The Specific format in configuring IPv6 on Yealink 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 (for example, "[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.
