Active call issues with Yealink hardphones

[Coco_Yealink]

Hi bsanders,

The problem what you mentioned is during a call,when you press the Dsskey(eg.speed dial), then the presence call disconnected,right?
But I am a doubt that why you want to press speed dials DSSkey during a call? Could you please tell me your real scene.
And there is no method to "hide or disable" the DSSkey while on call .If you don't want to use it, why not just no press the DSSkey during a call?

Thx
