8.1.9 Network Time Protocol (NTP)
The KX-NS300 can be configured to contact an NTP server to receive and update its time setting automatically.
KX-UT series SIP phones can receive and update their time setting either through the KX-NS300 or by
contacting an NTP server directly.
For a SIP phone to receive and update its time setting via the KX-NS300, the NTP server feature must be
enabled. To enable this feature refer to "27.2.4 Network Service—[2-5] Server Feature—NTP" in the PC
Programming Manual.
If the NTP server feature is enabled:
•
Case 1: An NTP server is specified in Web Maintenance Console.
–
The SIP phones use the specified IP address and contact the NTP server directly.
•
Case 2: An NTP server is not specified in Web Maintenance Console.
–
The SIP phones use the IP address of the KX-NS300 as their NTP server.
(The KX-NS300 acts as an NTP server for the SIP phones.)
To specify the IP address of the NTP server, refer to "10.1.2 PBX Configuration—[2-1-2] System—Date &
Time—SNTP / Daylight Saving" in the PC Programming Manual.
If the NTP server feature is disabled, the SIP phones use their own time settings.
