A
DNS Query Mode Do parallel or sequential DNS Query. With parallel
DNS query mode, the SPA9000 sends the same
request to all the DNS servers at the same time
when doing a DNS lookup, the first incoming reply
is accepted by the SPA9000.
Defaults to parallel.
DNS Query TTL Ignore
(Not applicable to
Cisco SPA525G or
Cisco SPA525G2.)
If enabled, the phone continues to use the
previous cached DNS result if the DNS server
does not respond when the phone tries to renew
its DNS query.
When disabled, the phone uses the previous TTL
value and clears the DNS query result cache.
Syslog Server Specify the syslog server name and port. This
feature specifies the server for logging IP phone
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 The debug server name and port. This feature
specifies the server for logging IP phone debug
information. The level of detailed output depends
on the debug level parameter setting.
Debug Level The debug level from 0-3. 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.
Layer 2 Logging Used for IP phone network layer debugging
purposes. Do not use except when advised to do
so by Cisco technical support, as this may impact
system performance. Set to no by default.
