If you are on a call, and another call comes in:
Tell the current caller to hold, and simply press ANSWER. This will automatically put the first call on hold, and will answer the second call.
If you have several calls on hold:
Each call will appear on the screen. So, the easiest way to address each call is to use the arrow keys to highlight the call you need. Then select the action you want to perform.
If you have any questions or concerns, please contact the FSA Support Center.
