Administrator’s Guide for W60P/W53P/W41P DECT Phones

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
Display time and date incorrectly
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.
Phone Book Issues
Difference between a remote phone book and a local phone book
A remote phone book is placed on a server, while a local phone book is placed on the IP phone flash. A remote phone
book can be used by everyone that can access the server, while a local phone book can only be used on a specific
phone. A remote phone book is always used as a central phone book for a company; each employee can load it to
obtain the real-time data from the same server.
Audio Issues
Increasing or decreasing the volume
Press the volume key to increase or decrease the ringer volume when the IP phone is idle or ringing, or to adjust the
volume of the engaged audio device (speakerphone or headset) when there is an active call in progress.
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:
l
Users are seated too far out of recommended microphone range and sound faint, or are seated too close to sensitive
microphones and cause echo.
l
Intermittent voice is mainly caused by packet loss, due to network congestion, and jitter, due to message recom-
bination of transmission or receiving equipment (for example, timeout handling, retransmission mechanism, buffer
under run).
l
Noisy equipment, such as a computer or a fan, may cause voice interference. Turn off any noisy equipment.
l
Line issues can also cause this problem; disconnect the old line and redial the call to ensure another line may
provide a better connection.
There is no sound when the other party picks up the call
If the caller and receiver cannot hear anything - there is no sound at all when the other party picks up the call, the pos-
sible reason could be: the phone cannot send the real-time transport protocol (RTP) streams, in which audio data is
transmitted, to the connected call.
Try to disable the 180 ring workaround feature.
