## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great to have phones in places that PoE won't reach
  

*by V***O on Reviewed in the United Kingdom on 24 August 2020*

Ideally should be built into the Yealink phones as standard, however, great addition to get your Yealink phone connected.You do need to ensure that you're on the latest firmware - older firmware does not have the support for the USB device and simply won't work.Once you're on however works like a dream.

### ⭐⭐⭐⭐⭐
