• DNS Server Order—Method for selecting the DNS server. The options are:
- Manual—Enter the IP address of the DNS server manually; do not use
the DHCP-supplied DNS table.
- Manual/DHCP—Look for a manual entry of the IP address of the DNS
server. Use the DHCP-supplied DNS table if it is not found.
- DHCP/Manual—Use the DHCP-supplied DNS table. If not found, look for
a manual entry of the IP address of the DNS server.
DNS Query Mode—Parallel or Sequential DNS query. A parallel DNS query sends
the same DNS lookup request to all of the DNS servers at the same time. The first
incoming reply is accepted by the phone. A sequential query polls the DNS
servers in sequence. Defaults to parallel. Not available on Cisco WIP310,
Cisco SPA525G or Cisco SPA525G2.
Syslog Server—Syslog server name and port for logging system information and
critical events. If both Debug Server and Syslog Server are specified, Syslog
messages are also logged to the Debug Server.
Debug Server—Debug server name and port for logging debug information. The
level of detailed output depends on the Debug Level.
Debug Level—The debug level ranges from 0 to 3. The higher the level, the more
debug information is generated. Zero (0) means no debug information is
generated. To log SIP messages, you must set the Debug Level to at least 2.
Defaults to 0.
NTP Enable—Enables the Network Time Protocol (NTP). Applies to the
Cisco SPA525G or Cisco SPA525G2 only.
Primary NTP Server—IP address or name of the primary NTP server used to
synchronize its time. Defaults to blank.
Secondary NTP Server—IP address or name of the secondary NTP server used
to synchronize its time. Defaults to blank.
Enable Bonjour—Bonjour is used by Office Manager and Cisco Configuration
Assistant to discover the Cisco IP phones. Choose yes to enable or no to disable.
Applies to the Cisco SPA525G or Cisco SPA525G2 only.
