W52 High pitched noise - nicvon - 10-28-2014 03:06 PM Hi I have about 8 x W52 running off 4 different Bases around our office. 3 of the handsets periodically (when answering) have a high pitched noise and the user cannot hear anything and neither can the caller. I have taken a video of the problem: http://youtu.be/zgno0TufW80 All 3 phones are on different base stations and the problems happen at different times at different places around the office. The phones are between 2 - 6 months old. I have other phones running the same firmware off the same base stations which have not had any problems. Please can you make some suggestions Phones FIRMWARE: 25.30.0.50 MAC: 00-15-65-53-33-5A RE: W52 High pitched noise - Coco_Yealink - 10-29-2014 03:18 PM Hello nicvon, Could you please help to upgrade both Base and Handset to V73, and then test again? firmware Thx RE: W52 High pitched noise - nicvon - 10-29-2014 03:31 PM Thanks Coco I will try it and report back in a few days. |
