Yealink IP phones support using the NTP server address offered by DHCP.
DHCP option 42 is used to specify a list of NTP servers available to the client by IP
address. NTP servers should be listed in order of preference. DHCP option 2 is used to
specify the offset of the client's subnet in seconds from Coordinated Universal Time
(UTC).
To update time with the offset time offered by the DHCP server, make sure the DHCP
Time feature is enabled at the web path Settings->Time & Date->DHCP Time. For more
information on how to configure DHCP time feature, refer to NTP Time Server on page
147.
