Change the IP address on your phone

As your network settings require, you may need to change or manually assign the IP address to your phone. You can set or change the IP address on your phone from the network connection menu.

Your phone supports IP version 4 (IPv4), IP version 6 (IPv6), and IPv4 and IPv6. IPv4 and IPv6 is the default setting. The IP parameters can be assigned automatically by the network, or you can set them manually.

Follow the steps in the following sections as needed to change your IPv4 or IPv6 address.

Follow these steps to change or set your IPv4 network.

If your network supports both IPv4 and IPv6, you may also need to set the IPv6 settings. For how to change IPv6 settings, see .

1

Press Settings the Settings hard key.

2

If prompted, enter the password to access the Settings menu. You can get the password from your administrator.

3

Navigate to the Network and service section and go to Network connection > Network settings.

4

In the IPv4 section, configure the following settings as needed.

Parameters

Options

Default

Description

DHCP

On

Off

On

Enable or disable DHCP on your phone.

Enable DHCP to allow your phone to get an IP address from the DHCP server. Otherwise, disable DHCP and manually assign an IP address to your phone.

IPv4 address

Available only when DHCP is disabled.

You must assign an IP address to the phone when DHCP is disabled.

Subnet mask

Available only when DHCP is disabled.

You must identify the subset mask used by the phone when DHCP is disabled.

Gateway

Available only when DHCP is disabled.

Identify the default router for the phone to use when DHCP is disabled.

IPv4 DNS address 1

IPv4 DNS address 2

IPv4 DNS address 3

Specify the Primary Domain Name System (DNS) server (IPv4 DNS address 1) and optional backup DNS servers (IPv4 DNS address 2 and 3) that the phone uses.


 
The IPv4 DNS address 3 option is available only on phones that are registered to Cisco Unified Communications Manager.
TFTP server 1

 
This option is applicable to phones registered to Cisco Unified Communications Manager and available only when Alternate TFTP is enabled.

Primary Trivial File Transfer Protocol (TFTP) server that the phone uses. If you are not using DHCP in your network and you want to change this server, you must use the TFTP Server 1 option.

If Alternate TFTP is enabled, enter a non-zero value for the TFTP Server 1 option.

If neither the primary TFTP server nor the backup TFTP server is listed in the CTL or ITL file on the phone, you must unlock the file before you can save changes to the TFTP Server 1 option. In this case, the phone deletes the file when you save changes to the TFTP Server 1 option. A new CTL or ITL file downloads from the new TFTP Server 1 address.

When the phone looks for the TFTP server, the phone gives precedence to manually assigned TFTP servers, regardless of the protocol. If your configuration includes both IPv6 and IPv4 TFTP servers, the phone prioritizes the order that it looks for the TFTP server by giving priority to manually assigned IPv6 TFTP servers and IPv4 TFTP servers. The phone looks for the TFTP server in this order:

  1. Any manually assigned IPv4 TFTP servers

  2. Any manually assigned IPv6 servers

  3. DHCP assigned TFTP servers

  4. DHCPv6 assigned TFTP servers

TFTP server 2

 
This option is applicable to phones registered to Cisco Unified Communications Manager and available only when Alternate TFTP is enabled.

Optional backup TFTP server that the phone uses if the primary TFTP server is unavailable.

If neither the primary TFTP server nor the backup TFTP server is listed in the CTL or ITL file on the phone, you must unlock either of the files before you can save changes to the TFTP Server 2 option. In this case, the phone deletes either of the files when you save changes to the TFTP Server 2 option. A new CTL or ITL file downloads from the new TFTP Server 2 address.

If you forget to unlock the CTL or ITL file, you can change the TFTP Server 2 address in either file, then erase them by pressing Erase from the Security Configuration menu. A new CTL or ITL file downloads from the new TFTP Server 2 address.

When the phone looks for the TFTP server, it gives precedence to manually assigned TFTP servers, regardless of the protocol. If your configuration includes both IPv6 and IPv4 TFTP servers, the phone prioritizes the order that it looks for the TFTP server by giving priority to manually assigned IPv6 TFTP servers and IPv4 TFTP servers. The phone looks for the TFTP server in the following order:

  1. Any manually assigned IPv4 TFTP servers

  2. Any manually assigned IPv6 servers

  3. DHCP assigned TFTP servers

  4. DHCPv6 assigned TFTP servers
