Hello, our customers need possibility to play audio advertisements to their clients while they are on hold or in queue. The option we use now is custom single pre-recorded file with music and announcements, and I believe you're agree, this is not the best way to do it. Having possibility to upload new files (as well as manage them) and play every XX seconds randomly or according to order among to music on hold. This will save huge amount of time for admin and Call Center Managers. Thanks!
