Swtich between calls in one single tap

[julien]

Hello,
my users are complaining about the "amount of time" they need to switch between phone calls (on Hold).

Either they have to use the arrows and click ok to pickup the line

Or

They have to tap one time on the blinking bullet and then tap another one time to pickup the line again.

Is there any way to change this behavior and pickup the line at the first tap ?

Thank you.
