Dear Team,
I have CUCM 11.5 version and my office requested me to add Corona Advisory which you might have seen it already from your belonging GSM service provider are currently doing it. When I call someone, until Party B pick up the call, i want to listen the Corona Advisory instead of Ringback tone. If Cisco CUCM allows this option, could you please advise me how to apply this future. As you know Corona is not giving time and your urgent advise is much appreciated. Thank you so much
