Operating Parameters
DNS2IP
Description
This parameter is for setting the secondary domain name server (DNS) IP, if the DHCP server does not
provide one. If DHCP provides DNS2IP (if it is non-zero), this parameter overwrites the DHCP-supplied
value. You cannot specify a port parameter. The Cisco ATA uses the default DNS port only.

Domain
Description
The Cisco ATA uses the value of this parameter for a DNS search if either the TftpUrl or CM0orCA0
parameters do not contain a fully qualified domain name. For example, if cm1 is specified as the
Cisco CallManager URL, and cisco.com is the value of the Domain parameter, then the Cisco ATA uses
cm1@cisco.com for its DNS search.
The following values are valid:
• Dot (.) or blank—Uses DHCP-provided IP address if available; otherwise use static IP address.
• 0—Uses DHCP-provided domain name if available; otherwise use static IP address.
• *—Uses Cisco ATA MAC address.
• String—Uses specified string.
