Unable to Obtain IP Address
Last Updated: 04/10/2014

If the phone is unable to obtain an IP address, then it is not connecting to your network. You can try to manually configure the network settings to get around this. First, you will need to know what an available IP address is on your network, as well as the subnet and gateway (see your network administrator if you are not sure where to find this).

The phone is capable of obtaining all of its IP configuration data from a DHCP server. When a DHCP server is not available, static address parameters can be used. Selecting Static requires the manual entry of other several network parameters including:
• IP address of the phone
• Default gateway IP address
• Subnet mask
• DNS address

To set the Network Mode:
• Press the options button(looks like sheet of paper with edge folded), then select 1. Network Configuration, then 1. Network Mode.
• Scroll through the Network Mode options using the Down softkey and press Select to select a Mode (select Static).

IP Address:
By default the phone is configured to use DHCP to automatically assign an IP address and other LAN
parameters. Assigning a static address for the Network Mode requires manual entry of an IP address and
other parameters stated in the previous section. The phone requires a valid available IP address for proper operation.
To set the IP Address:
• Press the options button, then select 1. Network Configuration, then 2. IP Address.
• Input the IP Address using the dial pad and press the OK softkey to save the changes.

Subnet Mask:
Selecting static addressing for the Network Mode requires manual entry of a subnet mask. The IP phone
requires a valid subnet for proper operation.

To enter the Subnet Mask:
• Press the options button, then select 1. Network Configuration, then 3. Subnet.
• Input the Subnet Mask using the dial pad and press the OK softkey to save the changes.

Default Gateway:
Selecting static addressing for the Network Mode requires manual entry of a default gateway address. The
IP Phone requires a valid default gateway address for proper operation.
To assign the Default Gateway address:
• Press the options button, then select 1. Network Configuration, then 4. Default Gateway.
• Input the Default Gateway IP address using the dial pad and press the OK softkey to save the changes.
Once these have been configured, you can back out of the menu, and reboot the phone.
