP server from which the phone downloads its configuration

files and firmware images.

Default routers 1 through 5—IP address of the default gateway used by the phone. Default routers

2 through 5 are the IP addresses of the gateways that the phone attempts to use as an alternate

gateway if the primary gateway is not available.

Domain Name—Name of the DNS domain in which the phone resides.

DNS servers 1 through 5—IP address of the DNS server used by the phone to resolve names to IP

addresses. The phone attempts to use DNS servers 2 through 5 if DNS server 1 is unavailable.

To configure the preferred codec and out-of-band DTMF parameters, press Change until the option

appears, then press Save.

If your system has been set up to have the phones retrieve the configuration file from a TFTP server,

you must use the server's configuration file to change the parameter value to a null value (" ") or to

"UNPROVISIONED." The phone uses the setting for that variable that it has stored in flash memory.

If the telnet_level parameter is set to allow privileged commands to be executed, the entire SIP

configuration can be erased. Use the erase_protflash command so that the phone can retrieve its

configuration files.

Define the line parameters (those identified as linex) on the phone. If you configure a line to use an

e-mail address, that line can be called only by using an e-mail address. Similarly, if you configure a

line to use a number, that line can be called only by using the number.
