When DHCP is disabled, you must set the subnet mask.
• Gateway address—Identifies the default router used by the
phone.

server that the phone uses. When DHCP is disabled, you

server that the phone uses. When DHCP is disabled, you
must set this field manually.
When you assign an IP address using this field, you must also
assign a subnet mask and a gateway address. See the Subnet Mask
and Default Router fields in this table.
