All calls will be terminated when the master headset loses link or is placed on the cradle.

Line swapping
In the case two calls are established in two different lines, one of them is being the active call in the active line. To
make the line swapping simpler, active line is swapped automatically depending on call activities change. It can be one
of the following scenarios:
User makes an outgoing call by softphone or desktop phone.
User retrieves USB held call by softphone.
User swaps USB call by softphone.
User accepts an incoming call.
Call from first active line is ended and other call is existed in second inactive line.
The user can also swap the line from the base manually. When a line is swapped successfully, between two different
lines, a visible indication is shown on base.
