Hello to all..if I use one of our phones and I want to make an announcement that will be hear through every phone in the building I simply hit "#39" and then I start talking....this works great with no problems... however is there a way so that when I want to make an announcement, first a loud "beep" sound will be send to every phone in the building as an "attention getter"?...after the beep I would start talking making the announcement. Please let me know how I can make this possible, it would be of HUGE help. Thanks a lot :-)
