Headset auto answer waiting call T43U and WH62

[TravisD]

This is the reply from Arthur - Yealink Headset Engineer.

"Our headset's working principle, is when in a call, and the second call comes in, one click the call control button will hang up the current call and answer the new call.

If you want to hang up the current call only, please do it from the IP Phone."

Its weird then it never happens on my T41s that I use as my desk phone.
Also who would ever want this feature.. my customers surly don't and its caused nothing but dramas since day one.
