Question: In a scenario with one active, one held, and one waiting call on a User Equipment (UE), what happens to the waiting call after successfully transferring the active and held calls using the Explicit Call Transfer feature?
Option 1: The waiting call is automatically connected to the UE without notification.
Option 2: The waiting call is dropped due to the transfer of the other two calls.
Option 3: The served subscriber is offered a normal notification that there is a new waiting call, as for a normal terminating call.
Option 4: The UE places the waiting call on hold indefinitely until further action.
Explanation: This correct answer reflects the proper handling of calls in a telecom network after an Explicit Call Transfer. By notifying the subscriber of a new waiting call, the network ensures seamless communication management, aligning with standard MMI behaviors for User Equipment (UE), particularly in scenarios involving multiple concurrent calls and call transfers.
