5.5.5 Automatic Setup
[NTP Time Information]
•
The time set through NTP will apply the same to all PTs connected to the PBX, regardless if an IP extension
is located in another time zone.
•
The PBX provides NTP server information to KX-UT extensions (® 5.2.2.1 KX-UT Series SIP Phones) if
the NTP server setting is enabled. If an NTP server has been specified through system programming,
KX-UT extensions will retrieve their time from that server. The PBX uses its own IP address as the NTP
server for the KX-UT extension.
If NTP server is disabled, the time for KX-UT extensions must be set individually at each telephone.
