We have programmed the auto attendant for 3 calling groups. Each has it's own delayed announcement, however while waiting for the group member to pick up the call, it continues to ring while on que rather than play music or be silent waiting for secondary announcemnt. Ex: call comes in to auto att; caller selects selector code 1 - goes to group 771, announcement telling caller to hold someone will be right with them, then the caller hears ringing in the background. We want to remove this ringing. Please help.
