Please upgrade to V73-Beta version to test if it can solve the issue.
You can get the rom file and other manuals from here : ftp://Coco%20Ke:9YKQ69mv@ftp.yealink.com...V73-Beta)/

P.S: Please upgrade the base and handset both to the V73.

Hello Support,

As down time was a problem and response quite slow I decided to replace the phone with a Siemens C610IP.
You also need to work on Windows 8 software support for the handset upgrade.

Thanks for the late reply.
