We have added a new addition to the voice broadcasting call back.
You can now put in "-1" by the Sound ID to allow the last call that was sent to that specific caller ID to be replayed.
So if you were sending out multiple calls to different grades, when the parent calls back they will hear the last message that was sent to that phone.
Note: With this option set, if a phone number was not on your list they will not be able to hear the last recording.
Summary:
Blank: Will play to any caller that calls the number, the last recording send out.
-1: Will play the last recording sent to that caller ID.
Sound ID: Will play to any caller that specific recording.
