Business phones?
Scenario 1:
If the Skype for Business phone obtains the IPv6 address, the format of the URL to access the
web user interface is "
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 Skype for Business 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 Skype for Business 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]
"
"2001:250:1801::1", the access URL of the provisioning server can be "tftp://[2001:250:1801::1]/".

Audio Issues

How to increase or decrease the volume?
Press the volume key to increase or decrease the ringer volume when the Skype for Business
phone is idle or ringing, or to adjust the volume of engaged audio device (handset,
speakerphone or headset) when there is an active call in progress.
Why do I get poor sound quality during a call?
If you have poor sound quality/acoustics like intermittent voice, low volume, echo or other
noises, the possible reasons could be:
Users are seated too far out of recommended microphone range and sound faint, or are

seated too close to sensitive microphones and cause echo.
Intermittent voice is mainly caused by packet loss, due to network congestion, and jitter,

due to message recombination of transmission or receiving equipment (e.g., timeout
handling, retransmission mechanism, buffer under run).
Noisy equipment, such as a PC or a fan, may cause voice interference. Turn off any noisy

equipment.
Line issues can also cause this problem; disconnect the old line and redial the call to ensure

another line may provide better connection.
