Question: With both Call Hold and Call Waiting active on a User Equipment (UE), having one active and one held call, how can a user clear the active call to accept the third incoming (waiting) call without affecting the held call?
Option 1: Enter 1 followed by SEND
Option 2: Enter 2 followed by SEND (this action will not affect the call state)
Option 3: Automatically, after a time-out period, the active call is cleared for the waiting call
Option 4: Only by releasing the held call first
Explanation: According to the specified behavior for managing multiple calls on a UE with Call Hold and Call Waiting features enabled, entering 1 followed by SEND is the correct action to clear the active call and accept the waiting (third) call without affecting the status of the held call. This ensures seamless management of concurrent calls, prioritizing the acceptance of the new incoming call while maintaining the hold state of another.
