The DECT cordless phone beeps 4-5 times when a call is answered.

How do I resolve this.


This is a known issue with the W60x, & W70x bases and W56, W59 handsets.


Upgrade both the base and handsets to the latest version of firmware(s) from https://support.yealink.com 

Then apply the "phone_setting.outgoing_call_answer_tone.enable = 0" config file (attached)

If the above config update doesn't work can you try this.
  1. Change the above config command to = 1 and update
  2. Then change back to = 0 and update.
