8.1.9 Network Time Protocol (NTP)

8.1.9 Network Time Protocol (NTP)
The PBX 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 PBX or by contacting
an NTP server directly.
For a SIP phone to receive and update its time setting via the PBX, 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 PBX as their NTP server.
(The PBX 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.
