Solved Upgraded to V15.5 from V14 Yealink Phones now got Phone Book/Call History Issue

[SimonCC]

Hi

We finally upgraded to V15.5 from V14 and ended up with various issues on Yealink phones, seems to be on most phones. I did upgrade firmware on various units, since some stated Not Supported, but all now look clean.

Issues as follows: (We did not have any problems on V14)

Network Call Log (History): Error:States XSI Information is Complete
3CX Phone Book Error: Failed to Download Remote Phone Book

Please can anyone help?

Regards,

Simon.
