Announcement Center and GSC3510


I am setting up some GSC3510 speakers and am using the announcement center. It looks like I need to whitelist the announcement center code. Is there a way to whitelist numbers like I can for outbound routes or call plan patterns


It looks like I can use Pcodes to add stuff to the white list so I guess this is better than adding them to all the speakers separately

But I cannot put in multiple numbers. I tried to put multiple numbers in and it doesn’t seem to be working.
