Check network configuration via phone user interface at the path
Settings
->
Advanced
(default password: admin) ->
Network
->
WAN Port
->
IPv4
(or
IPv6
). If the Static IP is
selected, select DHCP instead.
Is there a specific format in configuring IPv6 on Yealink IP phones?
Scenario 1:
If the IP phone obtains the IPv6 address, the format of the URL to access the web user interface
is “
[IPv6 address]” or
“
http(s)://[IPv6 address]
”. For example, if the IPv6 address of your phone is
“fe80::204:13ff:fe30:10e”, you can enter the URL (e.g., “[fe80::204:13ff:fe30:10e]” or
“http(s)://[fe80::204:13ff:fe30:10e])” in the address bar of a web browser on your PC to access
the web user interface.
Scenario 2:
Yealink IP phones support using FTP, TFTP, HTTP and HTTPS protocols to download
configuration files or resource files. You can use one of these protocols for provisioning.
When provisioning your IP phone obtaining an IPv6 address, the provisioning server should
support IPv6 and the format of the access URL of the provisioning server can be “
tftp://[IPv6
address or domain name]
”. For example, if the provisioning server address is “2001:250:1801::1”,
the access URL of the provisioning server can be “tftp://[2001:250:1801::1]/”. For more
information on provisioning, refer to

Time and Date Issues
Why doesn’t the IP phone display time and date correctly?
Check if the IP phone is configured to obtain the time and date from the NTP server
automatically. If your phone is unable to access the NTP server, configure the time and date
manually.
Display Issues
Why is the touch screen blank?
Do one of the following:
Ensure that the IP phone is properly plugged into a functional AC outlet.
Ensure that the IP phone is plugged into a socket controlled by a switch that is on.
